Weather in Bengaluru in August
India · 20-year averages, August
A good month. August works. It is not the peak, but nothing about it fights you. You should expect rain on 17 days of the month, which is more days wet than dry.
August ranks 7 of 12 in Bengaluru: past the worst of the year but short of December, which is the month to book if the dates are open.
Rain on 17 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.
What the averages hide
Averages flatten a month, and this one hides a few things: 5 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest August day reached 33.1 °C and the coldest night fell to 16.5 °C, and the wettest single day dropped 52 mm — roughly 46% of the month's rain in one day.
August is moderately variable: 41 mm in the driest year against 263 mm in the wettest, around an average of 112 mm. Roughly two Augusts in three land near that average, and the third does something else entirely.
Wind is light at 14.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 79%, high enough to notice on the warm days without dominating them.
How August sits in the year
Temperatures hold steady either side: 28.3 °C in July, 28 here, 27.8 in September. Nothing about the timing within the month matters much.
Daylight in August
Bengaluru sits close enough to the equator that daylight barely moves all year — 12.6 hours in August, against a range of just 1.5 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.
An inland climate
Despite being inland, the year stays fairly even: 21.1 °C between the year's warmest afternoons and coldest nights. At 920 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly.
How busy it gets
Shoulder. The value months — prices ease off and you get the place closer to itself.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
August in Bengaluru versus nearby
If Bengaluru is one option among several, the nearby comparison is worth making. Mysuru is close enough to be a coin toss — within a degree on temperature, 5 days more rain. Kallakurichi is the weaker option in August — 6.8 °C warmer, 2 days less rain.
So: August is a compromise. December is 31 points better and is what Bengaluru is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
