Introduction
Standing at the base of Mount Everest is a life-changing experience. The mountain towers 8,849 meters into the sky, and seeing it up close is an experience larger than any picture can show. Thousands of trekkers make this journey every year, and every single one of them has a story to tell when they get back.
Choosing the right month will make the experience even better. The weather around the Himalayas changes drastically with the season. The choice of month will impact everything, from the quality of pictures you will take to the number of trekkers you will have to hike with. Some months will have you hiking with hardly any other trekkers, but you will have to deal with cold weather. Others will have you hiking with many other trekkers, but you will have perfect weather.
The hike will take you to 5,364 meters at the base of Mount Everest itself. Many trekkers choose to hike up to Kala Patthar, which is at 5,643 meters and provides the best view of the top of Mount Everest. It will take some time for your body to get accustomed to such high altitudes. The right weather will make it easier for you to acclimate to such high altitudes.
Before you book your flights, you should have the right gear for the climb. Have a look at our Everest Base Camp packing list, so you do not forget anything essential for the high-altitude hike. Having the right gear will make a huge difference between struggling and enjoying every moment of the hike.
The Gold Standard: Autumn (October – November)
The best months to trek to Mount Everest Base Camp are October and November. These months offer a perfect blend of weather. For one, it is during these months that you get the clearest view of your surroundings because of all the rain that has fallen on the mountains over the summer months. Photographers love trekking to Mount Everest during this time because they get to take pictures of razor-sharp mountains against a bright blue sky.
The monsoon rain that falls on the mountains from June to September is actually a blessing in disguise. It washes away all the dust and other particles that float around in the air. Come October, and what is left is what trekkers refer to as "diamond-clear" visibility. Standing on top of Kala Patthar at a height of 5,545 feet, one is able to get a very detailed view of Mount Everest, which is a whopping 8,848 feet above sea level.
The weather is quite chilly in the morning, but it is still very manageable. You get to wake up to a nice layer of frost on the grass, and by lunchtime, it is all nice and warm. Come nightfall, it does get quite cold, with temperatures dipping well below freezing point.
The weather is more important than one thinks. For one, stable weather means that there will be fewer canceled flights at Lukla, a small airport nestled at the foot of Mount Everest that serves as your point of entry into the mountains. Stable weather means that you get to enjoy your trek without any clouds interrupting your view at sunrise. Stable weather means that your well-laid plans come to fruition.
The only downside to trekking to Mount Everest during October is that it is the best month to trek to Mount Everest. Be prepared to be surrounded by fellow trekkers from all over the world.
While October is the best month to trek to Mount Everest because of the view, it is still a very challenging trek. Understanding EBC trek difficulty is a big help when it comes to training properly so that one is able to enjoy the view without gasping for breath every five steps.
The Climber's Window: Spring (April – May)
Spring at Everest Base Camp brings the mountains back to life. The lower parts of the trail are in full bloom as the rhododendrons display their colors in shades of pink, red, and white. Nepal's national flower creates a striking contrast with the white peaks in the background.
Hiking to Everest Base Camp in April and May feels like entering a temporary city. Hundreds of colorful tents are scattered all over the rocky terrain as climbers from all over the world converge at Everest Base Camp, preparing for their summit attempt. You will see top mountaineers training, testing their gear, and swapping stories and cups of tea. The atmosphere is electric and highly contagious.
Spring at Everest Base Camp offers a significant temperature increase compared to autumn. Days feel like they are approachingcomfort levels, especially at lower elevations. Spring is a favorite among trekkers who don't like extreme cold. Nights are still cold at the high camps, although not as brutally cold as in October and November.
The downside of spring at Everest Base Camp is the afternoon clouds that roll in during this season. Spring weather at Everest Base Camp follows a predictable pattern: mornings are usually clear and breathtakingly beautiful, while afternoons and late afternoons are shrouded in a thick mist that usually rolls in around 2:00 PM. Smart trekkers wake up early and enjoy the sunrise and the beauty of the mountains before the mist rolls in.
The spring climbing season has its own special magic. You may sit at a lodge and have breakfast with climbers who have just come back from the Khumbu Icefall. You will see helicopter rescues, hear stories of summit success and failure, and feel a connection with Everest's climbing history that cannot be experienced during any other season.
Since the trails are crowded during this season and a proven Everest Base Camp itinerary has a specific schedule, following a tried-and-tested Everest Base Camp Itinerary allows you to avoid rushing the changes in altitude while enjoying the best spots for photography and Everest's mountain culture.
Month-by-Month Weather Guide for 2026
Choosing the right month isn't just about the view. Your body also has a vested interest in the temperature, and understanding what to expect will ensure you bring the right clothing for the extreme temperature fluctuations between day and night.
Every 1,000 meters in altitude means a temperature drop of 6.5 degrees Celsius. The difference this makes at Everest Base Camp (5,364 meters) is huge. A pleasant 15 degrees Celsius day in Namche Bazaar (3,440 meters) will be much colder at higher altitudes.

Don't let the warm days fool you. When the sun goes behind the mountains, the temperature drops fast at 5,364 meters. In May, you'll need a water bottle that freezes overnight. The temperature fluctuations are a shocker. You may walk in a t-shirt in the daytime and need all your clothing within three hours of walking when the sun disappears behind the mountains. This extreme change in temperature requires intelligent packing. You'll need clothing that can be used in layers instead of heavy clothing.
If you don't like extreme cold, May offers the best temperatures. If you want no crowds, February offers clear skies with a heavy-duty sleeping bag. March and April offer a good compromise with temperatures rising enough to make nights much easier to handle than January's deep freeze.
Knowing how temperature behaves helps you pack the right gear. A good down jacket will suffice in October and November. Winter months require expedition gear with a sleeping bag rated below -20 degrees Celsius. Spring requires less gear than autumn, but still requires warm clothing because of early morning and evening temperatures.
Cold air tends to be dry air. This can cause dehydration and increase the risk of altitude sickness. Make sure you read our altitude sickness prevention tips to understand how temperature and altitude work together that helps you prepare your body for the challenge.
The Quiet Months: Winter and Monsoon
The crowds may be out in full force in October, but there’s an alternate version of the Himalayas in the off-season: one that’s untouched, quiet, and very personal. You just need to deal with some tough challenges first.
Winter Reality (December-February)
The winter season provides the best photography opportunities of the year. There’s virtually no moisture in the air, making mountains look incredibly crisp and clear. Every ridge, every rock face, and every patch of snow looks like it’s in perfect focus.
But be prepared for temperatures as low as -25 degrees C or lower at Base Camp. That’s cold enough to freeze water bottles inside your sleeping tent. Many of the high-altitude tea houses shut down completely during winter, as it’s impossible to keep the pipes from freezing. The ones that stay open charge premium rates.
You’ll need some heavy-duty gear for the cold: a sleeping bag rated for -30 degrees C, a down jacket, insulated pants, and good boots. Your regular trekking gear won’t be enough for January.
The flights to Lukla operate during winter, but be aware that morning flights out of Lukla may be delayed if there’s frost on the runway.
Monsoon Reality (June-August)
Summer means rain, lots of rain. The lower areas of the trail will be lush green with plants flourishing with growth. Wildflowers will be ubiquitous, as will waterfalls cascading down mountain faces. It will be like a botanical garden.
The downside is that rain will fall every afternoon, making the trails muddy and slippery. Leeches will appear on the lower areas, attaching themselves to your boots or skin. Clouds will be the norm, hiding mountain vistas most days. Flights to Lukla will be cancelled frequently due to pilots being unable to see the short airstrip through thick fog.
Base Camp will be surprisingly dry as it is in a rain shadow, but reaching there will mean crossing through the wet lower areas. You'll spend days walking through clouds, not enjoying the scenery.
Who Should Trek Off-Season?
For the hardy solitude seeker, winter is the best time. You'll have to have experience with winter camping and have the right gear. But the reward is having the most famous trekking route in the world almost to yourself. For the budget traveler, monsoon season is a treat. Prices will be lower at tea houses, guides will give discounts, and everything will be negotiable. You'll have a different experience with the green valleys and flowers, unlike the stark beauty of the other seasons.
Trekking in July? Well, let's be honest, you'll have to deal with leeches and rain clouds, but you'll also have an experience that 90% of all other trekkers will never have. And that, my friend, is something special indeed.
Trekking off-season, as mentioned, carries risks, which include flight cancellations, delays, or closed facilities. Trekking insurance for Nepal is a must, especially when planning to trek the famous Everest Base Camp during these uncertain months.
2026 Essential Planning Tips for Your Trek
Trekking to the base of the world's highest peak is a classic adventure that never goes out of style, yet the logistics of reaching the trekking destination have changed beyond recognition. Failure to plan for new flight rules and guide requirements may cause your trek to come to a complete halt even before your trekking journey begins.
The Reality of Ramechhap Flights
During peak months (October/November and April/May), all flights to Lukla operate from Manthali Airport in Ramechhap instead of Kathmandu. This is to prevent congestion at Lukla airport, yet it means that you will have to drive 4 to 5 hours from the capital city.
Most trekking agencies offer shared vans that leave Kathmandu at around 1:00 AM. You will arrive at Ramechhap just in time to catch your early morning flights. The flights take only 18 minutes, giving you a bird's-eye view of the beautiful hillsides and snow-capped mountains. Be sure to carry snacks and games to keep yourself entertained during the long drive. Once you arrive at Ramechhap, check-in is quick because it is a small airport that mainly serves mountain flights.
Digital Trail: e-SIM
Skip the SIM card queues at Kathmandu airport. In 2026, you can purchase a Nepal Telecom (NTC) or Ncell e-SIM online prior to departure from home. These offer reliable 4G/LTE coverage even in remote mountain villages such as Gorak Shep.
The Guide Mandate
The Nepalese Government has implemented a "no solo trekking" policy in Sagarmatha National Park. In order to pass through the checkpoints, you are required to hire a licensed guide and trekking agency. Government officials at the entrances of the national park scrutinize the documents of trekkers.
This policy has been implemented to protect the lives of trekkers and provide employment to local guides. Your guide will assist you in identifying altitude sickness, navigating through bad weather conditions, making bookings in tea houses, and explaining local culture. In fact, most trekkers agree that having a guide enhances their experience substantially.
Please ensure that the guide you hire has proper TAAN certification from the Trekking Agencies' Association of Nepal. Also, make sure that the guide presents a proper license prior to making any contract.
Although flights and permits are a logistical necessity, accommodation choices are a make-or-break factor in recharging your batteries after a long day of trekking. Finding the best tea houses on EBC trail ensures that you have comfortable places to rest and relax with fellow trekkers.
Making Your Choice
The choice between crystal-clear skies in October and vibrant life in April boils down to a single fact: at 5,364 meters, you will have a life-changing experience that will stay with you long after the mountain dust is gone from your boots. October is best for photographers and for people who want the clearest possible views. April is best for social trekkers and people who enjoy the excitement and commotion that accompany the climbing season.
For people who want the mountains all to themselves and are willing to brave extreme conditions, the off-season months are best. No time is bad for visiting Everest. Each month offers a unique experience. We have seen people discover magic in December as much as they have in May. Your story is what determines your best month.
Your fitness levels also determine your best month for trekking to Everest. If you are extremely fit and can handle extreme cold, then you can trek in the winter. If you like temperatures that are neither too hot nor too cold and do not like afternoon cloud cover, then spring is your best time for a trek. If you want the clearest possible views and do not mind sharing your experience with others, then October is your best month for trekking to Everest.
What do you want most? Do you want to have the mountains all to yourself, or are you comfortable sharing your experience with others? Can you handle minus 20-degree temperatures at night and still enjoy your trek? Do you want temperatures that are a little higher, and do not like afternoon cloud cover? Do you want clear mornings and do not mind cloud cover in the afternoon? Your answers to these questions will help you choose your best month for trekking to Everest and having a life-changing experience that will stay with you forever.
