India's climate varies more dramatically by region than almost any other country of comparable size. The same calendar month can mean cold fog in Delhi, pleasant warmth in Goa, extreme heat in Rajasthan, or heavy rain on the Kerala coast. National season labels — winter, summer, monsoon, post-monsoon — describe broad meteorological patterns but do not predict conditions at a specific destination.
Understanding weather in India requires two: the national seasonal structure, and how that season actually behaves in the region you are visiting.
Seasonal Structure
India follows four broad meteorological seasons that repeat annually. Their effects differ significantly by region — see the Regional Variation tab for how each season plays out in specific parts of the country.
Winter (December – February)
Winter is the most comfortable season for travel across most of India. Temperatures are moderate across the plains and pleasant in coastal and southern regions. In Himalayan regions, snowfall is heavy and high-altitude roads and passes are closed.
Regional Variation
• North plains (Delhi, Agra, Jaipur) is 5°C – 20°C. Cold nights, mild days.
• Rajasthan desert is 4°C – 22°C. Can drop close to 0°C at night in December–January.
• Himalayan regions is -20°C to 5°C depending on altitude. Heavy snow.
• Central India (Madhya Pradesh, Maharashtra) is 10°C – 25°C. Pleasant.
• South India (Tamil Nadu, Kerala, Karnataka) is 18°C – 30°C. Warm and dry.
• Northeast India is 5°C – 18°C. Cool and dry.
Summer (March – May)
Temperatures rise sharply across the plains from late March onward. By May, the North Indian plains, Rajasthan, and Deccan Plateau (Maharashtra, Karnataka, Andhra Pradesh, Tamil Nadu, and Kerala) are at their hottest.
Regional Variation
• North plains (Delhi, Agra, Lucknow) is 25°C – 45°C. Intense heat from April–May.
• Rajasthan is 28°C – 48°C. Among the hottest areas in the country in May.
• Himalayan regions (Ladakh, Manali, Shimla) is 5°C – 25°C depending on altitude. Cool and clear.
• Central India is 25°C – 42°C.
• South India is 25°C – 38°C. Hot and humid on the coast.
• Northeast India is 15°C – 30°C. Pre-monsoon showers begin in April.
Monsoon (June – September)
The Southwest Monsoon arrives at the Kerala coast in early June and progressively moves northward, reaching Delhi and Rajasthan by July. The monsoon does not arrive everywhere simultaneously — onset dates and withdrawal dates vary by region and year.
Regional Variation
• North plains (Delhi, Agra, Lucknow) is 25°C – 40°C. Hot and humid.
• Rajasthan is 28°C – 42°C. Hot due to limited rainfall.
• Himalayan regions is 10°C – 25°C depending on altitude. Rain in Himachal and Uttarakhand.
• Central India is 22°C – 35°C. Heavy and sustained rainfall.
• South India is 23°C – 33°C. West coast receives peak annual rainfall June–September.
• Northeast India is 18°C – 30°C. Extremely heavy rainfall across the region.
Monsoon does not make travel impossible, but it changes the travel significantly. South India and the Deccan are greener and cooler during monsoon.
Post-Monsoon (October – November)
Rainfall reduces and temperatures moderate across most of the country from October onward. This is the transition into the second-most-comfortable travel window of the year. The Himalayan high-altitude roads begin seasonal closures again as snowfall returns to passes in October–November.
Regional Variation
• North plains (Delhi, Agra, Lucknow) is 15°C – 33°C. Temperatures dropping through November.
• Rajasthan is 14°C – 33°C. Rapidly becoming comfortable again by October.
• Himalayan regions is -5°C – 15°C. Snow returning to high passes from October.
• Central India is 15°C – 30°C. Pleasant and dry.
• South India is 22°C – 32°C. East coast entering Northeast Monsoon rainfall.
• Northeast India is 10°C – 25°C. Stabilizing after monsoon withdrawal.
Travel Implication
Weather directly affects transport, accommodation availability, park access, and road conditions. Here is what to plan for by season.
Winter (Dec–Feb)
North India fog causes flight delays in early morning, sometimes severe. Build buffer time into any itinerary involving early morning departures or onward connections in December and January. High-altitude Himalayan roads are closed but Leh is accessible by air year-round.
Summer (Mar–May)
North Indian plains and Rajasthan see extreme heat. Heat-related illness is a genuine risk at 45°C+ temperatures without precaution. Himalayan destinations become accessible as snow clears from passes.
Monsoon (Jun–Sep)
Monsoon affect all Himalayan road corridors. Roads can be blocked for hours or days. Build significant flexibility into Himalayan itineraries during this period. Coastal flooding and cyclone risk on the Bay of Bengal coast increases from October.
Post-Monsoon (Oct–Nov)
High-altitude passes begin closing from October as snowfall returns. Plan Himalayan road travel to conclude before the second week of October.
