Regulars are specific hotels and restaurants across the region reopen for the season right around the end of August, this month also capturing the Onam festival in its first ten days for anyone whose trip lines up. Our row backs that hot, genuinely wet read, 28C reading as a scorching 33C, over 24C nights feeling 28C, with a substantial 190.9mm of rain across 23.1 days and humidity at 87 percent. Regulars are honest experiences genuinely vary, most describing mostly sunny days with random afternoon showers while one visitor's own trip turned out very wet with hardly a dry day the whole time. The sea stays genuinely rough for most of the month, not pleasant for swimming regardless of how sunny a given day looks. The sea sits at 27.2C. The record: 9.5 hours of sun, a 18.5 kph wind and AQI 39.

Regulars are consistent that this month runs genuinely hot and humid, with the standard advice built around timing rather than avoidance: resort pools or the sea for relief during the worst of it, roughly noon to 3pm, with sightseeing shifted to the cooler hours either side. Our row backs the intensity directly, 32C reading as a real 38C at 78 percent humidity, over 25.5C nights, with 91.9mm of rain across 17.2 days. Regulars who've returned multiple Aprils describe the heat as real but not a dealbreaker, with air-conditioned accommodation making the difference between an uncomfortable trip and a manageable one. The sea holds a very warm 30.1C. The record: 11 hours of sun, a 14.8 kph wind and AQI 74.

December opens the Kerala dry season and regulars put November to February down as the good stretch, pleasant and clear, with at least one visitor calling it remarkably hot rather than pleasant. Our row leans their way: 29.7C reading as 34C over nights that stay at 23.5C. The advice worth carrying is about the water rather than the sky. The sea off this cliff is rough at the best of times and never really calm, rain or no rain, so swimming means staying inside the area the lifeguards have flagged. Rain is not the issue in any case - 77.3mm across 8.6 days. The record: humidity 77 percent, 9.8 hours of sun, a 29.2C sea and AQI 70, the figure here most worth checking before a long stay.

March closes the Kerala season - regulars say come between November and February or March, because April is another thing entirely and the heat runs March to May. Our row reads 32.8C as 38C at 73 percent humidity, one of the hottest figures in this collection, over nights of 24.8C that feel like 29C. Their practical rule is a time of day rather than a packing list: after about eleven in the morning it is hot enough that even a short walk is work. Being on the coast softens it compared with inland Kochi, and the cliff catches a slight breeze, which is why that is where everyone sits. The sea offers no relief at 29.2C. The record: 34.2mm across 9.5 precipitation days, 11.1 hours of sun, a 15.7 kph wind and AQI 81.
