Hurricanes (also called tropical cyclones in some parts of the world) are among the most destructive weather events on Earth. Beyond the headline wind speeds, the biggest risks often come from storm surge and freshwater flooding, which can affect areas well inland.
This post is a reference-style roundup of confirmed hurricane facts and statistics from credible sources like NOAA and the National Hurricane Center (NHC). I update it when authoritative agencies publish new figures.
Interesting Facts About Hurricanes (2026 Update)
Quick Hurricane Facts (high-level takeaways)
- Atlantic season dates: June 1 through November 30 (official season).
- Average Atlantic season activity (1991–2020 normals): 14 named storms, 7 hurricanes, and 3 major hurricanes.
- Biggest cause of direct U.S. hurricane deaths is water: storm surge and flooding account for the overwhelming majority of direct fatalities.
- Atlantic hurricane season dates (official): The Atlantic basin’s official hurricane season runs June 1 to November 30.
- What an “average” Atlantic season looks like (modern climate normals): Using the 1991–2020 climate normals, the Atlantic averages 14 named storms, 7 hurricanes, and 3 major hurricanes (Category 3+).
- How hurricanes are named (and when the modern system began): In the Atlantic, the U.S. began using female names in 1953. The Atlantic lists later shifted to include both male and female names in 1979.
- Retired hurricane names are a real thing (and the list is long): When a storm is especially deadly or costly, its name can be retired and not used again in the basin.
- Deadliest Atlantic hurricane on record: NOAA’s historical summary identifies the Great Hurricane of 1780 as the largest loss event in the Atlantic record, with estimates around 22,000 deaths in the Lesser Antilles.
- Deadliest U.S. hurricane on record: The 1900 Galveston Hurricane remains the nation’s worst weather disaster, with more than 8,000 deaths commonly cited in official accounts.
- Deadliest tropical cyclone on record globally (commonly cited): The Bhola Cyclone (1970) is often cited among the deadliest tropical cyclones in recorded history, with estimates of 300,000 to 500,000 deaths.
- Costliest U.S. hurricane on record (NOAA dataset): In NOAA’s damage database, Hurricane Katrina (2005) is listed as the costliest U.S. hurricane on record (inflation-adjusted totals in the dataset).
- Strongest sustained winds (commonly cited for the Western Hemisphere): Hurricane Patricia (2015) reached 215 mph maximum sustained winds at peak intensity (as summarized by NHC reporting and widely referenced in meteorological summaries).

- Longest-lasting tropical cyclone (record context): Cyclone Freddy (2023) is recognized as the longest-lasting tropical cyclone in Guinness World Records, surpassing the long-held record associated with Hurricane/Typhoon John (1994).
- In the U.S., water is the biggest killer in tropical cyclones: Research summarizing U.S. fatalities (1963–2012) found that nearly 9 out of 10 direct deaths were due to water, with storm surge ~49% and freshwater flooding ~27% of direct deaths.
- How tropical cyclones are classified (by wind speed): Tropical cyclones are categorized by sustained winds—from tropical depression to tropical storm to hurricane—and “major hurricane” (Category 3+) begins at 111 mph.
Classification of Tropical Cyclones (by sustained wind speed)
- Tropical Depression: 38 mph (33 knots) or less
- Tropical Storm: 39 to 73 mph (34 to 63 knots)
- Hurricane / Typhoon / Cyclone: 74 mph (64 knots) or higher
- Major Hurricane: 111 mph (96 knots) or higher (Category 3, 4, or 5 on the Saffir–Simpson scale)
