Weather in Bengaluru in January

Prime time. If you get to pick your dates, January is the one. Highs average 29.2 °C, lows 14 °C, and rain falls on 1 days — nothing in the month is working against you.

January ranks 2 of 12 in Bengaluru. Only December scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain falls on only 1 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 29.2 °C days and 14 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 11 days top 30 °C — hot spells arrive, but they break; the day swings 15.2 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest January day reached 33.3 °C and the coldest night fell to 8.3 °C.

January is dependably dry, and that reliability is the point: across the twenty years measured, the wettest January on record still only managed 11 mm, and the driest managed 0 mm. There is no meaningful variability to plan around, which makes this one of the few months anywhere that you can build a fixed outdoor itinerary against without a fallback. The wettest single day in twenty years of Januarys brought 8 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.

Wind is light at 8.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 63%.

How January sits in the year

The month is on the way up: 2.2 °C warmer than December, and February adds another 2.9 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in January

Bengaluru sits close enough to the equator that daylight barely moves all year — 11.4 hours in January, 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. Within January itself the daily swing is 15.2 °C, so mornings and afternoons need different clothes.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

January in Bengaluru versus nearby

If Bengaluru is one option among several, the nearby comparison is worth making. Mysuru is the weaker option in January — 2 °C warmer, the same number of rain days. Kallakurichi is the weaker option in January — 2.3 °C warmer, 1 day more rain.

So: January is effectively as good as it gets here — 6 points behind December, which is inside the margin where the weather stops being the deciding factor and price starts being it.
