Thời tiết Shimla (Himachal) vào tháng 5

May is inside the Parvati valley's good stretch - the trekking season runs roughly March to September, with December to February ruled out by snow - and forum reports of late April into early May describe open sun, around 20 to 22C by day and a chill in the wind, with nights down near 6 to 12C. The river is full and the pine and deodar are at their greenest. This is the month people use as a base for the walks: Kheerganga above all, plus Tosh, Pulga, Kalga and Malana, with Manikaran's gurdwara and hot springs down in the valley. The record: 23.1C days against 8.5C nights, 9.4 precipitation days carrying 48.2mm, 12 hours of sun and AQI 83.

Forum posters describe December in Shimla as chilly, typically ranging between 8C and -2C, with genuinely low odds of snow in the first three weeks of the month despite the wintry temperatures - posters note Shimla hasn't seen a proper white Christmas in over a decade, with snow around New Year's happening roughly one year in three. Posters consistently recommend mid-December through mid-January as the better window for snowfall specifically, since accumulation tends to build later in the season rather than early December. Posters describe December 20 through January 10 as Shimla's peak season regardless of actual snow, driven by holiday travel, and consistently recommend booking accommodation well in advance for that stretch. Posters generally rate December as a cold but reliably accessible time to visit Shimla, with road conditions between Delhi, Shimla, Manali and Chandigarh staying open even when snow does fall.

June is peak season in Shimla, and the forum's warning is about the last week of it: the monsoon typically arrives around 23 June, with the first heavy showers by the 29th. Before that it is the pleasant hill-station weather people come for — near 23°C by day, 12 at night. After it, rain that sometimes does not stop for 24 hours or more. The record already puts June at sixteen wet days, so "occasional showers of small duration" is the optimistic reading of the month. Late June is also, in a regular's word, haywire — the busiest week of the tourist year, good places packed and on-the-spot prices sky high. Book ahead.
