Resenärernas anteckningar om Bengaluru i september
Regulars describe rain and cooler temperatures as directly linked here - one visitor's real-time report simply noted it was already raining and the weather had turned cooler as a result, capturing how quickly a shower shifts the day's feel. Our row backs the wet, mild-for-the-tropics read, 28.6C reading as a hot 30C at 81 percent humidity, over 20.5C nights, with 108.8mm of rain across a striking 15.7 days. Regulars are specific that mornings often stay dry with steady rain building through the afternoon, so an umbrella is standard advice rather than a full rain jacket for a whole-day downpour. The record: 8.6 hours of sun, a 16.9 kph wind and one of the cleanest air readings in this project, AQI 35.

Regulars describe a northeast wind pattern that picks up from mid-October and carries a bit of rain with it into November, even as the wider shift is toward the city's well-regarded cool season. Our row backs a real but easing wetness, 77.3mm of rain across 10.3 days, alongside comfortable warmth, 27.9C over 19.1C nights - noticeably milder than the peak of the wet season proper. This is also named by regulars as the start of the city's tourism high season, the cool, mostly dry stretch that makes it one of the more comfortable times of year to be outdoors here. The record: humidity 77 percent, 8.6 hours of sun and AQI 72.
This city's reputation for pleasant weather is real but it is earned after dark. Regulars call February and March pleasant with cool evenings, and in the same breath say that an outdoor day in March or April is hot and tiring - both are true. Our row reads 33.7C by day, feeling 35C, against 21C at night, and the thing doing that thirteen-degree drop is the altitude rather than the season. Air is dry for India at 49 percent humidity. Rain is almost absent at 11.4mm across 2 days, though the board expects the first showers near the end of the month. The record: 11.2 hours of sun, a 14.2 kph wind and AQI 88.
December is the month Bengaluru regulars call the best of the year - pleasant enough to move around in all day, and a relief after a climate shift that has been pushing the summer and the monsoon later and later. Our row is the mild version of a South Indian December: 27.5C days, 17.8C nights and 36mm of rain across 5.4 days, the tail of the retreating monsoon rather than a wet month. Most of the forum's December advice is about what you do with the city as a base. The Bangalore-Mysore-Ooty run takes four or five comfortable days, Ooty itself will be cold and misty so pack for it, and the hill stations are worth doing before the 20th, because tariffs double in Christmas week. The record: humidity 75 percent, 9 hours of sun and AQI 75.
Bengaluru forum threads describe February as a genuinely pleasant transition month, with good sunshine through the day and posters noting it isn't quite as warm yet as April tends to get. A recent visitor's report from a February trip specifically cited daytime highs around 32C with sunny skies, but cool evenings that called for a light layer after dark. Posters were consistent that this shoulder-season stretch, running into March, offers some of the most comfortable conditions of the year here - warm and sunny by day without the building heat of the following months, and cool rather than cold once the sun goes down.
