India weather on the northern plains is at its most temperate, dry and sunny from October to March. Delhi and nearby States can experience light to heavy fog during mid-December to mid January, when there can also be a heavy frost. India weather south into Rajasthan can be relatively unaffected.

North of Delhi, freezing temperatures are sometimes encountered at night in January. When the sun burns off the mist, temperatures rise again. May and June are extremely hot. India weather in the Himalayan Foothills and beyond is at its best from March to October. During Monsoon there is some relief from the heat of the plains. There can be snowfalls in some of the hill stations late December to February. Further north, Kashmir and Ladakh have their best season in July and August, since the region is in the rain-shadow of the first row of Himalayan Mountains.
