In Brief

When is the best time to visit Cancún?

The best time to visit Cancún is December to April - the dry season, with sunny skies, low humidity, calm seas and little to no seaweed or hurricane risk. It's peak season, so December-January and the spring-break weeks are the busiest and priciest. April and late November are the sweet spots for that same great weather at lower rates. The hurricane season runs June to November and peaks in September, and sargassum seaweed is heaviest from about May to October.

Key takeaways

  • Best weather: December to April - dry, sunny, calm seas and minimal seaweed.
  • Cheapest months: May-June and September-November, once the winter crowds leave.
  • Hurricane season: June to November, peaking in September.
  • Seaweed (sargassum): typically heaviest May to October - lightest in winter.

Best time to visit Cancún: FAQ

The timing questions travelers ask most before booking.

The cheapest months are the low season of May-June and September-November, once the winter and spring-break crowds have gone. September and October are the very cheapest - but they're the peak of hurricane season and often the heaviest for seaweed, so you trade price for reliability. For low prices with better weather, target May, early June or the second half of November before the holiday surge.

Hurricane season runs June 1 to November 30, with the highest risk in September and early October. Most summer and autumn trips see nothing worse than short afternoon storms, and a direct hit in any given week is uncommon - but if you're travelling in the September-October peak, keep your itinerary flexible and buy travel insurance. December to April sits safely outside the season.

Sargassum seaweed is typically heaviest from May to October, and lightest from December to April. Amounts vary year to year and beach to beach - the Caribbean-facing shores get more than the sheltered bays of Isla Mujeres and the north-facing beaches. Big resorts rake their beaches daily in season. If a pristine white-sand beach is the priority, come in the winter dry season.

September and October carry the highest hurricane risk, the most rain and often the heaviest seaweed, so they're the months to approach with caution. The other stretch to plan around is the late-December holiday peak, when prices spike and resorts sell out. For great weather without either issue, come between January and April - just note that March brings the spring-break crowds.

For the December-April high season - especially Christmas-New Year and the March spring-break weeks - book flights and resorts three to five months ahead, as the best all-inclusive deals sell out early. For the summer and autumn low season, four to six weeks is usually enough. Flights land at Cancún International (CUN), the main gateway for the whole Riviera Maya.

Cancún is warm and tropical all year, with highs of 28-33°C. December to April is dry, breezy and comfortable; May to October is hotter, more humid and wetter, with afternoon storms and the hurricane and seaweed seasons. Sea temperatures stay swimmable year-round (26-29°C), so the main variables are rain, storm risk and seaweed rather than warmth.

Staying in Cancún? Book the area before the hotel

Picking the month is half of the decision. The other half is the area, because that is what sets how far you walk and what a room costs in Cancún. These go into the detail:
