Bangalore Weather: What Bengaluru’s IMD Forecast Says for 21–24 September 2026

Bangalore weather is not expected to change dramatically in temperature between 21 and 24 September 2026. The more important part of the current forecast is the combination of cloud, rain and gusty winds.

The official India Meteorological Department forecast for Bengaluru, issued at 1:00 pm IST on 20 September 2026, covers Bengaluru Urban and Bengaluru Rural.

What will Bengaluru weather be like from 21 to 24 September?

For Bengaluru Urban, the IMD lists 30°C and 21°C for 21 September, 31°C and 21°C for 22 September, 32°C and 21°C for 23 September, and 32°C and 22°C for 24 September.

Each of these dates is described as generally cloudy with light to moderate rain or thundershowers. The wording is stronger on 21 September: rain may be heavy at times, with gusty winds of 40–50 km/h. From 22 to 24 September, the forecast gives gusty winds of 30–40 km/h.

Is the main issue heat or rain?

The listed temperatures move only slightly across the four-day period. The clearer change is in the weather around those temperatures: cloud, rain or thundershowers are included on every forecast day, while the first day also carries the heavier-rain wording and the higher wind range.

That makes this a forecast to read as a planning constraint rather than a temperature summary. A day that looks moderate on the temperature figures can still be inconvenient for a fixed outdoor plan because the bulletin does not promise a dry period.

What does the forecast not tell us?

The IMD bulletin is arranged by date, not as an hour-by-hour timetable. It therefore helps answer what sort of conditions are expected on each day, but it does not identify an exact time when rain will begin or stop.

For decisions that depend on current conditions, the IMD Bengaluru Meteorological Centre page provides city observations, warnings and a five-day date selector. That is the useful distinction: use the dated forecast to understand the broader pattern, then check the official page rather than treating the daily entry as an exact schedule.

In short, Bengaluru’s 21–24 September outlook is cloudy, with rain or thundershowers each day. Temperatures remain within the listed 21–32°C range, but 21 September deserves extra attention because the forecast includes rain heavy at times and 40–50 km/h gusty winds.
