Traveller notes on Ko Chang in February
Other months in Ko Chang
Ko Chang's forum is honest that June is historically one of the wettest months on the island, and which kind of week you get - mostly sunny with a passing shower, or grey and wet for days - genuinely comes down to luck. Posters were consistent that it's rare for rain to last an entire day; more often it's a short afternoon shower or a late-night thunderstorm. The trade-off for accepting rougher seas and real rain risk is a much quieter island and waterfalls running at their most spectacular - some visitors specifically choose this season for the jungle and falls over the beach.
Forum posters describe December as close to ideal here - sunny, not too hot, minimal rain expected, with the sea reported flat, clear and calm under bright blue skies from November onward. Daytime highs are commonly described in the low-30sC, with overnight temperatures posters call cool by tropical-island standards - typically settling in the low-to-mid-20sC, though a windier night can feel noticeably chilly to some visitors, prompting a few to skip the air conditioning and just leave the window open instead. December is peak season across Thailand, so posters note it's also one of the busier, pricier months, with the island reported quieter only in the first couple weeks before the holiday rush sets in.
