South Asia in March: Weather, Crowds & What to Expect

Northwestern Drylands (Pakistan, Punjab & Rajasthan, Gujarat)

By March the heat becomes noticeable in the plains and deserts: Delhi and Lahore can feel hot by mid-afternoon, while Jodhpur and Bikaner heat up earlier. Dust storms and dry gusts appear; blossom season is limited to irrigated areas and orchards. For travelers, days are good for early starts and evening museum visits; hydration and a hat are essential and pre-booking accommodations for popular desert tours helps. Road dust and pollen can aggravate allergies.

The Indo‑Gangetic Plain & Bengal Coast (Delhi, Uttar Pradesh, Bihar, West Bengal, Bangladesh)

By March the plains heat becomes obvious and pre-monsoon dust increases in many cities: Holi celebrations add colour in towns like Mathura and Kolkata but also raise airborne particles. Delhi and Lucknow see warm afternoons; Bengal coast begins to feel muggy as humidity creeps up. For travelers, early starts and siestas work well-carry sun protection and expect crowded festival periods around Holi. Agricultural burning sometimes reduces air quality across northern plains.

Nepal & Bhutan (Himalayan lowlands to high passes)

March sees spring awakening: rhododendrons and apricot blossoms start colouring lower slopes and trekking routes to Annapurna and lower Everest become popular for clear, cool days. Elevation matters-Kathmandu is pleasantly mild, whereas passes retain snow. This month is one of the first reliable seasons for trekking-lodges reopen and transport schedules firm up-so expect a gradual crowd increase and rising prices. Pack warm nights gear but lighter daytime layers; insect activity is still low.

Northeast India & the Eastern Himalaya (Assam, Meghalaya, Sikkim, Arunachal, Nagaland, Manipur, Mizoram)

In March the region enters a lively pre-monsoon bloom: orchids and wildflowers show in the hills, while plains grow warmer and more humid by late month. Darjeeling and Shillong have long daylight and excellent trekking weather at moderate altitudes; outdoor activities are very comfortable. Be mindful that heavy pre-monsoon thunderstorms begin to occur in some years, especially toward May, and road conditions can shift rapidly. Early bookings are sensible for guided treks and wildlife tours.

Peninsular India & the Western Ghats plus Sri Lanka (Kerala, Tamil Nadu, Karnataka, Goa, Andhra, Telangana, Sri Lanka)

By March heat builds noticeably in the southern plains and on the east coast: Chennai becomes sticky, while afternoon sea breezes on the southwest coast temper high daytime readings. Wildflower season is winding down in hill areas but lowland wetland birdwatching is still rewarding. Travelers should plan beach and coastal activities in the mornings and evenings; inland exploration can be hot, so carry sun protection and plenty of water. Sri Lanka’s cultural triangle is hot but manageable for early-morning temple visits.

Maldives & Lakshadweep (Indian Ocean atolls)

March continues warm and often dry, though humidity slowly increases toward month-end: water temperatures peak for comfortable swims and underwater photography is excellent. Surf spots can be productive depending on reef exposure; island hopping is straightforward with reliable boat services. This month is very popular for honeymoon travel and diving, so expect crowded popular reefs and full resorts. Pack lightweight tropical clothes and sun protection for long days outdoors.
