The best time to visit Aquaventure Waterpark is early morning, close to when the park opens.
Flash your Aquaventure Waterpark tickets, escape the long queues and cover all the top rides at the start of your day, while the lines are still relatively short, and also while it's cooler.
Dubai can get very hot in the middle of the day, especially during summer. There is plenty of shade throughout Aquaventure Waterpark, but be sure to reapply the sunscreen and take regular breaks from the water during this time.
