Everest Base Camp Trek Weather: Guide 2026

The Everest Base Camp offers the best weather in spring (March to May) and autumn (September to November). These seasons have clear skies, dry trails, and comfortable temperatures, making your trek easy and more enjoyable. The Everest Base Camp Trek weather is difficult to predict, so plan according to the Everest Base Camp weather forecast to ensure safer trekking and better visibility of the mountains. 

Spring brings mild days and blooming flowers, while autumn offers crisp, clear views after the monsoon rains. On the other hand, winter and monsoon seasons are colder, wetter, and harder, so they are better for experienced hikers who want less crowded trails and more adventure. Understanding the weather conditions in the Khumbu region helps you plan for temperature changes, snowfall, and rainfall along the trail.

Whether you want clear skies, fewer crowds, or an adventurous challenge, this guide covers what you need to know to make the most of your Everest Base Camp journey.

 

Why EBC Trek Conditions Vary Throughout the Year

The Everest region experiences unique weather patterns influenced by monsoons, jet streams, and high altitude, creating dramatic seasonal changes unlike typical four-season climates. This makes the Everest Base Camp climate highly variable, from subtropical forests to icy alpine zones. 

There are four main seasons: spring (pre-monsoon), summer (monsoon), autumn (post-monsoon), and winter, each with very different trekking conditions from blooming spring trails to snowy winter landscapes. 

Along the trek, you pass through several climate zones: starting at Lukla (2,860m) with mild temperatures and green valleys, moving to colder and thinner air in Namche Bazaar (3,440m), and finally reaching the alpine desert of Everest Base Camp (5,364m) where temperatures can drop to -25°C at night. 

This wide range means you can start in a T-shirt and need heavy layers by afternoon. Everest Base Camp trek weather can change very fast due to the jet stream and mountain terrain creating microclimates, so clear skies can quickly turn into storms. 

The trail crosses climate zones from subtropical at Lukla with lush greenery, through temperate forested areas around Namche, alpine zones with sparse vegetation higher up, to the icy nival zone near Everest Base Camp, where extreme cold and snow are possible anytime. Understanding these variations helps you prepare smartly for the conditions they will face.​

Best Time for Everest Base Camp Trek Weather

Autumn (September to November) – Best Overall

October is ideal for the Everest Base Camp trek, offering stable conditions and crystal-clear skies. This is peak season for excellent reasons. The monsoon rains have cleared the air, leaving spectacularly clean skies. Mountain views are at their absolute best, with visibility often exceeding 100 kilometres.

Everest Base Camp trek weather during autumn typically shows stable conditions. Daytime temperatures at base camp range from -5°C to 12°C, whilst nights drop to -10°C to -15°C. Lower elevations remain comfortably mild.

The downside? Everyone knows autumn is brilliant, so trails get busy, especially in October. Tea houses fill quickly, and you'll share viewpoints with dozens of trekkers.

Book early and expect standard prices with Himalaya Trekking Nepal.

Spring (March to May) – Second Best Season

April, in particular, is the best Everest Base Camp weather, with mild temperatures and blooming rhododendrons along the trail. Spring brings the Himalayas back to life. Rhododendron forests explode with brilliant reds, pinks, and whites lining lower trails. It's genuinely magical with different scenery in autumn.

Everest base camp trek weather in spring shows gradually warming conditions. March can still feel wintry at higher elevations, but by May, daytime temperatures become comfortable. Expect -10°C to 20°C at base camp.

In spring, especially in May, one challenge you’ll face is that clouds often gather in the afternoon. The mornings usually have the clearest, most beautiful mountain views, so starting your trek early is very important. By walking early, you can enjoy the best sights before the clouds build up later in the day and make the mountains harder to see. This means you get the most out of your trek with clear skies and stunning views during the cooler part of the day.

Winter (December to February) – Cold but Clear

Winter isn't for everyone, but it rewards brave souls with incredible solitude and pristine conditions. The weather in Mount Everest during winter means seriously cold temperatures, with nighttime lows reaching -25°C at base camp.

However, winter brings exceptionally stable weather and crystalline visibility. Skies are intensely blue, snow-covered peaks gleam brilliantly, trails are nearly empty, and prices drop.

Reality check: you need serious cold-weather gear, high-quality sleeping bags, and mental toughness. Some tea houses close at higher elevations. 

If you’re worrying about the gears and preparation lists, you can either rent or buy here in Kathmandu at affordable prices. We also provide free consultation. Book Now!

Monsoon (June to August) – Wet and Least Predictable

Honestly speaking, monsoon is when we recommend reconsidering your timing. Heavy rainfall creates muddy, slippery trails. Cloud cover obscures mountain views for days. Flight delays become frustratingly common.

That said, monsoon has moments. Landscapes turn incredibly lush. Trails are virtually empty. Prices drop significantly. Everest Base Camp temperature by month varies less during monsoon (10°C to 25°C), but rain and clouds make conditions less pleasant.

Season	Months	Temperature (EBC)	Visibility	Crowd	Best For
Autumn	Sep-Nov	-15°C to 12°C	Excellent	High	Clear views, stable weather
Spring	Mar-May	-10°C to 20°C	Very Good	High	Flowers, warming temps
Winter	Dec-Feb	-25°C to 4°C	Excellent	Very Low	Solitude, clear skies
Monsoon	Jun-Aug	0°C to 25°C	Poor	Very Low	Budget trekking, lush landscapes

Everest Base Camp Trek Weather Month-by-Month

The Everest Base Camp trek offers vastly different experiences each month, with weather shaping not only the physical challenge but also the emotional atmosphere of the journey. Here’s a detailed EBC trek weather by month guide so you know what to expect in every season.

January – Deep Winter and the Coldest Month

January is the coldest month on the trek. Temperatures during the day range from about -17°C to 4°C, but at night they can drop as low as -25°C at base camp. The air is cold and crisp, and the sky is often clear, giving breathtaking views of the mountains. 

The trail is very quiet because few people want to trek in such freezing weather. Although it feels lonely and tough, the peacefulness of the empty trail creates a deep sense of wonder and accomplishment for those brave enough to go.

February – End of Harsh Winter

February feels a little warmer, with temperatures rising to -15°C to 4°C during the day and -20°C at night. Days get slightly longer, and the weather becomes more stable with mostly sunny skies. 

Trekking in February still requires warm gear, but the quiet trails and sparkling winter landscapes make it worth the effort. The cold air feels fresh, and the stillness of the snowy paths makes you feel connected to the majestic beauty of the mountains.

March – Beginning of Spring Season

March is when spring begins on the Everest Base Camp trek. During this month, the days get warmer, usually between -12°C and 7°C, while nights stay cold around -15°C. The lower parts of the trail start to turn green again, and you’ll see rhododendron flowers blooming along the way. 

Although the weather can still be unpredictable, with snowstorms possible, the mix of the last cold days of winter and the fresh warmth of spring feels exciting. The days become longer and the colors of nature lift your mood, making it feel like the whole area is waking up from its winter sleep. It’s a time of new beginnings and hope on the trek.​

April – One of the Best Months to Trek

April is one of the best months for trekking. Daytime temperatures are comfortable, between -5°C to 10°C, and night temperatures drop to about -10°C. The skies are mostly clear, making it easy to see the mountains in all their glory. The blooming rhododendrons add color everywhere. 

April brings longer daylight hours and fully open tea houses. However, the increased number of trekkers means the trails and viewpoints can feel busy, but the beauty and good weather make it a popular and joyful time to be on the trail.

May – Warmer Days and Clear Mornings

May offers the warmest weather before the monsoon. During the day, temperatures range from 0°C to 15°C, with nights around -5 5°C. Mornings are often clear with amazing views, but afternoon clouds build and rain can start by late May. 

The humidity also rises, making the lower sections feel hot. There are fewer trekkers than in April, and the longer daylight hours give you more time to explore. May strikes a balance between warmth and the approaching wet season, keeping many trekkers hopeful and energized.

June – Start of Monsoon

June marks the beginning of the monsoon. Rain starts to fall more often, and temperatures remain between 0°C-15°C. The trail becomes wet and muddy, making walking harder and slower. Lower elevation sections become slippery, and leeches are common. 

Flights to Lukla get delayed frequently because of the weather. Despite the heavy rain, the forests and waterfalls look stunning and vibrant. Trekkers willing to face the challenges during this season experience raw and lush mountain landscapes in relative solitude.

July – Peak of Monsoon

July is the wettest month of the year. It rains nearly every day, and the trail can be dangerous due to mudslides and landslides. Temperatures are mild, but the dampness chills you through. The thick cloud cover often hides the mountain peaks, so views are rare. 

This month is only for the most adventurous and prepared trekkers who enjoy solitude amidst the power of nature. The feeling here is intense: every step is a test of patience and strength against the wet and wild conditions.

August – Late Monsoon with Improving Weather

August still has rain, but it starts to lessen toward the end of the month. The landscape remains green and refreshing, but the trails are often muddy. Temperatures range from 2°C to 16°C during the day and cool off at night. 

You need to be flexible with your plans as the weather can change quickly. The few trekkers in August often appreciate the peacefulness and the fresh new growth in the forests.

September – Post-Monsoon and Clear Skies Return

September is the beginning of the post-monsoon season and brings big changes. The rain stops, the air clears, and mountains reveal their beauty in bright, sharp detail. 

Daytime temperatures are comfortable, generally between 2°C and 15°C. Nights are cooler but not freezing. September feels hopeful and alive, as the trail fills with more trekkers returning for the clearer skies and better weather.

October – Best Weather for Everest Base Camp Trek

October is the best month for the Everest Base Camp trek. The weather is stable, the sky is almost always clear, and temperatures range from -12°C to 12°C during the day and from -10°C to -6°C at night. This month offers spectacular views and great hiking conditions. 

However, it is also the busiest time, so expect crowded trails and fully booked tea houses. Despite the busyness, October feels vibrant and exhilarating, as thousands come to marvel at the mountain’s glory.

November – Cold, Dry, and Sharp Visibility

November keeps many of October’s great qualities but brings colder temperatures. Days range from -15°C to 10°C, and nights can drop from -20°C to -10°C. There are fewer trekkers now, so the trail is quieter. Early snowfalls may start here, adding magic to the landscape but also reminding you that winter is close. The feeling is peaceful but also a little brisk and serious as the high season winds down.

December – Early Winter and Quiet Trails

December introduces early winter and some of the toughest conditions on the trek. Day temperatures range from -20°C to 4°C, with nights plunging to -25°C. You will see more snow, and many tea houses will close for the season. 

The days are short, and the cold cuts sharply, but the trail is quiet and the views, when skies are clear, are breathtaking. December is for trekkers who love solitude and are well-prepared for harsh mountain weather. Every step in this month feels part of a thrilling, life-changing adventure.

• Summer/Monsoon: -5°C to 5°C

• Winter: -20°C to -25°C

Monsoon (June–August): Waterproof jackets and trousers, breathable layers, quick-dry clothes, gaiters, and waterproof trekking boots.

Winter (December–February): Thermal base layers, insulated mid-layers, down jackets, warm hats and gloves, insulated boots, and a sleeping bag rated -25°C. Layering is essential to handle extreme temperature variations.

Are tea houses open in winter and monsoon seasons?

Some tea houses stay open at lower elevations during winter and monsoon, but many higher-elevation ones close. Always check in advance and plan for alternatives.
