מזג האוויר בקודיאקנל בדצמבר

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 monsoon season across the Western Ghats, with Kodaikanal seeing more rainy days than the rest of the year, though posters are consistent that rain doesn't fall continuously and conditions overall stay genuinely pleasant. One visitor's family reported daytime temperatures around 25C and nighttime lows near 15C, with intermittent showers rather than day-long downpours. Posters note August counts as off-season here, meaning lighter crowds alongside the wetter weather, and consistently recommend checking for rainfall alerts a few days ahead since conditions can shift. Posters generally rate August as genuinely rainy but still enjoyable for a Kodaikanal visit, an umbrella and flexible plans the main preparation needed.

Forum posters count February among the best months to visit this hill station: cool days with limited sunshine and genuinely chilly nights, but the misty, cold atmosphere is repeatedly called magical rather than a downside, and crowds are thin compared to the main holiday season. As a hill station well above the surrounding Tamil Nadu plains, Kodaikanal runs noticeably cooler than the lowland cities most visitors are arriving from - regulars advise packing real warm layers, since people expecting South Indian heat are routinely caught off guard by how cold the evenings get.
