September Is Peak Hurricane Season. Why Is That?

Hurricane Florence made landfall Friday morning in North Carolina. While people along large swathes of the Eastern Seaboard have been dreading the storm for days, you can say one thing: it arrived right on time.

We are smack-dab in the middle of Atlantic hurricane season, which runs from June 1 to November 30. Nearly all tropical storm activity in the Atlantic basin occurs between those dates.

The season peaks between August and October, with September 10 as the day you’re statistically most likely to find a tropical cyclone somewhere in the Atlantic basin.
