February warms up. Highs reach 24°C (75°F). Lows sit around 10°C (51°F). Fog lifts. Days stretch longer. This is arguably New Delhi's most walkable month. Rainfall stays low at 20 mm. You can roam from dawn to dusk.

March flips the switch. Highs leap to 29°C (85°F). Lows settle near 15°C (60°F). Heat feels serious. Holi lands this month. The city explodes in color. Rainfall is still light at 18 mm. Midday sun stings, on exposed Red Fort ramparts.

April makes summer official. Highs hit 36°C (97°F). Lows linger around 21°C (70°F). Dry heat renders 11 a.m. to 4 p.m. outdoors brutal. Rainfall drops to 15 mm. Tourist numbers shrink. Locals shift life to dawn and dusk.

May is peak heat. Days regularly top 39°C (103°F). Nights offer little relief at 25°C (78°F). Air feels oven-baked. Dust storms, called loo, can whip through afternoons and tint the sky yellow-brown. Late-month pre-monsoon showers may drop 30 mm. Yet the water vanishes on contact. The city is at its quietest.

June teeters on the edge. Daytime highs still reach 39°C (102°F). Humidity climbs as the monsoon creeps north. Late June usually delivers the first real downpour. Relief is instant. Rainfall jumps to about 74 mm. The mix of searing heat and rising humidity before the break feels heavier than May's dry blast.

July is full monsoon. Highs drop to 35°C (96°F). Sounds like a relief. Add humidity plus 211 mm of rainfall. Downpours hit in fierce bursts. Streets in Old Delhi flood fast. Between storms the city turns green. Mughal gardens look their most lush. Expect disruptions to travel plans.

August is the wettest month. Roughly 234 mm of rain. Lows hold at 26°C (80°F). Monsoon is fully established now. It rarely rains all day. Showers can still be torrential. Humidity is at its peak. Yet New Delhi feels atmospheric. Purana Qila moat fills. Peacocks display in Lodhi Colony. India Gate stonework gleams.

September sees monsoon begin retreat. It does not leave quietly. Rainfall drops to about 124 mm. Daytime temperatures stay near 34°C (93°F). Humidity lingers in the air. Late September can deliver monster downpours. These mark the system's last push. Crowds are still thin. The city feels slightly exhausted.

October is the reset. Monsoon withdraws, skies clear. New Delhi enters festive season. Dussehra and Diwali land here. Highs still reach 33°C (91°F). Humidity drops dramatically. Heat becomes far more tolerable. Rainfall plunges to 15 mm. Caveat: late October air quality worsens. Sometimes the drop is sharp.

November brings pleasant weather. Highs hit 28°C (83°F). Lows settle around 13°C (55°F). Prime sightseeing territory. Rainfall is almost nonexistent at 5 mm. The downside is significant. Early to mid-November air quality can be worst of the year. Particulate levels hit hazardous. Check conditions before planning.

December feels like winter here. Highs reach about 22°C (73°F). Lows drop to 8°C (47°F). Chilly evenings surprise rooftop diners. Connaught Place feels bracing. Rainfall stays minimal at 8 mm.
