Everest Three Passes Trek Monthly Weather Guide

Overview

Have you ever dreamed of standing atop the world, surrounded by snow-capped peaks and pristine glaciers? The Everest Three Passes Trek in Nepal's Everest region is one of the most thrilling and challenging adventures you can embark upon. This epic journey takes you across three high-altitude passes, Kongma La (5,535m), Cho La (5,420m), and Renjo La (5,360m), offering jaw-dropping views of Mount Everest, Lhotse, Makalu, and Cho Oyu.

But here's the thing: timing is everything when it comes to trekking in the Himalayas. The weather can make or break your experience, turning a dream adventure into a survival challenge or a picture-perfect journey you'll cherish forever. That's why understanding the monthly weather patterns is crucial for planning your Everest Three Passes Trek.

This comprehensive guide will walk you through every month of the year, helping you understand what to expect weather-wise so that you can choose the perfect time for your adventure. Whether you're a seasoned trekker or planning your first Himalayan expedition, this guide has got you covered.

Is the Everest Three Passes Trek Safe?

Let's address the elephant in the room: yes, the Everest Three Passes Trek is generally safe, but it demands respect, preparation, and proper planning. This isn't your average weekend hike—it's a high-altitude adventure that pushes your physical and mental limits. The trek's safety largely depends on several factors. Weather conditions play a massive role, which is exactly why we're diving deep into monthly patterns in this guide. During favorable seasons like spring and autumn, the trails are well maintained, and thousands of trekkers complete the journey each year.

However, the high altitude poses legitimate risks. Acute Mountain Sickness (AMS) is a real concern when you're crossing passes above 5,300 meters. That's why acclimatization days are non-negotiable. You need to give your body time to adjust to decreasing oxygen levels. Rushing through this trek is like playing Russian roulette with your health. Weather unpredictability is another factor. Even during the best seasons, mountain weather can change dramatically within hours. Clear skies can transform into blizzards, and sunny mornings can give way to afternoon snowstorms. This is why hiring an experienced guide who knows the terrain and weather patterns is highly recommended.

Physical fitness matters too. You'll be trekking for 15-20 days, covering rugged terrain, crossing glaciers, and climbing steep ascents. If you're not in good shape, you're not just risking discomfort; you're potentially endangering yourself and your group. That said, with proper preparation, acclimatization, quality gear, and good timing, the Everest Three Passes Trek is absolutely achievable and safe for determined trekkers. Thousands complete it successfully every year, returning home with memories that last a lifetime.

Everest Three Passes Trek Weather Month by Month

Spring (March–May): The Blooming Season for the Everest Three Passes Trek

Spring is when the Himalayas shake off winter's icy grip and burst into life. The rhododendrons bloom, painting the hillsides in brilliant reds and pinks, and the weather becomes increasingly stable. This is one of the two peak seasons for the Three Passes Trek, and for good reason.

Everest Three Passes Trek in March

March marks the transition from winter to spring, and it's a fascinating time to trek. The weather is still quite cold, especially at higher elevations, but the trails start becoming more accessible as snow begins to melt.

Daytime temperatures at lower elevations (around Lukla and Namche Bazaar) range from 10-15°C, which is quite pleasant for trekking. However, once you climb higher, temperatures can drop significantly. At the passes themselves, you're looking at daytime highs of around -5°C to 0°C, with nighttime temperatures plummeting to -15°C or lower.

Visibility is excellent during March, making it perfect for photography enthusiasts. The crisp, cold air creates incredibly clear conditions, and you'll get stunning sunrise and sunset views over the Himalayan giants.

Everest Three Passes Trek in April

April is when the Three Passes Trek truly comes alive. This is arguably the best month for this trek, combining stable weather with comfortable temperatures and spectacular scenery.

The weather in April is remarkably stable. The skies remain mostly clear, with minimal precipitation. Daytime temperatures at lower elevations reach a comfortable 15-20°C, while higher altitudes and passes see temperatures ranging from 0°C to -10°C. Nights are still cold, especially at high camps, but nowhere near as brutal as winter months.

One thing to keep in mind: April is peak season, which means more trekkers on the trails. Popular teahouses fill up quickly, so booking accommodation in advance or arriving early each day is wise. The upside? The social atmosphere is fantastic, and you'll meet fellow adventurers from around the world.

Everest Three Passes Trek in May

May continues the favorable spring conditions, though it marks the end of the peak season as the monsoon approaches. Early May is still excellent for trekking, but as the month progresses, afternoon clouds become more frequent.

Temperatures in May are the warmest you'll experience on this trek. Lower elevations can reach 20°C or higher during the day, making those initial days quite warm. At higher altitudes and passes, daytime temperatures range from 0°C to 5°C, with nights dropping to around -10°C.

One advantage of trekking in late May is that it's the shoulder season, meaning fewer crowds but still good weather. The downside is the increasing possibility of pre-monsoon showers, especially in the latter half of the month. These are usually short afternoon showers rather than all-day rain, but they can make trails muddy and increase avalanche risk on the passes.

Monsoon (June–August): The Wet and Challenging Season

The monsoon season in Nepal typically runs from June through August, bringing heavy rainfall to most of the country. However, the Everest region, including the Three Passes Trek, sits in a rain shadow, receiving less precipitation than areas like Annapurna. That said, this is still the most challenging season for trekking.

Everest Three Passes Trek in June

June marks the beginning of monsoon season, and you'll definitely notice the change. The weather becomes increasingly unpredictable, with cloudy skies, frequent rain, and occasional snow at higher elevations.

Temperatures in June are relatively warm at lower elevations, ranging from 15-20°C during the day. However, the increased humidity makes it feel warmer and less comfortable. At higher altitudes, temperatures remain around 0°C to 5°C during the day, with nights still dropping well below freezing.

Trail conditions deteriorate in June. Paths become muddy and slippery, increasing the risk of accidents. Leeches appear at lower elevations, which can be unpleasant. Additionally, afternoon rain increases the risk of landslides on certain sections of the trail.

Everest Three Passes Trek in July

July is the heart of the monsoon season and generally considered the least favorable month for the Three Passes Trek. The weather is at its wettest, most unpredictable, and potentially dangerous.

Rainfall is frequent in July, though the Everest region still receives less than in other parts of Nepal. You can expect rain almost daily, usually in the afternoons and evenings, but sometimes lasting throughout the day. At higher altitudes, this precipitation falls as snow, which can accumulate quickly and create hazardous conditions on the passes.

Temperatures remain relatively warm at lower elevations (15-20°C), but the high humidity makes trekking uncomfortable. At high altitudes, temperatures hover around 0°C to 5°C during the day, dropping below -5°C at night.

Trail conditions are at their worst. Muddy, slippery paths are the norm. River crossings become more dangerous as water levels rise. The risk of avalanches on the passes increases significantly with fresh snow accumulation. Many experienced guides and trekking agencies advise against attempting this trek in July due to these safety concerns.

Everest Three Passes Trek in August

August continues the monsoon pattern but typically sees slightly improving conditions toward the end of the month. It's still not an ideal time for the Three Passes Trek, but it's marginally better than July.

Weather patterns in August are similar to July—expect frequent afternoon rain, cloudy skies, and limited mountain views. However, late August sometimes experiences brief clear windows as the monsoon begins to weaken, offering occasional spectacular views.

Temperatures remain comfortable at lower elevations (15-20°C) with high humidity. Higher altitudes see daytime temperatures around 0°C to 5°C, with nights dropping to -5°C or below.

Late August can be considered if you're an experienced trekker with flexible timing and don't mind the high probability of poor weather. The landscapes are lush and green from the monsoon rains, creating a different kind of beauty compared to the dry seasons.

Autumn (September–November): The Prime Trekking Season

Autumn is the crown jewel of trekking seasons in Nepal, and the Three Passes Trek is no exception. After the monsoon clears, the mountains reveal themselves in all their glory, the weather stabilizes, and trekking conditions become ideal.

Everest Three Passes Trek in September

September marks the transition from monsoon to autumn, and it's a beautiful time to trek. The monsoon rains have washed away the dust, leaving the air crystal clear and the landscapes vibrant green. Early September can still see occasional rain as the tail end of the monsoon passes through, but by mid-month, conditions improve dramatically. The skies are clear, revealing stunning mountain vistas that rival any time of year. Temperatures in September are comfortable across all elevations. Lower altitudes enjoy pleasant 15-20°C daytime temperatures, while higher regions and passes see 0°C to 5°C during the day, with nights around -5°C to -10°C.

Visibility is outstanding in September. The post-monsoon atmosphere is incredibly clear, offering some of the best mountain photography opportunities of the year. Sunrise and sunset views are particularly spectacular, with the clean air creating vivid colors.

Everest Three Passes Trek in October

October is widely considered the absolute best month for the Three Passes Trek. The weather is at its most stable, conditions are perfect, and every element aligns to create ideal trekking circumstances. The weather in October is remarkably consistent. Clear blue skies dominate, with minimal precipitation. Day after day of perfect trekking weather is the norm rather than the exception. This reliability makes planning easier and reduces the risk of weather-related complications.

Temperatures in October are ideal for high-altitude trekking. Lower elevations see comfortable 10-15°C daytime temperatures, while higher altitudes and passes range from -5°C to 5°C during the day. Nights are cold, especially at high camps (-10°C to -15°C), but not as extreme as winter months. The downside of October's perfection is popularity. This is peak season, and the trails can feel crowded, especially on popular sections. Teahouses fill up quickly, particularly in places like Namche Bazaar, Dingboche, and Gorak Shep. Booking ahead or arriving early each day is essential. Some trekkers find the social atmosphere energizing, while others prefer more solitude.

Everest Three Passes Trek in November

November extends the excellent autumn conditions, though weather patterns begin shifting toward winter as the month progresses. It remains one of the best times for the Three Passes Trek, offering a balance between good conditions and fewer crowds. Early November maintains October's favorable conditions, stable weather, clear skies, and comfortable temperatures. However, as the month progresses, temperatures begin dropping noticeably, especially at night.

Daytime temperatures at lower elevations range from 10-15°C in early November, dropping to 5-10°C by month's end. At higher altitudes and passes, daytime temperatures range from -5°C to 0°C, with nights plummeting to -15°C or lower, especially in late November. Late November is ideal for experienced trekkers who want good weather without peak season crowds and don't mind colder temperatures. It's also slightly cheaper, as some teahouses and guides offer shoulder-season discounts.

Winter (December–February): The Cold and Serene Season

Winter in the Everest region is harsh, beautiful, and challenging. Temperatures plummet, snow accumulates, and the mountains take on a pristine, otherworldly quality. This season is for hardcore trekkers seeking solitude and willing to face extreme conditions.

Everest Three Passes Trek in December

December marks the beginning of winter, and conditions become increasingly challenging. The weather is generally stable, clearer than monsoon months, but the cold is intense and unforgiving. Temperatures in December are significantly lower than in other months. At lower elevations, daytime temperatures range from 5-10°C, which is still manageable. However, at higher altitudes and the passes themselves, daytime temperatures hover around -10°C to -5°C, with nights dropping to -20°C or even lower.

Teahouse availability becomes an issue in December. Many lodges close for winter, especially at higher elevations. Those that remain open offer basic heating (usually a central stove in the dining area), but rooms are freezing. Some trekking agencies recommend carrying camping equipment as a backup. Snow accumulation on the passes increases throughout December, making crossings more technical and potentially requiring specialized equipment like crampons, ice axes, and ropes. Hiring an experienced guide is absolutely essential for winter treks.

Everest Three Passes Trek in January

January is the coldest month in the Everest region and represents peak winter conditions. This is the most extreme time to attempt the Three Passes Trek, suitable only for experienced mountaineers with proper equipment and preparation. Temperatures in January are brutal. At lower elevations, daytime highs reach only 5°C, with nights dropping below -10°C. At higher altitudes and the passes, daytime temperatures range from -15°C to -10°C, with nighttime temperatures plummeting to -25°C or even lower. These are not hypothetical numbers, this is a genuine life-threatening cold if you're unprepared.

The extreme cold affects everything. Water bottles freeze solid unless kept inside your sleeping bag. Electronics fail. Battery life drops dramatically. Simple tasks like adjusting the gear or eating become challenging with numb fingers. Why would anyone trek in January? The solitude is absolute, the mountain scenery is pristine and untouched, and the challenge itself attracts hardcore adventurers. However, this should only be attempted by very experienced trekkers with proper winter mountaineering skills, high-quality gear, and ideally, a support team.

Everest Three Passes Trek in February

February represents late winter, and conditions begin slowly improving as the month progresses. It's still extremely cold and challenging, but slightly more accessible than January. Temperatures in February remain very cold but show marginal improvement. Lower elevations see daytime temperatures around 5-10°C, while higher altitudes and passes experience -10°C to -5°C during the day. Nights remain frigid at -20°C or lower at high elevations, though slightly warmer than January.

Weather stability in February is excellent. Clear, sunny days are the norm, offering outstanding visibility. The crisp winter air creates incredibly sharp mountain views. Snowfall decreases compared to earlier winter months, though occasional snow events still occur. February appeals to adventurous trekkers who want winter conditions and solitude but with slightly better accessibility than January. It's still a challenging month requiring proper preparation, but it's more forgiving than peak winter.

Everest Three Passes Trek Temperature Overview

Understanding temperature patterns helps you pack appropriately and set realistic expectations. Here's a comprehensive overview of temperatures throughout the year at different elevations:

Lower Elevations (Lukla to Namche Bazaar, 2,800-3,440m):

• Spring (March-May): 10-20°C daytime, 0-5°C nighttime

These temperatures are averages and can vary significantly based on specific weather conditions. Wind chill at high altitudes can make temperatures feel much colder than actual readings. Always prepare for colder conditions than expected, as the weather in the mountains is unpredictable.

Everest Three Passes Trek Monthly Rainfall Guide

Precipitation patterns significantly impact trekking conditions, trail safety, and visibility. Here's what to expect throughout the year:

Dry Season (October-May): The Everest region experiences minimal rainfall during these months, with October through April being the driest. You can expect:

• October: 10-20mm total precipitation
• November: 5-15mm total precipitation
• December: 5-10mm total precipitation
• January: 5-10mm total precipitation
• February: 10-15mm total precipitation
• March: 15-25mm total precipitation
• April: 20-30mm total precipitation
• May: 30-50mm total precipitation (increasing as monsoon approaches)

During the dry season, any precipitation at high altitudes falls as snow. Rain at lower elevations is rare and usually brief.

Monsoon Season (June-August): This is the wet season, though the Everest region receives less rainfall than other parts of Nepal due to its rain shadow location:

• June: 60-90mm total precipitation
• July: 90-120mm total precipitation (wettest month)
• August: 80-110mm total precipitation

During the monsoon, expect afternoon thunderstorms and rain almost daily at lower elevations. Higher elevations receive this precipitation as snow. Morning starts are often clear, with the weather deteriorating by afternoon.

Transition Months (September and late May): These shoulder periods show transitional patterns:

• Late May: Increasing afternoon showers as monsoon approaches
• September: Decreasing rainfall as monsoon recedes; early September can still see occasional rain

The beauty of the Everest region's rain shadow effect is that even during the monsoon, rainfall is less intense and frequent than in areas like Annapurna or lower Nepal. However, when it does rain or snow, it can be heavy and persistent.

Understanding these patterns helps you plan rest days, pass crossings, and overall timing. Always check detailed forecasts before crossing passes, as even during dry season, unexpected weather can occur.

Everest Three Passes Trek vs Annapurna Circuit Trek: Which is Better for You?

Both the Three Passes Trek and the Annapurna Circuit Trek are legendary Himalayan adventures, but they offer distinctly different experiences. Understanding these differences helps you choose which suits your preferences and abilities.

Altitude and Difficulty: The Three Passes Trek is significantly more challenging. You cross three passes above 5,300m, with the maximum altitude reaching 5,545m at Kongma La. The Annapurna Circuit's highest point is Thorong La Pass at 5,416m, which you cross once. The Three Passes Trek demands better physical fitness and acclimatization.

Duration: The Three Passes Trek typically takes 18-21 days, while the Annapurna Circuit ranges from 15-20 days, depending on transportation choices and side trips. Both require similar time commitments, though the Three Passes Trek is more consistently demanding.

Scenery: This is subjective, but they offer different landscapes. The Three Passes Trek provides close-up views of the world's highest peaks—Everest, Lhotse, Makalu, Cho Oyu—plus spectacular glacier views. The Annapurna Circuit showcases diverse landscapes from subtropical forests to Tibetan plateaus, with stunning views of the Annapurna range. If you want the prestige and thrill of Everest region trekking, choose Three Passes. If you prefer diverse landscapes and cultural variety, Annapurna appeals.

Weather Considerations: The Annapurna region receives heavier monsoon rainfall, making June-August particularly challenging. The Three Passes Trek's location in the rain shadow makes it slightly more viable during monsoon, though still not ideal. Both treks are excellent during spring and autumn.

Cost: The Three Passes Trek is generally more expensive. Flights to Lukla are pricier than transport to Annapurna starting points. Teahouse costs are higher in the Everest region, and permit fees differ. Budget approximately 20-30% more for the Three Passes Trek compared to the Annapurna Circuit.

Crowds: Both treks see significant crowds during peak season (October-November and April). However, the Three Passes Trek, being more challenging and less famous than the Everest Base Camp Trek, typically has fewer trekkers than the Annapurna Circuit's main route.

Cultural Experience: The Annapurna Circuit offers more cultural diversity, passing through Hindu, Buddhist, and Tibetan communities with varied traditions. The Three Passes Trek is predominantly Sherpa culture throughout, providing deep immersion in Sherpa heritage but less diversity.

Technical Difficulty: The Three Passes Trek requires crossing glacier sections and potentially using crampons during certain seasons. Navigation can be challenging in poor weather. The Annapurna Circuit is more straightforward, with clear trails and less technical terrain.

Which should you choose? If you're seeking the ultimate high-altitude challenge with the prestige of the Everest region, choose the Three Passes Trek. If you want cultural diversity, varied landscapes, and a challenging but slightly less extreme trek, the Annapurna Circuit is ideal. Both are extraordinary adventures that showcase the best of Himalayan trekking.
