Best Time to Trek to Everest Base Camp in 2026: An Honest Month-by-Month Guide

Written by Shreejan Simkhada, CEO of The Everest Holiday and third-generation Himalayan guide. TAAN Member #1586.

Last updated 6 September 2026. Based on running Everest treks every season since 2016, and on what the last few autumns and springs actually did rather than what the brochures promise.

The single most common question I get, ahead of cost and ahead of difficulty, is when to go. It matters more on Everest than almost anywhere, because the difference between the right week and the wrong one is the difference between clear dawns over Ama Dablam and five days of cloud with a flight you cannot get out of Lukla. This is my honest month-by-month answer, including the parts most sites leave out because they are inconvenient.

The short answer

The two best windows to trek to Everest Base Camp are October and March to April. October gives you the most reliable weather of the year and the busiest trail. Spring gives you warmer days, rhododendron forests in bloom, and slightly hazier afternoons. If you want the clear skies of autumn without the crowds, aim for mid-November into early December: colder nights, emptier lodges, and often better value. Avoid the monsoon from June to mid-September, and only go in the deep winter of January and February if cold and solitude are the point. The rest of this page is the detail behind that.

Everest Base Camp month by month

October or November: which is better?

This is the real decision for most autumn trekkers, so let me be plain. October is the safest bet for weather and the reason it is peak season, but it is genuinely crowded. The teahouses fill, the Lukla flights are under pressure, and Base Camp on a clear October morning has a queue of people at the sign. If your dates are fixed to October, book everything early and expect company.

Mid-November onward, the crowds thin out fast while the skies stay clear. The trade is temperature: nights at Gorak Shep drop well below freezing, often to minus ten or colder. That is entirely manageable with the right kit, and the down jacket and the minus-fifteen sleeping bag come free with us, so the cold is a comfort question, not a cost one. For a first-timer who wants the views without the scrum, the second half of November is my honest favourite, and early December still holds before the deep cold sets in.

The cyclone risk nobody mentions

Here is the inconvenient part. Two of the last few autumns have seen the tail of a Bay of Bengal cyclone clip Nepal in the last week of October, bringing a few days of heavy snow and cloud high up and grounding Lukla flights. It is not every year, and it is not a reason to avoid October, but it is real and most operators will not put it in writing. My practical advice: if your dates are flexible, the first half of November has quietly become the steadier choice, and whenever you go, build a spare day or two into the end of your trip so a weather hold turns into a rest day instead of a missed flight home.

What about spring?

Spring, roughly mid-March to late April, is the second season and a wonderful one. The days are warmer than autumn, the rhododendron forests below Namche are in full colour, and this is when the Everest expedition teams are on the mountain, so Base Camp itself is a busy, colourful tent city rather than an empty stretch of moraine. The one honest caveat is haze: as spring warms up, afternoons cloud over and the long valley views can soften, so the clearest photographs are usually taken early in the morning. May is the warmest walking of the year but the most prone to afternoon haze and the first pre-monsoon build-up.

The months to avoid, and the honest exception

June to mid-September is the monsoon. It rains, the trail is slippery and leech-ridden lower down, the big views hide behind cloud for days, and Lukla flights are delayed or cancelled more often than not. For Everest, do not plan a monsoon trek. The honest exception is that the rain-shadow regions on the far side of the Himalaya, Upper Mustang and Dolpo, are actually good in the monsoon because the mountains block the rain, but that is a different trip in a different part of the country, not the Khumbu.

The Manthali diversion, which changes your travel days

This is the operational detail that catches people out, and we tell every client before they book. For roughly the peak weeks, from late September to the end of November in autumn and again from mid-March to mid-May in spring, fixed-wing Lukla flights do not leave from Kathmandu. They leave from Manthali airstrip, which is a four to five hour drive from Kathmandu with a one to two in the morning pickup. It is not a scam or a surprise fee, it is simply how the traffic is managed in the busy seasons, but it means your travel day is longer than you think and you should plan for it. Helicopters are exempt and fly Kathmandu to Lukla direct year-round, which is one of the things you are paying for on the luxury tier of the trek.

Does the season change what it costs?

Our trek price is the same whatever month you book; we do not charge a peak-season premium on the package. What the season quietly changes is the cost around the trek. In October and April, Kathmandu hotels and flights into Nepal are at their most expensive and their most booked, so book those early. In late November, December and the shoulder weeks, the same hotels are cheaper and easier. If you are watching the budget, the quieter months save you money on everything except the trek itself. The full breakdown of what a trek costs, and what sits under everyone's pricing, is in what Everest Base Camp really costs.

Which itinerary suits which season?

The classic twelve-day Everest Base Camp trek works in every open season and is the right choice for most people. Two variations are worth knowing about depending on when you go. If you are travelling in peak October and the crowds put you off, the Everest Base Camp with Gokyo Lakes via Cho La route carries about a fifth of the traffic of the main corridor and gives you turquoise lakes the standard trek never sees. If you have the time and the legs for it, the Everest Three Passes circuit is at its best in stable October and clear late November, when the high passes are least likely to be blocked by fresh snow.

How the weather actually feels, day to day

Averages hide the thing that matters, which is that a single trekking day swings from warm sun at midday to hard frost at night, and the higher you climb the wider that swing gets. Rather than repeat the monthly averages here, I keep a separate guide to what the temperature actually feels like month by month, with the real overnight lows at each stop, so you can pack for the trip you are taking rather than for a number on a chart. If you are choosing between Everest and elsewhere in Nepal for a given month, the best time to trek in Nepal guide covers the whole country season by season.

Is the trail open right now?

As I write this, the Everest region is open and running normally. The flash floods of late August 2026 hit the districts on the other side of the country, along the Bhote Koshi and Trishuli rivers, and did not touch the Khumbu. I keep a trail-by-trail status page current at which treks are open after the Rasuwa flood, so you can check the live picture rather than take a blog's word for it.

So when should you actually go?

If you want one recommendation and nothing else: aim for the first half of November. You keep October's clear skies, you miss the worst of the crowds and the late-October cyclone window, the lodges are easier, and the surrounding costs come down. If November does not fit, October is the reliable classic and April is the beautiful spring alternative. Whatever you choose, tell me your dates and I will tell you honestly what that week tends to do, including the years it went wrong.

Common questions about timing

What is the single best month? October for reliability, or the first half of November if you want the same skies with fewer people and lower surrounding costs.

Can I trek to Everest Base Camp in winter? Yes, in December through February the skies are often superb and the trail is empty, but the nights are severe and some of the highest lodges close. It is a trip for people who genuinely want the cold and the solitude, not a first choice for a first-timer.

Is the monsoon really that bad for Everest? For the Khumbu, yes. Cloud hides the views for days and Lukla flights are unreliable. Save the monsoon months for the rain-shadow treks in Mustang or Dolpo instead.

How far ahead should I book? For October and April, three to six months for the best flights and hotels. For the quieter months you have more room, but the trek itself is worth locking in once your dates are firm.

Will bad weather ruin my trek? A single bad day rarely does; a tight schedule with no spare day is what turns weather into a missed flight home. Build in a buffer day and most weather becomes a story rather than a problem.
