Weather in Delhi
Delhi has one city tracked on Mausam Online. Live weather, hourly forecasts and air-quality data are available on its page.
Climate & seasons
Delhi has the climate of the north Indian plains: a long, hot summer, a monsoon season and a cool winter. The heat peaks in May and June, when dust storms and the hot, dry wind known as the loo are common. Most of the year's rain falls from June to September, heaviest in July and August. Western disturbances bring occasional winter rain, and dense fog is common on December and January mornings.
When to visit Delhi
The most comfortable months to visit are October to March, after the monsoon and before the summer heat. December and January are the coolest months, with cold nights and morning fog that often delays trains and flights.
Air quality in Delhi
Delhi's page, linked above, tracks PM2.5 and PM10. Delhi follows the broader South Asian pattern — cleaner air in the monsoon, more pollution in winter.
