Hoʻolālā a ʻO Everest Base Camp huakaʻi means preparing for much more than cold weather. Weather can vary dramatically with altitude, and conditions can change a lot during the day. A sunny morning can be warm and pleasant, but it can chill out in the evening when the sun sets.
Also, temperatures at Base Camp on Everest vary by season. Conditions are more stable in spring and autumn; winter is extremely cold, and the summer monsoon season often brings clouds, rain, and reduced visibility. March to May and October to November are key trekking periods, while June to September is affected by monsoon weather.
The exact elevation of Everest Base Camp (5380 m / 17,650 ft) varies slightly by source.
The temperatures listed are approximate planning temperatures and not a forecast. Conditions vary from year to year.

The above figures are approximate averages of the Everest Base Camp climate tables as published. Weather can vary by exact location, altitude, day, and year, so figures differ.
No ke aha i anu ai ke kahua hoʻomoana ʻo Everest?
It’s mostly because of altitude. In Nepal, the average temperature drops about 6°C for every 1,000 m (3,281 ft) increase in elevation.
The Everest Base Camp route also descends from the warmer lower valleys to a high alpine area. Namche Bazaar is around 3,500 m (11,483 ft), while Kala Patthar hiki i kahi o 5,545 m (18,192 ft).
This is because temperatures in Lukla may differ significantly from those at Base Camp.
Another important factor is the difference between daytime and nighttime temperatures. When the sun is shining, a chilly morning may feel quite pleasant while you are out walking. After the sun sets, temperatures can drop rapidly.

Higher areas of the path may still have snow and ice. In winter, some accommodation and services may be limited.
Warm clothes and an appropriate sleeping bag are necessary for those who go in January.

Pepeluali: Anu akā Hoʻomaikaʻi mālie
February stays cold, especially at night. Gradually better weather sets in during the day; however, in higher areas, snow and freezing temperatures are still possible.
ʻO Pepeluali ka lua o ka mahina o ka hoʻoilo, akā ʻoi aku ka ʻoluʻolu ma mua o Ianuali ma nā wahi haʻahaʻa; ma nā wahi kiʻekiʻe, manaʻo ʻia nā kūlana hoʻoilo.
A quality down jacket, thermal layers, gloves, and warm sleeping gear are important.
Malaki: Hoʻomaka ka hoʻoilo e hāʻawi i ke ala i ka pūnāwai
The trekking season starts in March. Days start to warm up, and walking during the day becomes easier.
Even at Base Camp, nights can drop below -10°C (14°F), especially early in the month. Snow is still possible at higher elevations.
Ke hoʻomaka nei nā pūnāwai e puka mai ma nā ʻāpana haʻahaʻa o ke ala; ua paʻa nā wahi kiʻekiʻe i ke ʻano alpine.

ʻApelila: He Mahina Kaulana no ka Hiking
The Everest Base Camp trek is a relatively comfortable month in April. Daytime temperatures ease up, but it will still be cold at high altitudes.
He anu nō nā kakahiaka a me nā ahiahi, ʻoiai a puni ʻO Gorak Shep and Base Camp. However, when it is sunny and you are walking, many trekkers feel comfortable during the day.
In the lower parts of the Everest region, spring is also the time of rhododendron flowers. March to May are among the main seasons for visiting Sagarmatha National Park.
Mei: Nā lā mahana ma mua o ka Monsoon
ʻOi aku ka mehana o Mei ma mua o ʻApelila. Hiki ke lilo i mahana hele wāwae ʻoluʻolu i ke ao, akā ʻaʻole mehana loa i ka pō.
The first half of May is more ideal for trekking as moisture and clouds slowly creep up as the monsoon sets in.
As the month draws to a close, the sky may become cloudier, so you may need a little flexibility in your plans.
Iune: Mehana akā pulu nui
ʻO Iune ka hoʻomaka ʻana o nā monsoon ma Nepal. He mālie ke aniau no ka hapa nui o ka makahiki, ʻoiai ʻoi aku ka nui o nā lā ua a me nā ao.
Some parts of the route may receive much more rain than the higher areas. Clouds can obscure mountain views, and trails can be soggy and slippery.
Cloudy skies and poor visibility in the region can also make flights to and from Lukla less predictable.
Iulai: ʻO ka Monsoon ma kona piko
July’s usually one of Nepal’s wettest months. In Nepal, about 80% of annual rainfall falls during the monsoon season, from June to September.
ʻOi aku ka liʻiliʻi o ka ua a me ke ao o ka pūnāwai a me ke kau hāʻule ma mua o ka wā ma mua ʻāina ʻo Everest. Lower areas will be wetter, and even higher areas may not warm up.

If you opt for August, pack waterproof clothing and allow extra time for travel and trail conditions.
Kepakemapa: Hoʻololi i ka Hāʻulelau
September is a transition month. There are still chances of monsoon rain early in the month; toward the end, the weather may be more settled.
As the monsoon wanes, visibility is usually better. As fall arrives, so do the temperatures.
September can be very different toward the end of the month than at the beginning, especially in terms of cloud cover and how wet the trails are.
ʻOkakopa: Anuanu, Maloʻo a Moakaka
Ua manaʻo ʻia ʻo ʻOkakopa he mahina hele wāwae nui ma ka ʻāina ʻo Everest. ʻO ʻOkakopa a me Nowemapa kekahi manawa koʻikoʻi o ka makahiki ma Sagarmatha National Park.
The monsoon has mostly withdrawn, and skies are clearer, with drier trails. The temperatures during the day are cool, not warm and at higher elevations, nights are cold.
If you prefer clear mountain views, October is a month worth considering.
The only downside is that the trail is popular and can get congested, especially around Namche Bazaar and the higher settlements.
Nowemapa: Anu akā maloʻo ma ke ʻano laulā
The dry autumn continues in November, but it gets much colder, especially later in the month.
It is pleasant to walk during the day in sunshine, but mornings and evenings are cold. High elevation areas can experience temperatures well below freezing.
Hāʻawi ʻo Nowemapa i ka ʻike maikaʻi loa ma muli o ke ʻano maloʻo a hiki ke lilo i manawa hoihoi loa e hele wāwae ai no ka mea ʻoi aku ka anuanu o ke aniau a akāka pinepine.
Kekemapa: Hoʻi mai ka Hoʻoilo
Winter is now in the offing, and December is the first month of the colder season. High-elevation daytime temperatures remain cool, and overnight temperatures can be very cold.
Slight snowfall is possible on higher sections of the route. With the onset of winter, fewer trekkers are on the trail.
When planning a trip for December, make sure your travel plans, lodging, and transportation can accommodate changing weather.
Pehea e loli ai ka mahana ma ke ala hele wāwae
The monthly average temperature of Everest Base Camp gives you a helpful overview of what to expect at your destination, but it doesn’t reflect the entire trek.
Eia kekahi laʻana, aia ʻo Lukla ma kahi o 2,860 m (9,383 ft), ʻoiai ʻo Namche Bazaar ma kahi o 3,500 m (11,483 ft). Aia ʻo Everest Base Camp ma kahi o 5,380 m (17,650 ft).
Generally, temperatures decrease as you ascend.
That’s why it is better to pack for multiple climatic zones than to “take a chance” on the weather being uniform along the route.

Your clothing system should consist of layers you can add or remove depending on the temperature.

The cold at Everest Base Camp is one aspect of the weather situation. The weather also plays a part in the trekking experience as it can be affected by both wind and snowfall, by cloud and by rain, or by a combination of these elements, as well as visibility and altitude.
ʻO ke kiʻekiʻe o ka hoihoi. Ke aʻo aku nei ka Papa Hoʻokipa ʻo Nepal e hoʻomaha no ka hoʻomaʻamaʻa ʻana ma ka ʻāina ʻo Everest no ka mea hiki ke piʻi i nā pali.
Itineraries generally include acclimatization days, which you should not skip.

hope aipoalani
The month-wise temperatures at the base of Everest help you decide when to trek and what to pack. The lowest temperature is in the winter, and there is the possibility of snow during this season; the spring has gradually warmer weather; the summer is impacted by monsoon weather; and the autumn has generally cooler and drier weather.
Temperatures vary throughout the Everest Base Camp trek. The weather changes from day to night, season to season, and with rising and falling elevations – and with the presence or absence of sunshine or wind. The figures presented in this guide are for planning and should not be interpreted as a definitive prediction.
Many trekkers plan their trips to coincide with the main spring and autumn seasons, when the weather is generally more agreeable for both trail and visibility conditions and temperatures. It’s always a good idea to check the mountain forecasts just before you go anywhere.
