The most common cause is thunderstorms.

  Sometimes yes, you are right, but this depend on the area. I remember a study from the north of Spain concluding that only around 11% of the wildfires with known cause were by lightning. Most people would guess a much higher percentage if asked. In 2020, some places here experienced a 94% less wildfires than in previous years also. The only variable changing was humans. Everybody at home by covid19 = no wildfires. To fellow Canadians with better direct experience here, are this hot waves being coupled with heavy (or dry) storms?
