Hurricane season officially starts at different times depending on the basin, but for most people in the U.S. the key date is June 1.

Quick Scoop

  • In the Atlantic (U.S. East Coast, Gulf of Mexico, Caribbean):
    Hurricane season runs from June 1 to November 30 each year.
  • In the Eastern Pacific (west coast of Mexico/Central America):
    Hurricane season runs from May 15 to November 30.
  • Peak activity in the Atlantic is mid‑August through late September , with early– to mid‑September as the most active stretch.
  • Other global basins have their own “seasons,” for example:
* Northwest Pacific typhoons: **year‑round** , most between May and October.
* Southwest Pacific (near Australia/NZ): about **November 1 to April 30**.
* Several Indian Ocean seasons span much of the year in two main windows.

So, if your question is “when does hurricane season start?” and you’re in the U.S. Atlantic or Gulf region, plan as if it starts June 1 , with real ramp‑up beginning in August.
