Visiting Bengaluru in September

September: damp days

September is one of the wetter stretches in Bengaluru, and it's not the month to pick if you have a choice. December and January are much kinder. In September you'll get warm, cloudy, sticky days, with highs around 28°C and evenings cooling to about 19°C. Rain falls on 18 days, so a shower can cut into your plans, and with little sunshine you'll want to be flexible about when you head out.

Cubbon Park and Lalbagh are still nice for a stroll between showers, though muddy paths can spoil a long walk. That's where the indoor options come in. Save some time for the Visvesvaraya Industrial and Technological Museum or the National Gallery of Modern Art, and don't count on a dry day for a full sightseeing schedule.

Festivals and crowds

Ganesh Chaturthi often falls in September, though the date shifts from year to year. If it lines up with your trip, you may see decorated Ganesh idols and local celebrations around the city. Check the festival date for your year before you build a visit around it.

If you hate crowds, September is generally quieter than the December and January season, when the city fills up. The trade-off is the weather. You may find better-value stays than in peak months, though prices vary, and you'll be dealing with more rain than you would in those busier months.

Make rainy days easier

Rain can slow traffic, especially on busy roads, so leave extra time when you're crossing the city. The Namma Metro is a good way to reach central sights without relying on a car through wet, congested streets.

Travelling with kids? Keep the museum as a backup for a rainy afternoon. The Cubbon Park Metro station is close to the park, so it's easy to swap a soggy walk for an indoor visit. When the weather turns wet, stop at MTR near Lalbagh for a masala dosa.
