Why Thailand's Rain Always Hits at 3pm | RainViewer Blog

TL;DR: Thailand’s afternoon rain is not luck. It is a convective cycle that repeats almost every day of the wet season. The ground stores heat from early morning; hot air rises and condenses into cloud From the first heating to a fully built storm cloud takes roughly four to six hours Convective rain is heavy but short: the cold downdraft cuts off its own energy supply Some very hot days stay dry because the air aloft is too dry or capped by a warm layer The daily pattern repeats, but the spot where the rain lands does not Anyone who has lived in Thailand long enough knows the pattern.
