Trekking to Everest Base Camp in December means cold mornings, clear skies, and some of the quietest trails you’ll find all year. At Everest Hikes Pvt. Ltd., we send trekkers into the Khumbu region every winter, and December is one of our favorite months to talk people through, because it rewards preparation and punishes shortcuts. This guide covers everything you need: weather, snow conditions, Lukla flights, gear, permits, and honest answers about what the trek is really like in winter.
Is December a Good Month for the Everest Base Camp Trek?
December works well for trekkers who want clear mountain views and don’t mind cold temperatures. Rain is rare, visibility is often excellent, and the trails carry far fewer crowds than October or November. The trade-off is the cold, especially at night, and the chance that snow will close a section of trail for a day or two.
This is not a beginner’s month. Anyone attempting Everest Base Camp in December should have some cold-weather hiking experience, or at minimum, travel with an experienced local guide who knows how conditions shift as winter sets in.
Who Should Consider This Trek
- Trekkers who prioritize mountain visibility over trail company
- Photographers wanting snow-dusted peaks against clear skies
- Travelers on a Christmas or New Year trip to Nepal
- Budget-conscious trekkers looking for off-season lodge rates
- Anyone who dislikes crowded teahouses and busy trails
Who Should Wait for Another Season
- First-time high-altitude trekkers with no cold-weather experience
- Trekkers hoping to complete the Three Passes or Gokyo Chola route
- Anyone uncomfortable with the possibility of changed plans
December Weather in the Everest Region
Expect daytime temperatures around Namche Bazaar of roughly 7°C (44°F), dropping to about -6°C (21°F) after dark. Higher up, near Base Camp and Kalapatthar, night temperatures fall well below freezing. Days are usually dry, with snow rather than rain falling on the upper trails.
Mornings and evenings are the hardest part of the day. The sun disappears behind the ridgelines early, and temperatures drop fast once it does. Trekkers who layer properly and keep moving during the coldest hours handle this far better than those who wait around in the cold.
December sits between the shoulder season and deep winter. It’s colder than November, but nowhere near as harsh as January or February, which makes it a reasonable middle ground for people determined to trek in winter.
Everest Base Camp Temperature by Location (Approximate)
| Location | Altitude | Day Temp | Night Temp |
|---|---|---|---|
| Namche Bazaar | 3,440m | 7°C / 44°F | -6°C / 21°F |
| Tengboche | 3,860m | 4°C / 39°F | -10°C / 14°F |
| Dingboche | 4,410m | 2°C / 36°F | -13°C / 9°F |
| Lobuche | 4,940m | -1°C / 30°F | -17°C / 1°F |
| Everest Base Camp | 5,364m | -4°C / 25°F | -20°C / -4°F |
These figures shift year to year, so treat them as a planning guide rather than a forecast.
Snow Conditions and Trail Impact
Snowfall becomes more frequent as December progresses, particularly on higher sections of the route. A heavy snowfall rarely lasts more than a day, but it can leave a trail difficult to follow or temporarily blocked until porters and lodge owners clear it.
This is exactly why we recommend hiring a guide for winter treks. Local guides know the terrain well enough to reroute around a blocked section, judge when it’s safe to continue, and communicate with lodges ahead to check trail status before you set out.
Some high passes close entirely once the snow settles in. If your plan includes Cho La, Renjo La, or the Three Passes circuit, check current conditions before committing, and have a backup itinerary ready.
Lukla Flights in December
Lukla flights in December tend to run more reliably than in the monsoon months, since clear, dry mornings are common this time of year. That said, mountain weather changes fast, and delays or reroutes through Manthali (Ramechhap) still happen occasionally.
Build at least one or two buffer days into your schedule before your international departure. A missed connection due to weather is common enough in Everest region trekking that experienced operators plan around it as a matter of course.
Trail Conditions and Visibility
Visibility in December is often better than in the busier autumn season. Clear skies dominate, and the combination of fresh snow on the peaks with blue skies below makes for striking mountain views, especially around Kalapatthar and Everest Base Camp itself.
The trade-off is underfoot conditions. Icy patches form on shaded sections of trail, particularly in the early morning before the sun reaches them. Trekking poles and proper footwear make a real difference here.
Preparing for the Trek
Physical Fitness and Training
Regular cardio training in the months before your trek helps, but nothing fully replicates high-altitude conditions. Hiking with a loaded pack, running, or stair climbing three to four times a week for two months prior is a solid baseline. What matters most on the trail itself is pace, not raw fitness.
Altitude Sickness Prevention
Altitude sickness happens when your body doesn’t get enough time to adjust to lower oxygen levels. It isn’t related to how fit you are; it can affect anyone. Standard itineraries build in acclimatization days at Namche Bazaar and Dingboche for exactly this reason.
Practical steps that help:
- Drink water consistently throughout the day, even when it’s cold
- Eat proper meals at breakfast and dinner, and snack during the day
- Never skip a scheduled acclimatization day, even if you feel strong
- Watch for headaches, nausea, or dizziness, and mention them to your guide early
- Descend if symptoms don’t improve with rest
Packing List for December
Winter packing is less about volume and more about the right layers. A four-season sleeping bag is essential, since teahouse rooms have no heating.
Clothing
- Four-season sleeping bag (rated to at least -15°C)
- Waterproof trekking boots, broken in before the trip
- Waterproof trekking trousers and thermal leggings
- Down jacket plus a mid-layer fleece
- Thermal base layers (top and bottom)
- Warm socks, thin liner gloves, and thick waterproof outer gloves
- Warm hat and a sun hat
- Sunglasses with UV protection
Gear
- Trekking poles
- Headlamp with spare batteries
- Thermal flask for hot drinks
- Water purification tablets or a filtering straw
- Basic first-aid kit with any personal medication
- Power bank, since charging costs extra at teahouses
- Sunscreen and lip balm (winter sun at altitude is still strong)
Permits Required for the Everest Base Camp Trek
Two permits cover most standard routes into Sagarmatha National Park:
- Khumbu Pasang Lhamu Rural Municipality Entrance Permit — approximately NRs 2,000 per person, available in Lukla or Monjo (not in Kathmandu)
- Sagarmatha National Park Entry Permit — approximately NRs 3,000 per person, available at the Nepal Tourism Board in Kathmandu or at the Monjo park gate
Trekkers entering via Jiri also need a Gaurishankar Conservation Area Permit (roughly NRs 3,000), obtainable only in Kathmandu. Bring a passport copy for each permit, plus two passport photos for the Gaurishankar permit.
Route Options and Itinerary Adjustments
The classic Lukla to Everest Base Camp route stays open through most of December, though sections above Dingboche can require rerouting if snowfall is heavy. A trusted guide will know when to hold a rest day versus push forward.
If passes are closed or conditions turn difficult, a shorter loop from Namche to Tengboche and back to Monjo and Lukla still delivers strong mountain views without the higher-altitude risk. Combining a short trek with a helicopter return from Base Camp or Kalapatthar is also popular in December, since flying conditions are usually favorable.
What’s Open and What’s Closed in December
| Feature | December Status |
|---|---|
| Main EBC trail (Lukla–Gorak Shep) | Generally open |
| Cho La / Renjo La passes | Frequently closed |
| Three Passes / Gokyo Chola circuit | Not recommended |
| Himalayan Rescue Association (Pheriche) | Closed |
| Dingboche health clinic | Closed |
| Lodges in Thagnak, Dhonjila, Lungden | Mostly closed |
| Helicopter tours | Generally reliable |
Sherpa Villages and Highlights Along the Way
Namche Bazaar is the heart of the trek’s social side, even in winter. It’s where most trekkers spend their first acclimatization day, and the town stays lively with a handful of open lodges, shops, and a bar or two, even during the quiet season.
- Tengboche Monastery – the highest monastery in the region, where visiting monks and joining a morning puja gives real insight into Sherpa Buddhist culture
- Khumjung village – home to the school and health post Sir Edmund Hillary helped establish, worth the side trip on an acclimatization day
- Hotel Everest View – a short hike from Namche with one of the best panoramic views of Everest in the region
- Tenzing Norgay Sherpa Heritage Centre – opened at the Sagarmatha National Park Visitor Centre, covering the history of early Everest expeditions
- Kalapatthar at sunrise – at 5,545m, this remains the best viewpoint of Everest itself, and December’s clear skies make it worth the early, cold climb
There are no major festivals in the Everest region in December, but trekkers spending Christmas in Namche will usually find a small, informal gathering among foreign visitors and lodge staff.
Accommodation and Food During the Winter Trek
Teahouses along the main route stay open through December, though menus shrink and some smaller lodges close for the season as families head down to lower villages. fRooms are basic: twin beds, thin blankets, and shared bathrooms, which is why your own sleeping bag matters so much this time of year.
Hot showers and device charging usually cost around $3 each. Boiled water is available for purchase at every open teahouse; carrying purification tablets or a filter straw is a cheaper backup, and it’s safer than melting snow yourself.
Hiring a Guide or Porter
Winter is a harder season to find a guide or porter on short notice, since many head to lower altitudes once the main season ends. Booking through an established operator like Everest Hikes Pvt. Ltd. well in advance solves this, and it means you’re paired with someone who has direct winter trekking experience on the exact route you’re taking.
Safety, Insurance, and Emergency Services
Confirm your travel insurance covers trekking up to at least 5,000m before you leave home, and check the fine print on helicopter evacuation. Rescue flights are dispatched only once payment is confirmed, so insurance documentation needs to be accessible, not just purchased.
Health posts thin out in winter. The Himalayan Sherpa Hospital in Phakding stays open year-round with basic outpatient and emergency care. The Mountain Medical Institute clinic in Namche also operates through winter, but its Dingboche location and the Himalayan Rescue Association post in Pheriche both close for the season.
Christmas and New Year Treks to Everest Base Camp
Trekking over Christmas or New Year in the Khumbu has its own appeal: quiet trails, low-key celebrations in Namche, and a genuinely different way to spend the holidays. Just book early, since flights and popular lodges can fill up around these dates despite the overall lower trekker numbers.
