Outdoor weather and climate is pretty normal until the time you are trekking on the lower altitudes of Everest Base Camp. By the time, you reach higher elevations ( EBC), weather starts to be harsh and unpredicted. And if, it’s your dream destination that guarantees all sort of physical challenges to test your potential, adventure skills and mental determination – it’s obvious to expect more erratic climates for sure.
Everest Base Camp Trek Climate Overview
The Everest Base Camp Trek travels through a variety of climatic zones; from the lower sub-tropical regions at the beginning of the trek, to the severe alpine climate near to Everest’s base. Weather conditions and temperatures vary enormously throughout the year and even with altitude, which is why it is so important to familiarize yourself with both seasonality and how best to prepare.
Spring (March to May): Best time for trekking, the temperatures are moderate and the sky is mostly clear. The day temperature at lower altitude work, like Namche Bazaar will be between 10°C to 15°C (50°F to 59°F), where as night falls to -5°C to -10°C (23°F to 14°F). The higher you climb, the colder it gets and also becomes more unpredictable since late mornings can experience snowfall; however, not in Base Camp. During spring, all these beautiful mountains are visible after a long stay of winter’s slumber. The immense beauty of blooming flowers around makes this time more magical.
Autumn (September to November): Like spring, autumn is also known as the best season for Everest Base Camp Trek .The temperatures are mild while days are still warm with plenty of sunshine having temperatures around 15°C – 20°C(59°F-68°F) in lower elevations. Nights start falling into the negatives with an average temperature level below -10 °C (14 °F).
Winter (December to February): December to February is the period referred to as Winter. For trekking, winter is a bit uncomfortable due to the extreme cold. At lower elevations, temperatures during this season range between -5°C and 5°C (23°F and 41°F) but in higher altitudes, it becomes much colder with night temperatures dropping up to -15°C and -25°C (5°F and -13°F).. Snowfall is common, and some tea houses at higher altitudes may be closed. The cold and the risk of avalanches make winter trekking less popular, although some people may be drawn to the peaceful snow-covered landscapes.
Summer (June to August): The summer monsoon season brings heavy rains to Nepal, especially in the lower parts. It can rain nonstop for days, causing trails become muddy and slippery. Temperatures are still warm at lower elevations, around 20°C to 30°C (68°F to 86°F), but it is not advisable trek during this season due high risks of landslides and leeches as well as general discomfort from heavy rain. Additionally, the monsoon clouds often obscure views of the mountains which are one of main highlights of the trek.
Weather Preparation Tips
Layered Clothing: The weather on the Everest Base Camp Trek is variable, with temperatures changing drastically throughout the day and as we gain altitude. Layering your clothing helps you to regulate your body temperature by adding and removing layers of clothing throughout the day and as you hike higher. A wicking base layer to take moisture away from your skin, an insulating middle layer to help retain body heat and an outer shell jacket designed for protection against wind, rain and snow.
Warm Clothing for High Altitudes:As you gain altitude, temperatures can plummet, especially during the evening and night. Therefore, a good quality down jacket is an essential item to keep you warm along with thermal gloves, hat and scarf. Expect temperatures below freezing as you near Everest Base Camp especially during early morning and late evening.
Sun Protection: The sun’s rays are much stronger at high altitudes and the risk of sunburn is greater. Use a high SPF sunscreen on all exposed areas of skin, wear sunglasses with UV protection and apply lip balm that contains sunscreen. A wide-brimmed hat will also help to protect your face.
Waterproof Gear: Rain or snow can occur at any time during a trek so it’s important to be prepared for wet weather conditions. A waterproof jacket and pants are necessary to stay dry during rain or snow fall as well as in wet conditions. A rain cover for your bag is also useful to ensure that contents don’t get soaked.
Weather-Related Risks: Altitude and Cold
Altitude and Weather Conditions: It will get colder and less predictable weather wise the higher up you go. Not only can the temperature drop dramatically especially at the highest points, altitude sickness becomes more of a risk as well. Keep drinking water, eating food, and taking those acclimation days seriously. If you start experiencing an unusual headache or become disoriented head back down immediately.
Frostbite and Hypothermia: The extreme cold in the higher altitudes can lead to frostbite or hypothermia if proper precautions aren’t taken. Wear insulated gloves and socks, and avoid exposing your skin to the cold for extended periods. Ensure that your feet, hands, and face are well-protected from the wind and cold temperatures especially if the weather becomes especially harsh.
Daylight Hours: Because of the high altitude and the angle of the sun, in winter months the daylight hours are much reduced. It’s a good idea to start walking very early so you can finish well before dark as temperatures will plummet quickly and become bitterly cold at night. During Spring and Autumn months there is available light for longer.
Summing Up
Knowing the weather and being prepared for it is key to a safe and successful trek to Everest Base Camp. Opt for the optimal trekking seasons—spring and autumn—for the most predictable and best overall weather. But no matter when you go, expect rapidly changing weather, extremely cold temperatures at higher elevations, and a chance of encountering snow or rain at any time during your journey.
