How it works and how accurate it is
26/28rainy days (2025 rainy season) were forecast in advance
13/39times rain was forecast but the station measured none
~1/2of hourly forecasts are wrong, so we do not give a time when rain stops
Method in detail
Rain chances come from the hourly rainfall of a weather model (Open-Meteo), converted with a table checked against rain actually measured at the Nha Trang weather station. "Unlikely / possible / likely" reflects how often the station measured at least 1 mm of rain when the model gave a similar forecast.
Check over the rainy season (October-December 2025): the model caught 26/28 rainy days and was wrong 13/39 times when it forecast rain. In the dry season (June-October 2026) the model forecasts too much rain (38/52 rain forecasts were wrong) because thunderstorms usually stay over the mountains to the west, so we lower the rain level in the dry season.
We do not give an exact time for rain to start or stop: checked in 6-hour blocks, about half of the model's rain forecasts did not happen at the station. So the forecast is split only by part of the day.
This is a self-calculated reference index, not an official weather forecast. For heavy rain, typhoons and tropical depressions, follow the bulletins of Vietnam's South Central regional hydro-meteorological centre.
