Peak Season to visit Spiti is from mid-May to mid-July, when the weather is bearable and warm and all passes, link roads and hotels are open for visitors.
Shoulder Season: September to late October, which is the autumn season when the roads are strewn with leaves and the Spiti River is a beautiful turquoise colour. It can get quite cold night, almost two to three degrees, so keep that in mind while planning your trip.
Off-season: April to mid-May is when the snow starts melting and a few link roads, including the one from Kaza to Losar, open. The few homestays and hotels start operations in June, and this is also the time when major passes, such as the Kunzum Pass, open. So if seeing snow-covered peaks is on your bucket list, then this is a good time to go.
