Traveller notes on Khao Sok in January
Notes from nearby Khao Lak (46 km away)
Khao Sok doesn't have its own notes for January yet — these are about Khao Lak, close enough to share the season.
Khao Lak's forum rates January among the best months of the year — hot, sunny days around 32-34°C, clear blue skies, with rain minimal. Regulars flag online forecasts as unreliable here, routinely showing thunderstorm icons that rarely translate into more than an isolated hour-long shower, and note evenings can turn cool enough for a light cardigan.
Other months in Khao Sok
Khao Sok's forum calls December squarely in the dry season, which runs through to April — regulars staying in the park's treehouses report warm days in the high 20s to low 30s°C and mild nights in the low-to-mid 20s. It's a genuinely humid rainforest even in the drier months, so don't expect crisp, dry air — just a lot less rain than the wet season that runs mid-April to early December.
