Rain season
Bangkok's wet season (May–October) brings daily tropical rain, mostly in the afternoon — intense for 30–90 minutes, then clearing. September and October are the most challenging months: accumulated rainfall saturates the city's drainage, and tidal effects on the Chao Phraya River amplify flood risk. The dry season (November–April) is reliable — virtually zero chance of rain.
