How active has the 2025 hurricane season been?

Updates published weekly
Four tropical storms and zero hurricanes so far in 2025. In the Atlantic Ocean, tropical storms and hurricanes are the most dangerous designations of storms that are collectively known as tropical cyclones. The average number of such storms per year for the prior decade (2015 to 2024) was 18. That’s the highest 10-year average on record, based on National Oceanic and Atmospheric Administration (NOAA) data dating back to 1851.

tropical storms and hurricanes per year, on average (2015–2024)

Storms are categorized primarily by wind speed. Tropical storms have maximum speeds of 39 to 73 mph. Hurricanes are on a five-part scale, in which category 3 or higher is considered a “major hurricane.” Classification is as follows:

  • Tropical depression: less than 38 mph
  • Tropical storm: 39 to 73 mph
  • Category 1 hurricane: 74 to 95 mph
  • Category 2 96 to 110 mph
  • Category 3: 111 to 129 mph
  • Category 4: 130 to 156 mph
  • Category 5: 157 or more mph

So far in 2025, four tropical storms have formed over the Atlantic Ocean and Caribbean Sea. Of those, four occurred during the official Atlantic hurricane season, which is considered June 1 to November 30. There were 18 tropical storms in all of 2024. A total of 11 reached hurricane strength winds, and five of those were classified as major hurricanes.

So far during the 2025 Atlantic hurricane season, four storms of tropical storm strength have formed.

NOAA has tracked the path of each Atlantic Ocean cyclone using various types of sources, including satellite data, aircraft reconnaissance, and ship and newspaper accounts (especially for earlier years, going back to 1851.)

The busiest year on record was 2020, when 30 storms reached tropical storm status. During that year, there were 14 hurricanes, seven of which were considered major hurricanes.

On average, 18 storms reaching at least tropical storm status took shape in the Atlantic Ocean every year between 2015 to 2024, the highest 10-year average on record.

In 2020, 30 storms in the Atlantic Ocean reached at least tropical storm strength, the most of any year on record.

Atlantic Ocean storms by type

Even without making landfall, a storm can still bring dangerous winds to coastal areas. So far in 2025, two storms have brought tropical-storm-force winds to the North American coastline. Only one, Tropical Storm Chantal in July, pushed those winds onto US land.

So far in 2025, tropical-storm-force winds have reached US soil one time.

Wind swath by storm system, as of August 4, 2025

Since 2015, about two in five of US counties have experienced tropical-storm-force winds from Atlantic storms. Among them, about 300 counties have experienced hurricane-strength winds from tropical storms.

Since 2015, 42% of US counties have experienced tropical-storm-force winds from Atlantic storms.

Counties shaded in purple experienced at least tropical-storm-strength winds (39+ mph) from at least one storm since 2015.
