Hoi An is a central coast town with a clear dry and wet split. From about February to August it is dry, good for the beach and the Old Town. September to January is the wet season, and in October and November typhoons and the flooding Thu Bon River can put the Old Town under water. The typhoon season runs June to November, with the highest risk from September to November. Around the 14th of each lunar month, a full-moon lantern night fills the Old Town with lights.
