Traveller notes on Ko Phi Phi in December
Notes from nearby Khao Sok (133 km away)
Ko Phi Phi doesn't have its own notes for December yet — these are about Khao Sok, close enough to share the season.
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.
Other months in Ko Phi Phi
Ko Phi Phi's forum calls February one of the driest, sunniest stretches of the year — regulars who visited in January reported blue skies and no rain, and expect February to run much the same. It's busier than the shoulder months of May and June, but regulars say it's a step down from the Christmas and New Year crush.
