Key Takeaways
- Snow in Tawang town falls reliably in December and January, often into February.
- Sela Pass (4,170m) is snow-covered to some degree almost year-round, so you can usually see snow there October to April.
- October and November are clear and good for sightseeing. Snow that early is a gamble.
- January is the coldest month and the safest bet for heavy snow. Budget 5 to 6 days from Guwahati.
Most people asking about Tawang want to know one thing: when will there be snow? The short answer is that snow in Tawang town falls reliably during December and January, and often stretches into February (Tawang, Wikipedia). Sela Pass, higher up on the way in at 4,170m, stays snow-covered to some degree almost all year (Sela Pass, Wikipedia). October and November are crisp and clear and better for mountain views than for snow. Here's the full month-by-month picture.
Month by Month: Snow and Conditions
| Month | Snow in Tawang town | Sela Pass | Rough feel | Roads | Good for |
|---|---|---|---|---|---|
| October | Unlikely | Mostly clear, some snow possible | Cool days, nights near freezing | Generally open | First visit, clear mountain views |
| November | Possible, not reliable | Snow increasingly likely | Cold, nights below freezing | Usually open | Late-autumn trip, fewer people |
| December | Reliable | Snow-covered | Very cold, nights well below freezing | Open, weather-dependent | Your first proper snow |
| January | Reliable, heaviest | Deep snow, coldest | Coldest month, lows around −8°C possible | Open, short closures after heavy snow | Peak snow and winter landscapes |
| February | Often still snowy | Deep snow | Very cold, easing late in the month | Similar to January | Snow with slightly longer daylight |
| March | Thaw begins, light snow still possible | Still snow-covered | Cold easing | More stable | Snow without peak-winter harshness |
| April | Unlikely in town | Snow lingers up high | Mild days, cold nights | Stable | Green valley with snow still on the passes |
Conditions shift year to year. Treat this as the typical pattern, not a guarantee, and check road and pass status close to your travel date.
December to February: The Reliable Snow Window
If snow is the whole point of the trip, come in this window, and January is the safest single month. Tawang gets snowfall every winter in this stretch, and higher areas hold it deeper and longer. It is also hard weather: January's daily low sits around −2°C and can drop to −8°C or lower (Tawang, Wikipedia). A clear morning can turn into a whiteout by afternoon. Keep your itinerary loose and expect at least one plan to change.
October and November: Clear Skies, Snow Is a Gamble
October is the easiest time to visit, especially on a first trip. The monsoon is done, the mountain views open right up, and the cold is real but manageable. You can do Tawang Monastery, Nuranang Falls, and Sela Pass without snow being the deciding factor. November turns noticeably colder and the first snow of the season sometimes arrives late in the month, but you cannot plan around it. If you specifically want to stand in snow, don't book October and hope.
March and April: The Thaw
By March the hardest cold eases. Town-level snow becomes unlikely, but Sela Pass and the higher country stay white well into April. This is a good window if you want the passes still under snow without January's harshness, and the valley itself starting to green up.
Sela Pass and Bum La Pass in Winter
Sela Pass (4,170m) carries the main road to Tawang and is usually kept open year-round by the Border Roads Organization, with occasional short closures after heavy snow or a landslide (Sela Pass, Wikipedia). Sela Lake beside it often freezes solid in winter. You will almost certainly see snow here on any winter crossing.
Bum La Pass (4,600m), on the international border, is more sensitive to winter weather and can close without much notice (Bum La Pass, Wikipedia). Access also depends on permits and military clearance regardless of season. Treat it as a highlight if conditions allow, not a fixed part of the plan.
What to Pack
For a winter trip: thermal base layers, a heavy insulated jacket, a warm hat and gloves, and waterproof footwear with grip for snow and ice. Days can be bright and deceptively warm in the sun, so sunglasses and sunscreen matter too. October and November are milder but still need a proper warm layer for the evenings and for Sela Pass.
Planning Your Trip
Budget at least 5 to 6 days from Guwahati, routing through Bomdila and Dirang, so you are not rushing the mountain roads or the altitude. Our Tawang Experience, 5 Days covers the core route, and the Himalayan Trails: Tawang and Sangti piece has a longer version if you want to add the quieter valleys.

Frequently Asked Questions
What is the best time to visit Tawang?
October to April is the main travel window. October and November are best for sightseeing and clear mountain views. December to February gives you the strongest chance of snow, with January the most reliable. March and April work well if you want the passes still under snow without peak-winter cold.
Which month has the most snowfall in Tawang?
January. Tawang gets snow every year through December and January, and January is also the coldest month, so it is the safest bet for deep snow in the town itself.
When does snowfall start in Tawang?
Usually December. Light snow occasionally arrives in the last week or two of November, but it is not something you can plan a trip around.
Will there be snow in Tawang in October?
Very unlikely in the town. Sela Pass may have some old snow, but if standing in fresh snow is the goal, October is the wrong month. Come for the clear views instead.
Is there snow at Sela Pass in November?
Often, yes, and it becomes more likely as the month goes on. Sela Pass sits at 4,170m and is snow-covered to some degree for most of the year, so a November crossing usually has snow around even when the town doesn't.
Does it snow in Tawang in December?
Yes, reliably. December is the start of the proper winter season, temperatures are very cold, and snowfall is expected. Keep your itinerary flexible, because weather can change fast and affect road access.
Can you see snow in Tawang in March or April?
Town-level snow is unlikely by then, but Sela Pass and the higher areas hold snow well into April. It is a good window for snow on the passes with a milder valley.
Is Tawang accessible in winter?
Yes, but snow and weather can affect individual routes and high-altitude stops. Sela Pass and Bum La Pass are the most sensitive. Check current road and access conditions close to your travel date rather than assuming every stop will be open.
How many days do you need for a Tawang trip?
At least 5 to 6 days from Guwahati, to cover the route through Bomdila and Dirang without rushing.
