In 2023, Hurricane Idalia was the only hurricane to make landfall in the U.S. It made landfall on Aug. 30 as a Category 3 hurricane in the Big Bend region of Florida. At one point, Idalia was a Category 4 hurricane.

Idalia, Franklin (Category 4) and Lee (Category 5) were the season’s three major hurricanes.

It was a very early start to the season. The first storm formed on Jan. 16 and was an unnamed subtropical storm. It made landfall in Nova Scotia.
