Weather in Bengaluru in October
India · 20-year averages, October
A good month. October is a solid month to be in Bengaluru. You should expect rain on 18 days of the month, which is more days wet than dry.
October ranks 8 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 18 days, 4 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: 4 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest October day reached 33.3 °C and the coldest night fell to 11.8 °C, and the wettest single day dropped 55 mm — roughly 39% of the month's rain in one day.
October is moderately variable: 26 mm in the driest year against 431 mm in the wettest, around an average of 141 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.
Wind is light at 7.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 81%, high enough to notice on the warm days without dominating them.
How October sits in the year
Temperatures hold steady either side: 27.8 °C in September, 27.1 here, 26.6 in November. Nothing about the timing within the month matters much. Rain is the thing that moves: November brings 9 days less of it, so pushing the dates later buys drier weather.
Daylight in October
Bengaluru sits close enough to the equator that daylight barely moves all year — 11.9 hours in October, 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
Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
October 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, 1 day more rain. Kallakurichi is the weaker option in October — 4.6 °C warmer, 2 days more rain.
So: October 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.
