In the Atlantic and Eastern Pacific, hurricane season is officially over on November 30 each year.

Quick Scoop

  • Atlantic hurricane season: June 1 to November 30.
  • Eastern Pacific hurricane season: May 15 to November 30.
  • Most activity happens August–October, with September usually the peak.
  • Storms can still form outside these dates, but it’s less common.

So if you’re asking “when is hurricane season over?” in the general, official sense, the answer most people and agencies use is November 30 for both the Atlantic and Eastern Pacific basins.

Why people still talk about it after November

Even once the calendar says the season is over, forecasters sometimes keep an eye on the tropics into December because the ocean can stay warm enough to support a late storm, especially in busy or unusually warm years. In recent seasons, there have been public discussions and debates about whether it’s “really over” yet, especially when the last few weeks have been quiet but conditions still look marginally favorable.

You’ll often see meteorologists phrase it as: “The official season ends November 30, but that doesn’t flip a magic switch.”

Around the world

If you’re outside the Atlantic/Eastern Pacific, the timelines shift:

  • Australian/Southwest Pacific: roughly November to late April.
  • Northwest Pacific “typhoon season”: activity can occur year‑round, with more active periods rather than a strict start–end date.

So globally, the answer to “when is hurricane season over?” depends on your basin, but for the most searched one—the Atlantic—it’s November 30. TL;DR: Officially, hurricane season is over on November 30 in the Atlantic and Eastern Pacific, though a rare storm can still form outside those dates.
