Hurricane season dates at a glance
| Basin | Starts | Ends |
|---|---|---|
| Atlantic | June 1 | November 30 |
| Eastern Pacific | May 15 | November 30 |
| Central Pacific | June 1 | November 30 |
Official season calendars repeat annually, including 2026. Dates do not predict today’s storm activity.
Atlantic hurricane season: June 1 to November 30
The Atlantic calendar includes the North Atlantic, Caribbean Sea and Gulf of Mexico. It is the relevant basin for many questions about Florida, the U.S. Gulf Coast and Caribbean travel. A destination can have its own local rainfall and marine hazards, so a basin calendar cannot answer whether a specific trip or coast is safe.
Eastern Pacific hurricane season: May 15 to November 30
The Eastern Pacific starts earlier than the Atlantic. For Mexico’s Pacific coast and Baja California, read the Eastern Pacific outlook and compare it with SMN / CONAGUA notices. An Atlantic forecast alone does not describe a Pacific system. The dedicated Eastern Pacific guide explains formation outlooks and active advisories.
Central Pacific hurricane season: June 1 to November 30
The Central Pacific shares the Atlantic dates but uses its own outlooks and cyclone products. For Hawaii, read NHC / CPHC information alongside the local National Weather Service. A system can cross basin boundaries; use the area and responsible center shown on the current bulletin.
When does hurricane season peak?
NHC climatology places the Atlantic peak around September 10, with most activity from mid-August to mid-October. The Eastern Pacific typically peaks in late August. These are historical basin patterns, not predictions of a landfall, the number of storms this year, or conditions at your location. There can be quiet days near a peak and active systems near the season’s ends.
Can hurricanes form outside the official season?
Yes. The start and end dates summarize the usual period of activity; they do not prevent a cyclone from forming at another time. Check the latest official outlook and warnings when there is a weather concern, including outside the calendar. Do not label a system inactive solely because a date falls outside the season.
Does this cover typhoon and cyclone seasons worldwide?
No. These three rows describe NHC / CPHC hurricane basins. Japan and the Philippines use typhoon information; India and Australia use their regional cyclone products. Australia’s official cyclone season is November 1–April 30. Our country directory links to the agency for each location rather than applying the Atlantic calendar everywhere.
Use dates for preparation, then read the current advisory
First identify the basin. Next check the outlook’s issue time and period, then open any active storm advisory and your local warning products. A formation probability describes development over a stated time window; a forecast track describes an existing system. This site checks NHC data every five minutes while open, but only the agency can issue a new forecast.
Frequently asked questions
When does hurricane season start and end?
Atlantic and Central Pacific: June 1–November 30. Eastern Pacific: May 15–November 30.
Is hurricane season the same every year?
The official basin calendar repeats each year. Actual storm activity, timing and impacts vary.
When is hurricane season in Florida?
Florida uses the Atlantic season, June 1–November 30. For current conditions, check NHC and local NWS alerts.
When is hurricane season in Mexico?
For the Pacific coast, May 15–November 30; for the Gulf and Caribbean, June 1–November 30. Consult SMN for local notices.
