A detection is a heat signal seen from space, not burned area or a count of separate fires.

Usual (median): 9.4
Rank: 3 of 26

Raw satellite data would say 40.0× the usual, because it joins MODIS and VIIRS as they are and VIIRS sees far more small fires. Corrected, it is 2.1×.

How sure is this?

Daily fire weather: the Open-Meteo weather forecast, most reliable for the first 3 days.
Next 7 days: tested on 6 past years, the model ranked a week that turned busy above a quiet one 86 times in 100 (the season alone: 72).
Next 3 months: the real total fell inside the likely range 76 times in 100 (the usual range alone: 71).
Beyond 3 months: the usual year. 8 in 10 past years fell inside the grey band. Weather that far ahead is not known.
