Fire Danger Index Detail

These indices are not a replacement for the official SAWS FDI. The SA Weather Service FDI is updated once daily from the SAWS map image — accuracy depends on map image quality. The Calculated FDI is updated throughout the day from third-party weather data (Open-Meteo, WeatherAPI.com). Always verify with official sources.

SA Weather Service FDI

How this works: The SAWS FDI map image is downloaded and the pixel colours at the Broederstroom area are sampled directly — one point on the North West province side and one on the Gauteng side of the provincial boundary. Each colour is matched to an FDI category and a blended value is calculated (65% NW side, 35% Gauteng side), with a conservative adjustment toward the higher index when the two sides differ.
