Mid-Year Billion-Dollar Disasters

The U.S. experienced 12 billion-dollar weather and climate disasters from January to June 2026, causing at least $31.9 billion in damages and 183 fatalities. This period ranks fifth for the most events in the first half of any year since 1980. Severe storms were the dominant disaster type, accounting for eight of the 12 events. Historically, the average number of such disasters per year has risen from three in the 1980s to 20 events annually between 2016 and 2025, with the average time between events shrinking from 82 days to 16 days in the same comparison.

• In the first six months of 2026, the U.S. recorded 12 billion-dollar weather and climate disasters, resulting in at least 183 deaths and $31.9 billion in damages. This timeframe ranks as the fifth-highest number of events for the January-June period since records began in 1980, significantly exceeding the long-term average of approximately five events.
• Severe storms were the primary driver of billion-dollar disasters in early 2026, accounting for eight of the 12 events. These storms, including tornado outbreaks in the central U.S. from March to June, are the most frequent type of billion-dollar disaster in the U.S. since 1980 and the leading cause of weather-related power outages.
• The most expensive event of 2026 so far was the Central and Southern Severe Storm (April 23-29), causing $6.8 billion in damages. The deadliest was the Central and Eastern Winter Storm, which caused 171 deaths, representing the vast majority of the 183 total fatalities from billion-dollar disasters in the first half of the year.
• There has been a dramatic increase in the frequency and density of billion-dollar disasters since 1980. The annual average rose from about three events in the 1980s to 20 events per year between 2016 and 2025. Consequently, the average time between events decreased from 82 days in the 1980s to 16 days during the 2016-2025 period, reaching a low of 10 days in 2025.
• Since 1980 and through June 2026, the U.S. has seen 438 billion-dollar weather and climate disasters, causing an estimated 17,377 deaths and costs exceeding $3.2 trillion. This trend is attributed to the increased frequency and intensity of extreme weather combined with higher exposure of people and infrastructure in floodplains, coasts, and fire-prone areas.
