New Delhi Weather in September

September: sticky, unsettled days

September still feels hot and humid in New Delhi. Highs reach 33°C, and nights stay warm at around 24°C. Rain falls on 13 days, so showers can interrupt a day out, though there's still plenty of sunshine between them.

You can visit indoor sights like the National Museum or browse the covered lanes of Dilli Haat. Humayun's Tomb and Lodhi Garden are lovely when the skies clear, but muddy paths and sudden downpours can make long outdoor visits less enjoyable. It's wetter than October, when rain drops sharply, so keep some flexibility in your plans.

Festivals and quieter streets

Ganesh Chaturthi is celebrated in Delhi in September some years, with worship at temples and local gatherings. Its date follows the Hindu calendar, so it doesn't fall in September every year. Check the calendar for your travel year before making it part of your plans.

If you hate crowds, September is calmer than the busy November-to-February season. It's a shoulder month, after the peak monsoon and before Delhi's most popular cooler-weather stretch. Hotels and flights can be better value than in winter, though prices vary and rain can affect sightseeing.

Make the weather work

Travelling with kids? Plan a flexible day, with an indoor stop ready if rain rolls in. The heat and humidity can make afternoons tiring, so save a long walk around Qutub Minar for a clearer, cooler part of the day.

For a practical rain-day route, take the Delhi Metro to Central Secretariat, then visit the National Museum nearby. It's a useful alternative to getting stuck in road traffic during a downpour. If the weather clears, you can carry on to India Gate, but expect wet pavements after rain.
