The National Weather Service has logged 953 storm reports in Hawaii County since 1955, with 7 deaths and 8 injuries and about $98.7 million in reported damage. The strongest on record here was an F1 tornado on March 20, 1980.

Source: NOAA Storm Events Database, county-based reports through Jun 2, 2026. Tornado records start in 1950, hail and wind in 1955, and floods and other storm types in 1996, so older decades undercount. Damage is in dollars of the year it happened and is often an estimate. Winter storms, heat and hurricanes are logged by forecast zone, not county, so they are not counted here.

Since 1958, 0 hurricanes and 3 tropical storms have passed within 65 miles of the center of Hawaii County, 3 of them since 1950. The strongest was Tropical Storm Iselle (2014), with top winds near 65 mph about 57 miles away.

Source: NOAA National Hurricane Center best-track records (HURDAT2), 1851 to 2025 for the Atlantic and 1949 to 2025 for the eastern Pacific. A storm counts if its track passed within 65 miles of the county's center while it was a tropical storm or hurricane. Strength is the storm's top sustained wind at that point, not the wind measured in the county. Older storms over the open sea were sometimes missed.

National Flood Insurance Program (NFIP) records only; private flood policies are not included. Home counts as of Aug 3, 2026. Since 2021 NFIP prices each home separately under Risk Rating 2.0, so your price depends on the building, not the county. Ask an agent for a quote.

Older homes and mobile homes usually suffer more damage in storms, floods and earthquakes, and can cost more to insure. If you are buying, ask about roof age, foundation bolting and any retrofits.
