Wetter in Munnar im Dezember

December is the middle of the Kerala season - regulars put the good window at mid-November to mid-February and the best of it at mid-December to mid-January - and that is the problem as much as the recommendation. Hotels fill through December and January, so the advice is to book as soon as the dates are fixed. The weather is sunny and mostly dry, with our row giving 55.9mm across 6.3 days, and their figures of about 32C by day and 23C at night almost exactly ours. What they flag is humidity, which on this coast stays high whatever the rain does: our row says 81 percent, turning 31.8C into a feels-like 38C. The record: 9.7 hours of sun, a 29.9C sea and AQI 91.

Forum posters describe August as peak monsoon in Munnar, with cool, pleasant temperatures generally in the high-teens to low-20sC and heavy, frequent rainfall, though posters are consistent that it isn't a continuous downpour - proper planning still allows for outings between showers. Posters flag real logistical risks specific to this hill-station setting: landslides and roadblocks are a genuine possibility, hill roads get slippery, and driving is best kept to daylight hours only. On the upside, posters describe Munnar at its greenest and mistiest in August, with waterfalls running at full flow, noticeably thinner crowds, and better hotel rates than the peak season. Posters generally rate August as wet and logistically more demanding but visually the most dramatic time to see Munnar, workable for travelers prepared for the monsoon.

Forum posters describe February as sitting near the tail end of Munnar's Nov-Feb cool season - daytime is warm and pleasant but far from hot, while evenings turn genuinely cold once the sun goes down, with old Munnar and Devikulam specifically named as the coolest spots in the area. Posters consistently call December-through-February the peak, most pleasant season here, with minimal rain and lush, evergreen tea-plantation scenery as the payoff. The standard packing advice given the day-to-night swing is to bring warm layers regardless of how mild the daytime forecast looks, since evening and early-morning cold can catch visitors off guard.
