Weather in Tulum in August
August in Tulum is peak tropical Caribbean. Expect average highs around 90°F (32°C) and lows around 75°F (24°C). This is also the rainy season, so while you’ll still see plenty of sunshine, be prepared for occasional heavy downpours or thunderstorms, often in the late afternoon. Humidity levels are consistently high, usually hovering around 80-90%. You can count on approximately 13 hours of daylight to explore.
What to wear in Tulum in August
Focus on lightweight, breathable fabrics like cotton, linen, and quick-drying synthetics. Loose-fitting clothing is key to staying comfortable in the heat and humidity. While Tulum is generally laid-back, you might want slightly dressier options for evenings out at upscale restaurants. Otherwise, casual beachwear is the norm.
Essentials for Tulum in August
Quick-dry travel towel
Essential for beach days and cenote dips, drying faster than a regular towel in the humid climate and saving space in your bag.
Reef-safe sunscreen
Protect your skin from the intense Caribbean sun while safeguarding Tulum’s delicate coral reefs and marine life.
Biodegradable insect repellent
Mosquitoes can be prevalent, especially after rain and in the evenings; biodegradable options are better for the local ecosystem.
Water shoes or sturdy sandals
Perfect for exploring rocky cenotes, ancient ruins, and uneven paths comfortably and safely.
Lightweight rain jacket or umbrella
Be prepared for sudden tropical downpours that are common during August, ensuring you stay dry during quick showers.
Portable power bank
Keep your phone charged for navigation, photos, and emergencies, especially during long days out exploring.
Wide-brimmed hat
Provides crucial sun protection for your face and neck, preventing sunburn and keeping you cooler.
Small waterproof dry bag
Safeguard your electronics, documents, and valuables from unexpected rain showers or splashes during water activities.
After-sun lotion with aloe vera
Soothe any potential sunburn or skin irritation after a day in the strong tropical sun.
Motion sickness medication
If you plan on boat tours or long car rides, having this on hand can make your travel much more comfortable.
Pro tips
Stay hydrated constantly
The high heat and humidity make dehydration a real risk; always carry a reusable water bottle and refill it frequently.
Book popular tours in advance
August is still a popular time to visit, so secure your spots for sought-after excursions like Sian Ka'an Biosphere tours or specific cenote visits.
Have a backup rain plan
With afternoon showers likely, have a list of indoor activities like cooking classes, spa treatments, or art galleries ready to go.
Frequently asked
Is August a good time to visit Tulum?
While August is part of the rainy season and can be very hot and humid, it's still a fantastic time for those who don't mind embracing the tropical climate. You'll find lush scenery, fewer crowds than peak dry season, and often more affordable prices.
What's the best way to deal with the heat and humidity?
Stay hydrated with plenty of water, wear light and breathable clothing, take frequent dips in the sea or cenotes, and plan your most strenuous activities for the cooler mornings.
How bad are the mosquitoes in August?
Mosquitoes can be quite active, especially around dawn and dusk, and particularly after rain. Pack a good quality biodegradable insect repellent and consider wearing long sleeves and pants in the evenings if you're sensitive to bites.
Should I be worried about hurricanes in August?
August falls within the Atlantic hurricane season (June to November). While the risk is present, direct hits are rare, and modern forecasting provides ample warning. It's wise to consider travel insurance that covers weather-related disruptions.
What kind of footwear is best for exploring?
Comfortable, waterproof sandals or water shoes are ideal for cenotes and beaches. For exploring ruins, sturdy walking sandals or breathable sneakers will serve you well. Avoid anything that will trap heat or take a long time to dry.
Is sargassum (seaweed) an issue in August?
Sargassum levels can be unpredictable and vary greatly from year to year and even day to day. While it can be present in August, local authorities often clean the beaches. Many resorts also work to keep their beachfront clear, and cenotes are always a seaweed-free alternative for swimming.
