With dry conditions, steady sunshine, and mild winter air, Christmas in Kathmandu feels pretty balanced for sightseeing and outdoor fun. There’s something about this mix that just sets the right mood for a memorable holiday—it’s really nothing like any other season in the city.
Overview of December Weather in Kathmandu
December in Kathmandu means mild daytime warmth, cooler nights, and almost no rain. The winter season shows up with clear skies and shorter daylight hours, keeping things stable and pretty predictable for outdoor plans.
Typical Temperature Range
Daytime temperatures in Kathmandu usually reach around 17–20°C (63–68°F). Nights, on the other hand, get much cooler, often dropping to 3–8°C (37–46°F).
This shift into winter brings chilly mornings and evenings, but afternoons stay comfortable.
The colder nights mean you should pack a warm layer, especially if you like being outside after sunset. Since most buildings in Nepal don’t have central heating, the difference between day and night feels more intense indoors.
You’ll notice the climate doesn’t swing wildly. Daily highs and lows stay pretty steady, which makes December a reliable month for travel plans.
| Time of Day | Average Temperature |
|---|---|
| Daytime | 17–20°C (63–68°F) |

Precipitation and Rainfall Patterns
December barely brings any rain to Kathmandu. The city gets only about 20–25 mm of rainfall for the whole month, and you might see just 1 day of rain.
Compared to the wild, wet summer monsoon, it’s a huge difference. The dry air makes winter feel more comfortable.
Humidity usually sits between 70–80%, but since rain is rare, the air doesn’t feel muggy. Dry conditions make hiking, sightseeing, and just being outdoors a lot easier.
You could bring a light rain jacket or umbrella, but honestly, you probably won’t need it. The low chance of rain is one of the main reasons people pick December for their Nepal trips.
Hours of Sunshine and Daylight
December brings shorter days to Kathmandu. You get about 10 hours and 20 minutes of daylight, which is the shortest stretch all year.
Even with less daylight, skies are usually clear, so you’ll still enjoy 7–8 hours of sunshine per day.
This mix of short days and bright skies creates ideal conditions for outdoor sightseeing. Mornings start later, evenings arrive earlier, so you might want to plan key activities for midday when the sun feels strongest.
You get about 250+ hours of sunshine during December, which means plenty of bright, crisp days. Sun protection still matters at this altitude, so don’t forget sunglasses, sunscreen, and a hat—even in winter.
Christmas Weather Conditions: What to Expect
Kathmandu during Christmas brings mild days, cool nights, dry air, and mostly clear skies. Rain almost never shows up, and snow in the city? Forget it. But the mountain views—especially in the mornings—can be fantastic.
Daytime and Nighttime Temperatures
Daytime temperatures in December usually land between 15°C and 20°C (59°F to 68°F). That’s perfectly comfortable for walking, sightseeing, or even eating outside. You won’t need a heavy winter coat, but a sweater or light jacket is a good idea.
At night, temperatures drop fast. It often falls between 3°C and 8°C (37°F to 46°F), so evenings and mornings feel chilly. Many hotels have thin walls and limited heating, which makes nights feel colder than you might expect. Warm pajamas and an extra blanket go a long way.
Temperatures don’t change much day-to-day around Christmas, so you can plan your outings for the warmest daylight hours and relax indoors after dark.
Humidity and Wind Levels
Humidity in December usually runs between 70% and 80%, but the air rarely feels damp because rain barely happens. The dryness keeps things crisp and comfortable.
Wind? Not much. Speeds stay very low, usually 0–1 m/s. Days are calm, and you won’t be fighting gusts while you wander the valley.
Since the air stands still, pollution and smoke sometimes hang around in the mornings before the sun burns them off. If you’re sensitive to air quality, tossing a light mask in your bag isn’t a bad idea.
Chances of Snow and Visibility
Snow in Kathmandu during December? It’s almost unheard of. The city sits at about 1,400 meters elevation, which is too low for real snowfall. If you’re dreaming of a white Christmas, you’ll need to head higher into the Himalayas where snowfall is common.
Rain is also pretty unlikely. December averages just 20–25 mm of precipitation, usually squeezed into a single day.
Visibility stays excellent. Clear skies often reveal Himalayan peaks, especially in the early morning. Sure, haze can build up later in the day, but compared to the monsoon, December is one of the best times for mountain views.
How Kathmandu’s Winter Season Affects Travel
Winter in Kathmandu brings cool mornings, mild afternoons, and lots of clear skies. These weather patterns shape when you should visit, how crowded the city feels, and which outdoor activities you’ll actually enjoy.
Best Time to Visit Kathmandu in December
December falls right in the middle of Kathmandu’s winter season, with daytime temperatures averaging 15–18°C (59–64°F) and nighttime lows near 5–7°C (41–45°F). Rain barely makes an appearance, often less than 25 mm for the whole month.
Crisp mornings warm up by the afternoon, so layering is your best bet. A light sweater or jacket is usually enough once the sun goes down.
Low humidity and clear skies mean you get excellent visibility—perfect if you want to trek around the valley or hit up viewpoints.
Since December skips the heavy summer rains and the hazy spring air, it’s honestly one of the best times for sightseeing and walking tours in Kathmandu. The steady weather makes planning so much easier.
Crowds and Local Festivities
Winter brings fewer international tourists than autumn, so you’ll probably find smaller crowds at spots like Swayambhunath, Pashupatinath, and Bhaktapur Durbar Square. If you like quieter travel, December might be your sweet spot.
But local life doesn’t slow down. December features several cultural events and religious festivals, like Tamu Lhosar, the Gurung New Year. Expect lively gatherings, traditional dances, and special foods during the celebration.
Shops and markets stay active as people prep for festivals. You get to see daily life in the valley at a slower, more relaxed pace compared to the tourist-packed months. Even with fewer visitors, the local vibe stays warm and welcoming.
Impact on Outdoor Activities
Dry, sunny December weather means you can enjoy outdoor activities with barely any interruptions. Hiking trails around Nagarkot, Shivapuri, and Chandragiri stay open, and you’ll get clear Himalayan views on most days.
If you’re thinking about longer treks, like Annapurna or Everest, December still works at lower elevations—just know that higher passes get colder and sometimes icy. Around Kathmandu, you won’t face extreme weather, but chilly evenings mean a warm layer is a must.
Sightseeing in the city is comfortable, since you don’t have to worry about heavy rain or muddy streets. Calm winds and bright sun make walking tours, cycling, and day trips a lot more fun. For many, winter’s the most reliable time to really explore Kathmandu and its surroundings.
Packing and Accommodation Tips for Christmas in Kathmandu
Daytime in Kathmandu around Christmas feels mild, but mornings and nights can be downright cold. You’ll need the right clothes, ways to stay warm indoors, and smart choices for where you sleep.
Essential Clothing and Gear
December days in Kathmandu top out around 18°C, and nights can drop to about 7°C. So, pack for cool afternoons and chilly evenings.
Layering is your friend. Start with a thermal base, add a long-sleeve shirt or fleece, and finish with a light jacket. A warm hat, gloves, and scarf really help in the mornings and after sunset.
For shoes, pick something sturdy and comfy for walking. Closed shoes with warm socks keep your feet cozy, especially on stone streets. If you’re hiking, lightweight boots beat heavy ones.
Other handy things to bring:
- Compact umbrella or rain jacket (just in case)
- Sunglasses and sunscreen (the sun is strong, even in winter)
- Reusable water bottle (dry air makes you thirsty)
Staying Warm: Heaters and Sleeping Bags
Most Kathmandu hotels and guesthouses don’t have central heating. Rooms can feel colder than it is outside, especially at night.
Many travelers rent or buy a small electric heater, but power cuts do happen. It’s smart to have a backup. A good sleeping bag rated for 0°C to -5°C keeps you warm if the heater fails.
If you’re in a budget place, extra blankets might not cut it. Bringing a sleeping bag liner or a fleece blanket adds warmth without much bulk.
When you book, ask if the room comes with an electric blanket or heater. Some mid-range hotels offer these, but budget spots usually don’t.
Choosing the Right Accommodation
Kathmandu has everything from basic guesthouses to boutique hotels. During Christmas, nights get cold, so heating and insulation matter more than fancy extras.
If you’re on a budget, pick guesthouses with thick bedding and south-facing rooms for more sunlight. Ask about extra blankets before you arrive.
Mid-range hotels often provide small heaters, but check if there’s an extra charge for electricity. Higher-end hotels usually have better insulation and reliable heating, which honestly makes a huge difference at night.
Location is important too. Staying in Thamel or Lazimpat keeps you close to restaurants and shops, so you won’t have to walk far in the cold after dark.
Outdoor Activities and Sightseeing in December
Cool days and clear skies make December a great month for exploring outdoors in Kathmandu. You can trek in the nearby hills, wander historic squares filled with temples and palaces, or take short trips to scenic towns and viewpoints outside the city.
Trekking and Hiking Opportunities
December brings crisp mornings and sunny afternoons, which are perfect for hiking and trekking. In the Kathmandu Valley, you can try moderate trails like Nagarkot, Shivapuri National Park, or Phulchowki Hill. These routes give you Himalayan views without needing to commit to multi-day adventures.
If you want a longer trek, December is still a good time for the Everest View Trek or the Langtang Valley Trek. Skies usually stay clear, so you’ll get awesome views of snow-covered peaks.
Remember, higher altitudes get much colder, with freezing nights. Pack layers, including a warm jacket, gloves, and a hat. At lower elevations around Kathmandu, you’ll need lighter clothes for the day but something warm for after sunset.
Exploring Durbar Square and Cultural Sites
Kathmandu’s Durbar Square sits at the heart of the city as a UNESCO World Heritage Site. It’s honestly one of those places that draws crowds year-round.
If you visit in December, you’ll notice the cooler weather makes wandering the courtyards and temples much more pleasant. You can lose track of time exploring shrines, statues, and the unique Newar architecture, and you won’t have to worry about sweating through your shirt.
You’ll also want to check out Swayambhunath (Monkey Temple), Pashupatinath Temple, and Boudhanath Stupa. They each give you a peek into Nepal’s deep religious traditions and rich history.
The air in winter feels clear and crisp, which honestly does wonders for your photos, especially if you catch that soft morning or late afternoon light.
Since December isn’t peak tourist season, you’ll probably find the monuments quieter and easier to enjoy. Just remember to bring a light sweater or jacket—those shaded corners can get pretty chilly, even in the daytime.
Day Trips and Nearby Attractions
December’s actually a great time for quick trips outside Kathmandu. Many people head to Bhaktapur for its medieval squares and beautifully preserved temples.
Patan is another solid pick. You can explore Patan Durbar Square and maybe spend a little time at its museum.
For those craving mountain views, Nagarkot is hard to beat. It’s about 32 km from Kathmandu, and people flock there for sunrise views over the Himalayas.
If you’re lucky and the sky’s clear, you might even spot Mount Everest in the distance on a December morning.
Looking for something quieter? Panauti and Kirtipur offer a more laid-back vibe, with traditional buildings and some seriously good local food.
The roads usually stay dry in December, so getting around is much easier than during the monsoon.
Comparing Christmas Weather to Other Seasons in Kathmandu
December in Kathmandu brings cool, dry, and steady weather. Daytime temperatures feel mild, but nights can get chilly, and you’ll rarely see rain.
Winter Versus Autumn and Spring
In winter, especially around Christmas, you’ll notice cooler nights with lows near 7°C. Daytime highs usually reach 18–20°C. The air feels crisp, and the sky often stays clear.
That’s why winter stands out as one of the driest, most predictable times in Kathmandu.
Autumn (October–November) feels a bit warmer during the day, with highs around 20–25°C. The evenings stay comfortable, and visibility is usually excellent, which explains why trekkers love this season.
Spring (March–April) brings warmer days, with highs in the mid-20s °C. Flowers pop up all over the valley, and the air doesn’t feel quite as dry as in winter.
But spring afternoons can get a little dusty and hazy, so visibility isn’t always as sharp as it is in December.
Quick comparison:
| Season | Daytime Highs | Night Lows | Rainfall | Conditions |
|---|---|---|---|---|
| Winter (Dec) | 18–20°C | 7°C | Very low | Dry, clear |
| Autumn | 20–25°C | 10°C | Very low | Clear, best visibility |
| Spring | 22–26°C | 12°C | Low–moderate | Warmer, hazier |
How December Differs from Monsoon Months
December in Kathmandu just feels different than the monsoon season. Around Christmas, you’ll probably see only one rainy day in the whole month, and there’s just 23 mm of precipitation.
Humidity stays pretty moderate. There are plenty of sunshine hours, so most days seem perfect for being outside.
The monsoon months (June–September), on the other hand, really bring the rain. July tops the list as the wettest month, dumping over 360 mm of rain on Kathmandu and spreading it out over 20-plus rainy days.
Clouds hang around a lot more, and the air gets sticky and heavy.
Traveling during monsoon? It can get tricky. Flooded roads pop up, trekking trails get muddy fast, and you can pretty much forget about clear mountain views.
In December, you dodge all of that. The winter weather stays steady, so you can actually plan your days without worrying about surprise storms.
Key difference: December brings dry, sunny stability, while the monsoon means frequent storms, high humidity, and not much visibility.
