The Insurance Information Institute (Triple-I) reports that wildfire risk is expanding beyond the Western United States, driven by extreme heat, drought conditions, and continued population growth in vulnerable areas. A new members-only Issues Brief reveals that more than 35,000 fires burned over 3 million acres nationwide during the first half of 2026, significantly exceeding 10-year averages for the same period. This surge underscores a shifting risk landscape where states such as Florida, Georgia, and Nebraska experienced record-setting wildfire activity, while Western states faced persistent threats from insufficient snowpack from the 2025-26 winter season.

The data indicates that wildfire exposure is increasingly a national issue rather than a regional one. Approximately one-third of all homes in the continental United States are located in the wildland-urban interface (WUI), representing more than 46 million homes exposed to wildfire risk. California remains the state with the largest concentration of homes facing extreme wildfire exposure. As populations continue to grow in these zones, the potential for catastrophic loss rises, necessitating enhanced resilience and mitigation efforts to protect lives, property, and communities.

Heat Waves and Fire Frequency

Triple-I’s research highlights a critical correlation between heat waves and wildfire ignition. Data shows that 42% of Western U.S. land impacted by wildland fires between 2001 and 2024 burned during or immediately after a heat wave. Heat waves dry vegetation and the atmosphere, creating favorable conditions for rapid fire spread. The number of heat-wave days across Western forests has nearly doubled since 2001, amplifying wildfire risks across the region.

Catastrophic Potential and Mitigation

While major wildfire events remain relatively rare, their impacts can be catastrophic. Craig Clements, Ph.D., professor of meteorology at San José State University and a Triple-I non-resident scholar, notes that catastrophic wildfires account for only 1% of all fires. These events typically occur on days with super windy or dry conditions, allowing a fire to start in the right place at the wrong time and spread out of control. Despite these challenges, advances in wildfire science, modeling, insurance innovation, and mitigation strategies are helping communities become more resilient.

Sean Kevelighan, CEO of Triple-I, emphasized that reducing wildfire losses requires collaboration among homeowners, communities, policymakers, and the insurance industry. Insurers play an important role by supporting mitigation, improving risk understanding, and encouraging investments that make homes and neighborhoods more resilient. The report concludes that community-wide commitment is essential for addressing the expanding wildfire threat.
