The best time for Yala Peak climbing is October to mid-November, followed by April to early May. Autumn gives the clearest summit views and the driest trail. Spring is warmer, with the rhododendrons out lower in the valley, but cloud builds earlier in the day. Winter is possible but very cold, and the monsoon months are the wrong time to go.
This guide explains what each season means for the walk in and for summit day at 5,520m. Use it to match the climb to your travel dates.

Why the season matters more on a climb
On a trek, a cloudy day is a disappointment. On Yala Peak it can mean turning back. Summit day starts around 4am, and you want a clear, calm morning for the snow slopes near the top. There are no flights on this trip, so weather delays come from the road and the mountain, not the airport.
Autumn: September to November
Autumn is the main Yala Peak climbing season. The monsoon clears out and the air is dry. On a good morning you can see Langtang Lirung (7,234m) and Shishapangma in Tibet from the summit. It is also the busiest time in the Langtang Valley.
September
The monsoon usually withdraws from Nepal in late September or early October, so early September can still be wet below Lama Hotel. Late September is much more reliable and quieter than October. If your dates are fixed in early September, plan for some rain on the walk in.
October
October is the best single month for most climbers. Mornings are usually clear, the trail is dry and the days are mild for walking. Teahouses at Kyanjin Gompa are at their busiest. Late storms can still hit in October, so a spare day in your plans is worth having.
November
November keeps the clear skies with fewer people on the trail. Nights get noticeably colder, especially at Base Camp (4,800m), and the snow near the summit gets harder through the month. Bring a warm down jacket and a sleeping bag rated well below freezing. Early and mid-November are better than the last week.
Spring: March to May
Spring is the second-best season. The valley warms up, the rhododendrons flower in the forest below Lama Hotel, and summit conditions are generally good. The trade-off is cloud. It tends to build from late morning, so views from the top are less certain than in autumn.
March
Early March can still feel like winter higher up, with cold nights and hard snow near the summit. Late March is milder and a good choice for climbers who want a quieter trail.
April
April is the best spring month. Days are warm on the walk in, the forest is in flower and the summit is usually reachable on a clear early morning. The upper slopes often hold more snow than in autumn. It softens as the sun comes up, which is one reason for the early start.
May
Early May is still a good time to climb. From mid-May the pre-monsoon haze and afternoon cloud increase, and the first monsoon rain can arrive near the end of the month. If May is your only option, aim to be on the summit in the first half of the month.
Winter: December to February
Winter brings clear skies and an empty valley, but it is cold. Nights at Kyanjin Gompa and Base Camp are well below freezing, and the snow near the summit is often hard and icy. That makes crampon work more demanding for first-time climbers.
We only suggest winter to climbers with some cold-weather or crampon experience. If you are thinking about it, message us first so we can talk through the conditions, your gear and your experience.
Monsoon: June to mid-September
The monsoon is the wrong time for Yala Peak. Rain is frequent, the forest trail is slippery with leeches, and cloud often hides the mountains for days. The road to Syabrubesi is also more likely to be blocked by landslides. Summit attempts are possible in a break in the weather, but the chance of a clear morning is low.

Planning Tips for Each Season
- Autumn: book early for October, and allow one spare day in case a storm delays the summit.
- Spring: plan the summit for the first half of the trip if you climb in May, and expect afternoon cloud.
- Winter: bring a warmer sleeping bag and gloves than you would for autumn. Check our Yala Peak packing list.
- Any season: the Kyanjin Ri day before Base Camp is the same in every month. Our Yala Peak itinerary explains why it matters.
