Tulum is warm all year, so you can always go. What changes with the season is rain, sargassum, crowds and prices.
December to April · dry season
The best weather of the year: less rain, less humidity and sunny days. It is also high season, with more visitors and higher hotel prices, especially at Christmas, New Year and Easter week. Book early.
May and June · heat
The hottest and most humid months. There are usually fewer people than in winter. In many years, sargassum starts reaching the coast around this time.
July to October · rain and hurricanes
The Atlantic hurricane season runs from June 1 to November 30, with the most activity between August and October. It rains more, though usually in short afternoon showers. Prices drop. If you travel in these months, get travel insurance and follow Civil Protection alerts.
November · transition
Rain eases, sargassum usually drops and high season hasn't started yet. A good time for nice weather at reasonable prices.
About sargassum
Sargassum is a seaweed that reaches Caribbean beaches, mostly between spring and summer. It varies a lot from year to year and beach to beach. Before choosing a beach or beachfront hotel, check the sargassum alert map. Cenotes are not affected.
