Traveller notes on Mysuru in December
December is pleasant in Mysuru, and the figures regulars quote - around 18C - match our night rather than our afternoon, which runs to 27.8C; read theirs as the mornings and evenings that make the month comfortable. Rain has largely gone at 36mm across 5.4 days. The advice worth acting on is a day of the week, not a month: the palace is lit by a hundred thousand bulbs on Sunday evenings, seven to half past, extended to a full hour on Sundays and public holidays without the storytelling, while on ordinary sound-and-light nights the full illumination lasts only moments at the end. December and January are also the flower show months; the rest of the year gets the laser show. The record: humidity 75 percent, 9 hours of sun, a 14 kph wind and AQI 75.
Other months in Mysuru
Regulars are specific the city's famous Dasara festival, roughly eleven days of cultural events at the Palace, food festivals and performances across venues like Jagan Mohan Palace and Kala Mandira, wraps up with its grand procession by early October, just ahead of this month - worth checking the exact dates each year since they shift, but a visit landing right after can still catch lingering decorations and a festive mood in the city. Our row backs that warm, genuinely wet read, 28.1C over 19.4C nights, with 77.3mm of rain across 10.3 days and humidity at 77 percent. Regulars are consistent overall conditions stay pleasant this month, comfortable for palace and garden visits even with the real rain risk. Layers for cooler evenings alongside light daytime clothing remain the standard advice. The record: 8.6 hours of sun, a 13.9 kph wind and AQI 72.
Regulars are candid that this stretch of the year is among the year's least favourable weather-wise, hot and building toward the peak of summer, though still described as perfectly fine for sightseeing with sensible pacing rather than something to avoid outright. Our row backs the building heat, 34C reading as a hot 35C, over 21.3C nights, with rain almost absent, 11.4mm across 2 days, and humidity down to a dry 49 percent. Regulars are consistent that October through this month's earlier stretch is the better overall window, with conditions only becoming genuinely testing as the calendar moves deeper into spring toward April and May. The record: 11.2 hours of sun, a 14.2 kph wind and AQI 88.
Asked whether the first week of April works here, locals say yes with a timetable attached: days run 34 to 36C, so the sightseeing goes in the morning and the evening and the middle of the day goes somewhere shaded. Our row gives 35C reading as 37C, which is the same answer. The saving grace is the air - 53 percent humidity and a dew point of 17C, so this is a dry heat that lets go after dark, with nights at 23.1C. Pre-monsoon showers have started but only just, 31.9mm across 5.4 days, and they arrive late in the day. The palace and the river island are the shaded afternoon options they name. The record: 11.4 hours of sun, a 12.4 kph wind and AQI 82.
February is the tail of the comfortable season here and the Mysuru forum marks the turn inside the month: by late February the sweatshirt is redundant and it is warming day by day, though a light shawl is still worth carrying for the early morning. Light clothing otherwise. The palace is the reason most people come and the forum's advice is about the day of the week rather than the month - weekends get extremely busy, a weekday is far better, two to three hours is the right allowance, and a guide is cheap and makes the difference. The record: 31.7C days, 18.3C nights, half a precipitation day in the month, humidity 53 percent, 10.8 hours of sun and AQI 82.
