Weather in Tulum: Season Guide

Tulum sits on Mexico’s Caribbean coast and enjoys a warm, tropical climate all year, which is a big part of why it is a year-round destination. That said, the seasons do make a real difference to your trip, from clear sunny days to humid afternoons with a tropical downpour. Here is what to expect, month to month.

Tulum really has two seasons:

Temperatures stay fairly steady, generally between about 20°C (68°F) and 33°C (91°F). Daytime is hot and humid, often 28 to 32°C (82 to 90°F), while evenings are pleasantly warm. The humidity, more than the temperature, is what makes the rainy-season months feel intense, so light, breathable clothing is your friend whenever you visit.

Even in the rainy season, showers are often brief and pass quickly, so they rarely ruin a day. The Atlantic hurricane season runs June to November, with the highest chance of heavy weather from August to October. Direct hurricanes are uncommon, but heavy rain can briefly flood streets and lead to a canceled tour, so build a little flexibility into wet-season plans.

One weather-linked thing to know is sargassum, the brown seaweed that can wash onto Caribbean beaches. It is most common from roughly May to October, often peaking in summer, though it varies a lot year to year and beach to beach. It does not affect cenotes, pools, or the many other things to do. If pristine sand is essential to your trip, check recent beach reports.

For the best weather, come in the dry season, December through April, and book early since it is busy. For lower prices, fewer crowds, and a lush landscape, the shoulder and rainy months can be lovely, as long as you do not mind some heat, humidity, and the chance of seaweed. There is no truly bad time, only trade-offs.
