The raw record jumps in 2012 when VIIRS arrives; the harmonized record does not.

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.
About this report
Counts are NASA FIRMS active-fire detections (MODIS since 2000, VIIRS since 2012) put on one scale (harmonized), so years before and after 2012 can be compared.
A detection is a heat signal seen from space, not burned area or a count of separate fires. Clouds and smoke hide some fires; hatched weeks had no satellite observation.
Weather: Open-Meteo forecast and NASA POWER history. Forecast reliability is from tests on past years the models never saw.
