Weather in Bengaluru in December

Prime time. If you get to pick your dates, December is the one. Highs average 27 °C, lows 14.4 °C, and rain falls on 3 days — nothing in the month is working against you.

December is the highest-scoring month of the twelve. The nearest rival is January, and the month at the other end of the year is May.

Rain falls on only 3 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest December day reached 32.5 °C and the coldest night fell to 8.4 °C, and the wettest single day dropped 37 mm — roughly 247% of the month's rain in one day.

This is the volatile part. December rainfall has ranged from 1 mm to 61 mm across the twenty years measured — a 60 mm spread around an average of 15 mm. The average is real but almost no individual December looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 8.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 74%.

How December sits in the year

Temperatures hold steady either side: 26.6 °C in November, 27 here, 29.2 in January. Nothing about the timing within the month matters much. Rain has already shifted: 6 days fewer than November had.

Daylight in December

Bengaluru sits close enough to the equator that daylight barely moves all year — 11.4 hours in December, 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

Peak season. Expect the highest prices of the year and to be booking well ahead.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

December 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, the same number of rain days. Kallakurichi is the weaker option in December — 2.5 °C warmer, 5 days more rain.

So: December is the answer for Bengaluru. If it is booked out or priced out, January is the next best thing at 6 points behind, and May is the month to keep off the shortlist.
