Season by season and month by month: what the weather, the views and the trails are like on the Singalila Ridge.
Last updated
For the clearest views of Everest, Kanchenjunga, Lhotse and Makalu from Sandakphu, go between October and early December. For rhododendrons in bloom and milder days, go between March and May. Both seasons are good for every trek we run.
Winter (late December to February) is cold but often crystal clear, with a chance of snow on the ridge. The monsoon (June to September) brings heavy rain and hidden peaks, and Singalila National Park usually closes to trekkers during its peak.
| Season | Months | Weather on the ridge | Mountain views | Good for |
|---|---|---|---|---|
| Spring | March to May | Mild days, cold nights, afternoon haze and the odd shower | Good in the early morning | Rhododendrons, birds, first-time trekkers |
| Monsoon | June to September | Heavy rain, fog, slippery and leech-prone trails | Rarely visible | Park usually closed at the peak; short hikes only |
| Autumn | October to November | Dry, stable, crisp mornings, cold nights | Best of the year | Photography, summit sunrises |
| Early winter | December | Clear and cold, nights well below freezing | Excellent | Quiet trails, sharp views |
| Winter | January to February | Very cold, snow possible above 3,000 m | Often excellent between storms | Snow lovers with warm gear |
| Trek | Best months | Notes |
|---|---|---|
| Sandakphu Phalut Trek | March to May, September to December | The longest trek and highest nights; autumn gives two clear summit mornings |
| Sandakphu Short Trek | October to December, March to May | Four days, so a good fit for a clear-weather window |
| Singalila Red Panda Excursion | March to May, September to November | Quieter forests; sightings are never guaranteed |
| Tonglu Overnight Hike | Most of the year | Low and short enough to run in most seasons, weather permitting |
Darjeeling town is mild for most of the year, but the ridge is much colder. Sandakphu sits at 3,636 m, more than 1,500 m above Darjeeling, and temperatures drop quickly after sunset. Expect nights near or below freezing from October to April, and well below freezing from December to February. Even in May, early mornings on the summit can be close to 0 °C.
Wind makes it feel colder still, especially at Phalut and on the open grassland near the summit. Pack for the coldest night of your trek, not the warmest day.
The Himalayan panorama is clearest in the first hours after sunrise. Clouds usually rise from the valleys by late morning, especially in spring. That is why the itineraries have you at Sandakphu and Phalut overnight: you wake up on the ridge in time for the sunrise over Kanchenjunga.
No season guarantees a clear view. Even in November, a weather system can hide the peaks for a day or two. Treks with more nights high on the ridge, like the full Sandakphu Phalut traverse, give you more chances.
Snow is most likely from late December to early March, and occasional falls happen in November and April. Fresh snow makes the ridge beautiful, but it also makes the trail slower and the ridge road harder for vehicles. Plans can change at short notice for safety, and your guide will decide on the day.
If you want a snow trek, bring insulated boots, microspikes if you own them, and a proper down jacket. Our Sandakphu trek packing list has a winter section.
October, especially around the Durga Puja and Diwali holidays, is the busiest time on the ridge. Lodges fill up and groups are larger, so book a few weeks ahead. Late November, December and March are quieter. Plan your arrival with the getting here guide and check ID needs in the permit guide.
