The official dates
The glossary of Mexico's National Weather Service (SMN) sets the Atlantic tropical cyclone season, which includes the Caribbean and the Gulf of Mexico, from May 15 to November 30. The Pacific season runs from June 1 to November 30. The SMN makes clear it's a statistical window: it shows when cyclones are most likely to form, not that they'll affect any given place every day.
What the 2026 forecast said
In its 2026 seasonal outlook, the SMN expected rains to begin in May and spread in June, ease off in July and pick up again in September and October. For the Atlantic it forecast cyclone activity near or below average, linked to a possible El Niño. These forecasts are general outlooks: they don't predict what will happen on a specific date or in a specific place.
How it affects day trips
- Afternoon storms: it's common for it to pour for a while and then clear. Morning trips are rarely affected.
- Cenotes: just as enjoyable in the rain; under a rock ceiling you barely notice.
- Boats and beaches (Celestún, Río Lagartos, Isla Mujeres): depend on sea conditions and may be rescheduled.
- Storm alerts: if there's an official alert, follow Civil Protection instructions.
Mary Tours doesn't refund cancellations, but you can try to change the date if the weather gets in the way.
Where to get information
Before each trip, check current alerts from the SMN and Yucatán Civil Protection. The state has an integrated risk-management program that covers weather events and provides temporary shelters when needed.
Fun facts
- The Atlantic hurricane season starts two weeks before the Pacific one.
