Wildland Firefighting Practice Exam

During which hours do most wildland fires start and spread the fastest?

1. 0800 to 1000

2. 1000 to 1600

3. 1600 to 1800

4. 2000 to 2400

The correct answer is: 1000 to 1600

Wildland fires typically start and spread the fastest between 1000 and 1600 hours. This period aligns with peak solar heating, which raises temperatures and decreases relative humidity during the day, creating optimal conditions for fire development and spread. As temperatures rise, the materials available for combustion—such as dead vegetation and other fuels—become drier and more easily ignitable. Additionally, wind patterns can strengthen during the afternoon, contributing to the potential for rapid fire spread. Understanding this timing is crucial for effective fire management and response strategies.
