When do most wildfires occur in Pennsylvania?

Most wildfires in Pennsylvania occur during spring and autumn due to specific environmental conditions that favor the ignition and spread of fires during these seasons. In spring, the landscape often experiences a buildup of dry leaves and vegetation from the previous fall, creating potential fuel for fires. Additionally, increasing temperatures and lower humidity levels can contribute to conditions that are conducive to wildfire outbreaks.

In autumn, the situation is similar, as fallen leaves and drying plants create additional fuel sources. As temperatures start to drop, the humidity can also fluctuate, further stressing the dry vegetation. These factors combine to create a higher likelihood of wildfires occurring during spring and autumn compared to other seasons when moisture levels are generally higher, and the vegetation is less prone to ignition. This seasonal tendency highlights the importance of being vigilant and aware of fire safety practices during these critical times.
