Best Time to Visit Cancún: A Month-by-Month Guide
When to visit Cancún and the Riviera Maya: dry season vs. rainy season, hurricane season, sargassum seaweed, crowds and the best months for each kind of trip.
Updated November 12, 2026 · By the RoamPlanned team
Short answer: December through April is the most reliable time for sunny beach days in Cancún, with lower humidity and less rain. It is also the busiest and most in-demand period. Late April, May and November are good shoulder months, with warm water and thinner crowds. The rainiest, most humid stretch is roughly June through October, which overlaps the Atlantic hurricane season.
Cancún's seasons at a glance
| Months | Weather | Good to know |
|---|---|---|
| December–April | Dry season: mostly sunny, breezy, lower humidity | Peak demand around Christmas, New Year's and US spring break (March). Book early. |
| May–June | Hot and increasingly humid; rain showers become more frequent | Fewer crowds. Sargassum seaweed can appear on some beaches from spring into summer. |
| July–October | Hot, humid, the wettest months, with short heavy downpours | Peak of hurricane season is roughly mid-August to October. Summer school holidays bring families in July. |
| November | Rain tapers off, humidity drops | A quieter month before the holiday rush, still inside hurricane season until November 30. |
Hurricane season
The Atlantic hurricane season runs from June 1 to November 30, and activity typically peaks from mid-August through October. Most weeks in that window pass without a storm, but if you travel then, choose refundable or flexible bookings where you can, watch the National Hurricane Center's forecasts before you go, and consider travel insurance that covers weather. Insurance usually has to be bought before a storm is named to cover it.
Sargassum seaweed
Since the 2010s, large mats of sargassum seaweed have reached parts of the Mexican Caribbean, mostly from spring through late summer. The amount changes from year to year and from beach to beach, and many resorts clear their sand each morning. If seaweed is a concern, look at Playa Norte on Isla Mujeres or the Cancún Hotel Zone's north-facing stretch, which face away from the open Caribbean, and check recent reports close to your trip.
Best time for specific trips
- Beach weather and calm seas: December through April.
- Better value and fewer crowds: late April to early June, and November into early December (avoiding Thanksgiving week).
- Whale sharks: tours from Isla Mujeres and Holbox run in summer, roughly June through September.
- Sea turtle nesting: turtles nest on Riviera Maya beaches from about May to October. Keep a respectful distance and follow local guidance.
- Mayan ruins: the dry, cooler months make Tulum, Cobá and Chichén Itzá more comfortable. Go early in the day in any season.
Weather tips for any month
- The sun is strong year-round. Bring reef-safe sunscreen, a hat and plenty of water.
- Summer rain usually comes as short afternoon storms, so plan beach time in the morning.
- Check the beach flag system before swimming. Some east-facing Hotel Zone beaches have strong surf and currents.
