Jammu Duggar · Western Himalaya & Trans-Himalaya

Terrain and eco-zones

Subtropical at the foot and temperate on the ridges — a range of nearly 2,000 m inside sixty kilometres. Jammu city touches 44 °C in June and drops to 5 °C in January; Patnitop, 100 km away and 2,000 m up, holds snow. Rainfall is around 1,100 mm at the Shivalik crest and falls off sharply on the kandi apron, where the same storm runs off the gravel instead of soaking in.

Landforms

Shivalik outer ranges — soft Tertiary sandstone and conglomerate, easily gulliedDuns — flat-floored valleys caught between two Shivalik ridges, the best farmland in the regionThe kandi piedmont, a boulder-and-gravel fan with a deep water tableKhadds and nallahs — seasonal torrents that cut vertical banks and shift course after every monsoonThe Trikuta massif above Katra, three peaks and the cave shrine inside themThe Chenab gorge at Reasi, where the river cuts through the Shivaliks in a slot several hundred metres deep

Through the year

SeasonMonthsTypicalWhat it is like
WinterDecember–February5–22 °CClear and dry at Jammu, snowbound above 1,800 m. Lohri in mid-January is the region's largest household festival, and the sund and panjeeri made from dry ginger, edible gum and nuts are winter foods by design.
SpringMarch–April15–32 °CMustard and wheat harvest, Baisakhi fairs, and the Gujjar and Bakerwal flocks beginning their climb from the kandi winter grazing towards the Pir Panjal passes.
SummerMay–June28–44 °CThe plain becomes unlivable by afternoon and the hill stations fill. Mango, jamun and the wild pomegranate that becomes anardana all ripen in this window.
MonsoonJuly–mid-September25–36 °CSharp, short, heavy. The khadds run for the only time in the year, the Shivalik slopes shed soil visibly, and roads on the Chenab approach close for landslides most seasons.
Post-monsoonOctober–November15–30 °CThe clearest air of the year and the peak of the Vaishno Devi walking season. Navratri, Diwali and the Jhiri fair fall in it.

Best time to visitOctober to March for the plain, the shrines and the food. April to June for Patnitop, Sanasar and Bhaderwah on the Chenab approach. The Vaishno Devi trek is walkable year-round but the Navratri weeks in March–April and September–October see the heaviest crowds of the year.
