At first glance, the weather in Tulum in September isn’t terrible. With nice warm days and somewhat cool evenings, it might look like the ideal time to visit. But if you look closely, there are numbers that are concerning.

High humidity plus 15 rain days in the month create a very wet environment, which means even though it might be 31℃ (88 ℉), it could easily feel much warmer because your body is constantly sweating.

This makes sightseeing in Tulum extremely difficult, since most of them are either outdoor in the jungles of Tulum, or on the coastline near the beaches.

The temperature in Tulum in September might look lovely at 31 ℃ (88 ℉). But in reality, it can feel much warmer than that because of the 83 percent average humidity. At this level of humidity, you are sweating like a pig, pretty much all of the time.

This combination means you will be needing a shower right after you get out of the shower, something that is the worst when you’re on vacation.

Tourists need to be careful with the day time high temperature. It isn’t uncommon for tourists to get heatstrokes and other heat-related ailments.

In the night time, the temperature is a little bit more tolerable, especially if you are near the Tulum Beach Zone where there is a wind and breeze from the sea. You probably don’t need to pack a light jacket for September.

Precipitation in Tulum in September

The heavy precipitation is why September is not one of the best times to visit Tulum. September is in the heart of the hurricane season in Tulum and Riviera Maya. There are a total of 15 rain days in September, which is nearly half the days in the month.

Though rain is a big con of visiting Tulum at this time, it isn’t the biggest concern. As we have mentioned, September is in the middle of the hurricane season, which means there are lots of hurricanes that ravage the coast of Tulum at this time.

In 2021, Hurricane Grace annihilated the Caribbean coast of the Yucatan Peninsula, causing power outages, massive damage, and ending lots of vacations short.

And the worst is that something like this is totally unpredictable, so no matter how much planning you have done, your fate is in mother nature’s hands.

The sargassum seaweed situation in Tulum in September is a concern for visitors. Typically, the sargassum season lasts from April to August, with it peaking in around June.

And when it isn’t raining, the high temperature and humidity dehydrate you easily, which could make sightseeing uncomfortable or even deadly.

And if you get really unlucky, a hurricane could come through and completely ruin your trip!

You Might Find Fewer People To Hang Out

September is considered the low season in Tulum, which means you might not find that many travelers. While this might be a good thing if you want to avoid crowds, this might mean a lonely time for solo travelers who would like to meet others.
