Traveller notes on Ko Phi Phi in January
Notes from nearby Krabi (40 km away)
Ko Phi Phi doesn't have its own notes for January yet — these are about Krabi, close enough to share the season.
Krabi's forum rates January as the west coast's dry-season sweet spot — generally the best weather window of the year — while being honest that some years still bring unseasonal rain or cloud through the month. Regulars point out the west coast (Krabi, Phuket, Koh Lanta) reads more reliable than the east coast islands during this same stretch.
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.
