Best Time to Trek to Everest Base Camp in Nepal

06/Jun/2026

Most trekkers planning to visit Everest Base Camp at 5,364 meters already know that spring and autumn are the go-to seasons.

What they are less sure about is which specific months suit their goals, how the two peak seasons actually compare on the trail, and whether their planned dates will survive Lukla flights. That is exactly what this guide is here to tell you!

Our team at Everest Trekking Routes has guided trekkers through every season and every month on this route. So below, we will give you a clear, honest breakdown of the best time to trek to Everest Base Camp. It will feature weather data, a month-by-month guide, and recommendations based on the type of trekker you are!

Quick Answer: What Is the Best Time to Trek to Everest Base Camp?

As mentioned earlier, the best time to visit Everest Base Camp are the following times:

Spring (March to May)
Autumn (September to November)

Both seasons and all those months offer clear skies, stable trails, and reliable teahouse access through the Khumbu Valley.

However, if you need a single best month, October is the answer. Post-monsoon skies are at their annual clearest, daytime temperatures at Namche Bazaar (3,440 m) stay around 10°C to 15°C. Also, Lukla flights are most consistent during this window!

April is the strongest spring alternative, with warmer temperatures and the rare atmosphere of Everest expedition teams at Base Camp.

For those who want fewer people on the trail, late November and early March are the most practical shoulder options. Both deliver good conditions with noticeably smaller crowds than peak October.

Everest Base Camp Trekking Seasons at a Glance

Before diving into the details, let us give you a quick summary of what each season actually delivers:

Season	Months	Weather	Crowds	Suitability
Spring	March to May	Clear, gradually warming	High	Suitable for first-timers and photographers
Monsoon	June to August	Frequent rain, poor visibility	Very low	Experienced trekkers only
Autumn	September to November	Post-monsoon clarity	Very high	Best visibility of the year
Winter	December to February	Extreme cold, possible snow	Very low	Experienced, fully equipped trekkers

Key Factors That Affect the Best Time to Trek

Weather, temperature, and many other factors can shift which month makes the most sense for your specific EBC trip.

Lukla flight reliability matters more than most trekkers expect! October has the strongest reliability record, with roughly 1 in 10 departures experiencing a delay over 2 hours.

In peak spring and autumn seasons, all Lukla flights route through Manthali Airport in Ramechhap. That adds a 4 to 5 hour early-morning drive from Kathmandu. So, building at least 2 buffer days before any onward international connection is highly recommended.

Accommodation availability is a real constraint in October. Teahouses at Lobuche and Gorak Shep fill by early afternoon in peak weeks. Book ahead for those two nights specifically.

Personal cold tolerance also deserves consideration. If you find cold temperatures genuinely challenging, April’s warmer conditions make altitude acclimatisation slightly more manageable than late November.

Everest Base Camp Temperature by Season

Temperature at EBC (5,364 m) shifts dramatically across the year. Wind chill at exposed sections above Gorak Shep can push these figures lower, especially from October onwards:

Month	Namche Daytime	EBC Daytime	EBC Night
March	5°C to 10°C	−5°C to −2°C	−15°C
April	10°C to 15°C	0°C to 5°C	−10°C
May	12°C to 18°C	5°C to 10°C	−5°C
June to August	12°C to 20°C	8°C to 12°C	0°C
September	10°C to 15°C	2°C to 8°C	−8°C
October	10°C to 15°C	−2°C to 5°C	−12°C
November	5°C to 10°C	−8°C to 0°C	−18°C
December to February	−5°C to 3°C	−15°C to −8°C	−25°C

Everest Base Camp Trek in Spring (March to May)

Spring is the second busiest trekking season, and for many first-timers it turns out to be the preferred one. The weather warms steadily from March, with April offering the best balance of clear skies and comfortable temperatures on the entire trek calendar.

Moreover, rhododendron forests below 3,000 m bloom visibly through April, adding colour to the lower trail sections between Phakding and Namche.

The defining feature of spring is the Everest climbing season. From April through May, international expedition teams set up at Base Camp, preparing for summit attempts. Walking through that environment, past Sherpa climbing crews and expedition logistics, creates an atmosphere that autumn simply cannot offer!

However, May demands careful planning. Pre-monsoon clouds build in the afternoons from around mid-May, and Lukla flight reliability drops noticeably after the 20th. So, you may even have to count on the roadway.

During peak spring season, all Lukla flights operate from Manthali Airport in Ramechhap. That adds a 4 to 5 hour drive from Kathmandu. So, always allow at least 2 buffer days before any onward international connection.

Everest Base Camp Trek in Monsoon (June to August)

Monsoon conditions make the EBC trek significantly harder than other seasons. Rain is frequent below 3,500 m and trails become slippery throughout.

Leeches are also active on the lower forested sections between Lukla and Phakding. Furthermore, persistent cloud cover blocks mountain views for much of the day.

Lukla flights face cancellation rates exceeding 60% during this period!

That said, some experienced trekkers choose monsoon intentionally. Crowds essentially disappear, teahouses are quiet, and the landscape turns intensely green from Lukla through to Dingboche.

The trail above Namche also receives less direct rain than the lower valleys, so conditions above Tengboche can clear occasionally.

If you go during monsoon, build extra buffer days for flight delays and accept that summit views will be limited. This is not a season our team at ETR recommends for first-timers!

Everest Base Camp Trek in Autumn (September to November)

Autumn is the peak trekking season on this route, and October is the crown of it!

Post-monsoon skies produce the clearest mountain views of the year. The views from Kala Patthar (5,645 m) and the trail above Lobuche are at their annual best in this window.

The trade-off is crowds. In October, Sagarmatha National Park sees well over 10,000 trekkers. The section between Namche and Tengboche can feel unexpectedly busy on peak travel days.

Teahouses at Lobuche and Gorak Shep fill quickly, so starting each day early and booking ahead matters.

Also, October often coincides with Mani Rimdu, the Buddhist festival at Tengboche Monastery. Timing your Tengboche arrival to overlap with it is absolutely worth planning around!

By late November, crowds thin considerably. However, temperatures drop sharply, and nights at EBC fall below −18°C!

Everest Base Camp Trek in Winter (December to February)

Winter is the most demanding season on this route!

Daytime temperatures at EBC can drop to −15°C, nights at Base Camp altitude reach −25°C or below, and snow accumulates above Gorak Shep. Lukla flights also face occasional fog and icing delays during this period.

Even so, early December offers a quiet and clear experience for experienced trekkers with proper cold-weather gear.

Most teahouses remain open through mid-December. Beyond that point, services reduce significantly and the cold becomes serious (thus adding to altitude sickness risks).

January and February are suitable only for fully equipped trekkers who understand the risks. If you go in these months, make sure your sleeping bag and layering system are rated for at least −25°C.

Spring vs Autumn: Which Season Is Better for Everest Base Camp?

This is the question our team at ETR receives most often from people deciding between the two peak seasons. Both are genuinely excellent, and neither is a wrong choice. The real question is what you are optimising for:

Factor	Spring (March to May)	Autumn (September to November)
Mountain visibility	Good to excellent	Best of the year
Trail temperatures	Warmer	Cooling toward winter
Crowds	High	Very high in October
Lower trail scenery	Rhododendron bloom	Post-monsoon greenery
Unique experience	Everest expedition season at Base Camp	Mani Rimdu festival at Tengboche
Lukla flight reliability	Good	Best (October)

In short: choose spring if warmer conditions and the expedition atmosphere appeal to you. Choose autumn if maximum mountain clarity is your priority.

Everest Base Camp Month-by-Month Breakdown

March

Spring trekking begins in March. EBC daytime temperatures range from −5°C to −2°C, with nights around −15°C.

Mountain visibility of Everest Himalayas is generally good on clear days, though morning haze can reduce it at lower elevations.

Crowds are manageable, and March is one of the quieter months on this route.

April

April is the peak spring month. EBC daytime temperatures reach 0°C to 5°C, and the lower trail is noticeably warmer.

Rhododendrons are in full bloom below 3,000 m, and expedition teams at Base Camp are active.

Mountain visibility is excellent on most days. Crowds are high but still more manageable than October.

May

May is warm but weather-sensitive. EBC daytime temperatures can reach 5°C to 10°C, and summit-season activity at Base Camp peaks in this month.

However, afternoon clouds build from mid-May, and visibility at altitude can reduce. Lukla flight reliability also drops noticeably after the 20th.

June

June is the transition into monsoon. Rain increases on the lower trail, mountain visibility becomes inconsistent, and flight disruptions rise sharply.

July

July is peak monsoon. Persistent rain, slippery lower trails, and heavy cloud cover dominate. Mountain views from upper sections are possible but unreliable. Not recommended for most trekkers.

August

August remains within the monsoon season, though conditions begin improving in the second half.

Some trekkers arrive in late August for the early shoulder into autumn. Trails below Namche are still wet and challenging.

September

September is the late monsoon period. Early September carries residual monsoon effects, but skies begin clearing noticeably by late September. But because of climate change, even late September these years receive heavy rainfall!

Fewer crowds than October, with increasingly good visibility at altitude. A solid option for experienced trekkers willing to accept some early variability.

October

October is the best single month for the EBC trek.

Clear post-monsoon skies, stable daytime temperatures, and the most reliable Lukla flight conditions of the year all align in this window.

Crowds are at their highest. Book teahouses at Lobuche and Gorak Shep in advance.

November

November offers excellent mountain visibility and significantly fewer trekkers than October, particularly after the 20th.

However, temperatures drop sharply. Nights at EBC fall below −10°C by late November, and Lukla can experience fog delays. It’s best that you build two buffer days into your schedule for the return flight!

December

Early December is a quiet, clear window for experiencead trekkers with proper cold-weather gear.

Most teahouses remain open through mid-December. After that point, conditions worsen and services on the upper route reduce.

January

January is the coldest month on the trek calendar. EBC daytime temperatures fall to −15°C or lower, and nights can reach −25°C.

Skies are frequently clear, and views are outstanding on good days. Suitable only for experienced high-altitude trekkers with proper cold-weather equipment.

February

February conditions are similar to January, with a gradual warming toward the end of the month.

Trails are almost completely empty. Clear days bring excellent visibility. Not recommended for beginners or trekkers without prior cold-weather experience at altitude.

Best Time to Trek Everest Base Camp for Different Trekkers

The right season genuinely differs based on what you want from the experience. Here is a practical breakdown based on what we see from the trekkers we guide each year:

First-time trekkers: October or April. Both offer reliable conditions, well-staffed teahouses, and temperatures that do not force difficult gear decisions. Also, the difficulty level is ideal at that time.
Photography-focused trekkers: October and early November, for the sharpest post-monsoon light and clearest views of Everest’s south face.
Crowd avoiders: Late November after the 20th, or early March. Accept colder nights in exchange for quieter trails.
Budget-conscious trekkers: March or May shoulder months, when teahouse prices and availability are more favourable than peak October.
Trekkers wanting the Everest expedition atmosphere: April to early May, when Base Camp is fully active with summit teams.
Experienced trekkers seeking solitude: Early December or late February, with full cold-weather gear and flexible schedules.

Final Verdict: When Should You Trek to Everest Base Camp?

If you are planning to trek to EBC for the first time and want the best overall experience, October is the clear choice. Clear skies, stable weather, and the most reliable logistics of the year come together in that one month.

April is the best spring choice, particularly if Base Camp’s expedition-season energy or warmer trekking temperatures appeal to you. For quieter trails without heavy physical and mental difficulty, late November and early March remain the most practical alternatives.

Avoid deep monsoon and deep winter unless you are experienced, well-equipped, and genuinely flexible with your schedule.
