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.
