Southern Oregon Wildfire Weather Season: What to Expect

Every summer, Southern Oregon braces for wildfire season. The combination of hot temperatures, low humidity, and the region's complex terrain makes this one of the most fire-prone areas in the Pacific Northwest.

Understanding Fire Weather

Fire weather in Southern Oregon is driven by several key factors:

**Hot, Dry Summers**: The Rogue Valley and Umpqua Valley experience some of Oregon's highest summer temperatures, regularly exceeding 100°F. Low humidity — often dropping below 15% on hot days — creates tinderbox conditions.

**Offshore Wind Events**: Known locally as "Offshore Flow" or "East Wind" events, these dry winds blow from the high desert toward the coast, dramatically increasing fire danger. They can push existing fires miles in hours.

**Lightning Storms**: Late-season thunderstorms in August and September can ignite multiple fires simultaneously across the region.

Staying Prepared

1. **Sign up for emergency alerts** through your county's emergency notification system

2. **Create a defensible space** of at least 30 feet around structures

3. **Prepare a "go bag"** with essential documents and supplies

4. **Know your evacuation routes** — have primary and secondary options
