FWI
  • Extreme (>30)
  • Very high (20-30)
  • High (10-20)
  • Medium (5-10)
  • Low (0-5)

The Fire Weather Index (FWI) is calculated daily using the ERA5 hourly reanalysis.

FWI breaking records show areas where daily FWI values are breaking historical records (1950-2024) for the same day (black contours, map on the left), and for the entire fire season (red contours, map on the right). In both cases, colormap represents the number of days with FWI values breaking record since the fire season onset.

Maps are updated everyday at 5:00 am and correspond to the conditions from 6 days ago due to the availibility of ERA5 reanalysis data.
