Background

While the "fire season" in Idaho varies every year based on fire weather conditions, most wildfires occur from June to September.[3] Fire activities normally increase in July and August because of drier conditions, hotter temperatures, and more lightning strikes from thunderstorms. However, wildfire severity can vary every year based on preseason conditions such as snowpack and the overcrowded growth of vegetation and dying trees.[4]
