Pro tips

Embrace the Morning Hours

Head out early to enjoy activities before the peak heat and potential afternoon rain. Many tours depart in the morning for this very reason.

Stay Hydrated Constantly

With high temperatures and humidity, dehydration is a real risk. Drink plenty of bottled water throughout the day, even if you don't feel thirsty.

Monitor Hurricane Forecasts

August is peak hurricane season. Keep an eye on weather updates from reliable sources a few days before and during your trip, and know your resort's evacuation plan.

Pack for 'Wet Season' Activities

Consider indoor attractions like museums or shopping malls for rainy afternoons, and embrace water activities for when the sun is out.

Don't Forget About Humidity Management

Bring travel-sized anti-frizz hair products and be aware that clothes may take longer to air dry. Consider packing clothing that doesn't easily wrinkle.
