Conditions on this page are recalculated from the latest forecast every time it is opened, for the current date in the location's own time zone.
Editorial seasonal guidance for Bangkok where it has been written, plus daylight, midday sun angle and golden-hour length calculated for every month from Bangkok's coordinates. This page does not publish monthly temperature or rainfall averages: the site has no verified climate dataset, and it no longer generates one. For decisions inside the next week, the live 7-day ranking on the Bangkok weather page is the right tool.
Any weather decision in Bangkok starts from the light budget. In September the location gets about 12 h 7 min of daylight, with the sun peaking 76° above the horizon — that sets how warm afternoons run, how long outdoor plans stay viable and how much usable photographic light the day contains. The scores above layer the live Open-Meteo forecast on top of that baseline.
Daylight, midday sun angle and golden-hour length below are calculated for Bangkok's own coordinates (13.76° N, 100.50° E) on the 15th of each month. These are solar geometry, not climate averages.

Scores are capped by dealbreakers — heavy rain, dangerous wind, thick fog or hazardous UV pull a day down no matter how pleasant the rest of the numbers look. Forecast data is Open-Meteo; solar and lunar values are computed for Bangkok's own coordinates and time zone. Full details on the methodology page.
