On Monday morning, the Cram Fire in central Oregon grew to 95,000 acres to become the largest wildfire nationwide so far this year, just several thousand acres away from surpassing the “megafire” threshold. While the blaze is more than half contained, the risk of concurrent wildfires in nearby municipalities is currently high.

As of Tuesday, 44 counties are under red flag warnings – an indication of increased fire risk – from the National Weather Service, representing 1.6 million people. More than a dozen major cities have a Wildland Fire Potential Index score of more than 50, indicating high wind speeds and a high ratio of dead to live fuel that could lead to rapid fire spread. A closer look at the data reveals the cities with the greatest wildfire risk this week.

To determine the cities facing the highest wildfire risk this week, Climate Crisis 247 reviewed data from the U.S. Geological Survey. Cities were ranked based on average Wildland Fire Potential Index for July 23, 2025. Supplemental data on maximum temperature are based on forecasts from the NOAA. Only cities with at least 50,000 residents were considered. Data on population and home value are from the U.S. Census Bureau.
