California is unfortunately prone to wildfires year round (due to climate change). The combination of dry vegetation and Santa Ana wind events create the conditions for wildfires to ‘explode’ and even create their own weather (Firenados, etc.).
For up-to-date information on wildfires in California, there is no better organization than Watch Duty.
