      Averages of daily model data (ERA5 reanalysis) for Kaza, 2001–2025. The model smooths the valley: on a still winter day in the sun, it often feels nearer 0 °C than the average high suggests, and the wind makes it feel far colder.

      What it feels like

      June to September

      Warm in the sun, cool in the shade, cold after dark. Sunburn comes fast at this height. Pack layers, a hat and sunscreen.

      October

      The clearest skies of the year, and the first hard frosts. Nights fall well below freezing; the passes can close any week.

      November to March

      Deep cold. Nights in Kaza are usually −15 °C to −30 °C, water pipes freeze, and snow can shut roads for days. Come only through Kinnaur.

      April and May

      The thaw. Days warm up but nights still freeze, and melting snow makes roads muddy and side valleys slow.

      Quick answers

      What is the weather in Spiti in October?

      Clear, dry and cold at night. In Kaza, October averages a high of about 7 °C and a low of about −7 °C, and the first heavy snow usually closes Kunzum Pass from mid-month.

      How cold is Spiti in December?

      Very. Kaza averages a low of about −18 °C in December, and the coldest nights fall below −30 °C. Days in the sun feel warmer than the average suggests, but the wind is bitter.

      When does it snow in Spiti?

      Mostly from December to March, with the heaviest snow in January and February. The first snow on the passes can come in October.

      Does it rain in Spiti?

      Very little. Spiti lies in the rain shadow of the Himalaya, so the monsoon that soaks Manali and Shimla barely reaches it. The rain that hits the Kinnaur road in July and August is what causes landslides on the way in.
