Sunshine in Tulum in September

Tulum is sunny most of the year, but September is the wettest month of the year, so cloud cover is expected on most days but there are still plenty of clear days to enjoy activities.

Also, at least 15 rainy days are expected this month.

However, the showers are usually brief and there are an average of 11 hours of daylight. This is more than enough time to enjoy pretty much anything the town has to offer.

With an average wind speed of around 4.3 miles, September is definitely not one of the windiest months, so you can also grab your beach towels and spend an evening by the sea just chilling.

Average sea water temperature in Tulum in September

The sea water temperature is typically the same all year round, with an increase of just a degree or two during the summer months.

September is also one of the hottest months, so the average sea temperature is usually around 84 degrees Fahrenheit (29 degrees Celsius).

This makes the stunning blue waters of Tulum beaches a very comfortable place to swim in if there is no sargassum.

In that case, worry not, because there are so many amazing cenotes around Tulum and many things to do in Tulum that you can really find so many great alternative options to the beach.

Do I need travel insurance in Mexico? Yes, you do! Whatever it is the way you love to travel, either by car, tour, or bus, always make sure you get travel insurance. I can never stress enough what a lifesaver it can be in unexpected situations. Although I hope I never need it, it gives me peace of mind to know that whatever happens I am covered. I have been using either World Nomads or Safety Wing. Depending on your needs or you can compare different insurance companies on this useful site, TRAVEL INSURANCE MASTER. Make sure you read carefully what’s included before making the purchase. If you want to learn more about both insurance and all your options, you can head over to my thorough post on the best travel insurance for Mexico. I am sure it will shed some light on why you need it when traveling in Mexico and how to choose the best one for you.

Sargassum Seaweed In Tulum in September

Sargassum seaweed is a problem on many Riviera Maya beaches, including the ones in Tulum.

The seaweed usually starts showing up on Tulum beaches from March/April, but August through early September is expected to have the largest quantities of sargassum.

This can definitely be a deal breaker if you’re visiting Tulum in September for its beautiful beaches.

However, the government has made efforts to clear up the seaweed and put barriers on the beaches, so you can still enjoy a great beach vacation in the later half of the month.

Also, the Cancun weather is pretty much the same in September, and you will find similar perks like fewer crowds and great deals there as well.

But the beaches there are less affected by sargassum.

Alternatively, you can try one of the Pacific Ocean beaches in Mexico, like the ones in Cabo San Lucas, and avoid sargassum altogether.

Events in Tulum in September

Independence Day

Mexican Independence Day is a big event in Tulum just like the rest of the country. The main square of the town comes alive with mariachi music and dancing as well as street vendors on the afternoon of September 15.

These festivities go on until an hour before midnight when it’s time for Grito (the cry for independence marked with fireworks and bells).

The main party starts after the Grito and goes on until the wee hours of the night.

Fall Equinox

The Autumn Equinox is a unique event of September, and one of the best places to witness it is Chichen Itza if you’re vacationing in Tulum.

El Castillo of Chichen Itza is designed in a way that the shadows create an image of Kukulkan descending the temple steps on the first day of Fall (September 22).

Just keep in mind that the cloud cover sometimes can spoil the event, so you’re better off planning it in advance by checking the weather forecast and reading the official hours announcement from the management.

Also, be sure to bring your insect repellent and try to arrive before 5 PM to see this mystical phenomenon from start to end!

Cons of Visiting Tulum in September

👎 The September temperatures and average relative humidity are quite high. This means outdoor activities can be exhausting, especially in the daytime.

👎Being its wettest month of the year, Tulum sees the highest amount of rainfall in September, so your plans might get interrupted by a tropical storm.

So make sure you always keep an eye on the weather forecast although they are not always that accurate.

On the bright side, the showers are usually very brief and the sun starts shining shortly after them, so it won’t be that much of a problem.

🏝 Take a refreshing dip in one of the cenotes

The high temperatures of September can be quite a nuisance, especially when you are exploring the town and its surroundings during the daytime.

Luckily, you will have plenty of opportunities to take a dip in the magical cenotes of Tulum.

The experience is both fun and unforgettable, in addition to being a great relief from the heat.

My favorite ones are Cenote Corazon, and Laguna Kaan Luum, but also further north towards Playa Akumal you will find Caleta Yal-Ku and Casa Cenote.

Tips For Visiting Tulum in September

Pack lots of sunscreen: The UV index of Tulum in September is around 7, which is considered dangerous for your skin if exposed unprotected to it. Such being the case, a broad spectrum SPF sunblock (ideally an environment-friendly one) will come in really handy.

Bring a hat, sunglasses, and full-sleeve shirts: Exposing as little of your skin to the UV rays as possible is another good idea.

A hat, sunglasses, full-sleeve shirts, and light long trousers or shorts will do the trick.

Here below are some packing ideas

Stay hydrated: The heat and high humidity definitely make it really important to drink lots of water, especially when you’re outside during the daytime. Bring an insulated bottle of water with you everywhere you go to make that easier.

I purchased the first one and I have to tell you with all honesty that although on one side it was great to keep the water cool, the bottle was too bulky and heavy for me.

So I switched to this one which is much lighter. And since it doesn’t keep the water cool it motivated me to drink more. 😜

Enjoy the beaches and water sports: September might be hot and humid, but it’s far from the hottest month of the year in Tulum.

Plus, the brief rainy season showers provide some relief. This means the perfect opportunity to enjoy the warm waters and chill sea breeze of the Tulum beaches! You can even book some surf lessons.

Yes, although not many people know Tulum is one of the many surfing spots in Mexico!

What is the best time of year to go to Tulum?

Tulum Mexico is a year-round destination because of its tropical climate.

But the best time to visit Tulum for your ideal type of vacation definitely does vary.

If you want to enjoy the best weather, the coldest months are best for it. The dry weather, sunny days, and pleasant temperatures make them very appealing for a vacation.

You can go between late December and early April.

The weather is perfect at this time of year, with average temperatures in the low 80s and very little rain.

The water is also warm and clear, making it ideal for swimming and snorkeling.

Just keep in mind that the winter months are the high season months, so the crowds and prices are both high during them.

When going on a Tulum trip with your family, you can’t go wrong between the months of April and May. This is when the winter months’ pleasant weather is still around and the spring break crowds are gone.

Apart from the low humidity and pleasant temperatures, you won’t have to worry about unexpected rain showers as it’s still the dry season and the rainy season is a couple of months away.

The low season (May-October) has the best month to avoid crowds and plan a budget trip. These are also the hottest and humid months.

Apart from the higher temperatures, the total rainfall in the hurricane season months (July-October) is also higher.

The shoulder season months (April-May and November through early December) are great for a little bit of everything.

The prices aren’t at their lowest, but they’re also not the highest during this time. The crowds are also fewer compared to the peak season.

November to early December are also one of the driest months, so unexpected rain showers won’t spoil your plans.

All in all, you will find plenty of activities, dry weather, clear skies, and little rain during these months.

Does it rain in Tulum in September?

Yes. Not only is September part of the rainy season, but also the rainiest month in Tulum, so at least 15 rainy days are expected in the month.

Fortunately, it’s just a brief shower most of the time. This means that you can enjoy a good vacation in September despite the rainy season.

How is Tulum in September? Final thoughts

September is an excellent time to visit Tulum for warm weather and great deals. But it can rain a lot, so this is something you must keep in mind.

This is also when there are fewer crowds than in peak season or shoulder season.

Average daytime temperatures in September hover around mid 80°Fs (26°C), with around eight hours of sunshine per day. The month also doesn’t have windy days.

This makes it ideal for spending lazy days in the Caribbean with great beach weather or exploring the archaeological site.

However, hurricane season officially runs from June to November, so be sure to check the weather forecast before booking your trip.

But also keep in mind that the weather can change unexpectedly.
