Traveller notes on Khao Sok in April

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.
