Is it comfortable to use the beach or pool in Dubai in summer, and how warm is the sea?

In early July, daytime air reaches 38°C and nighttime stays around 29°C, while the sea is described as like warm milk — very warm and not refreshing.

For cooler swimming conditions, locals suggest swimming in the morning between 5:30 and 10:00 AM; by evening after 5 PM the water has warmed up significantly from the day's heat.

On Palm Jumeirah in early July, conditions can change a lot from one day to the next: after a very hot and humid day, the next one may feel around 3°C cooler with some breeze. Overall it is still manageable, and the pool area usually feels more comfortable than the beachfront.

For daytime relaxation, the pool is usually better than the sea: with an umbrella, SPF 50 sunscreen, regular dips in the pool, and enough drinking water, you can stay there most of the day. The beach feels much hotter because the sea no longer cools you off.

By late June in Dubai, the sea in the evening can be nearly as warm as the air. That means you may barely notice any temperature change when getting out of the water, so the sea does not provide the usual cooling effect.

In early July, sea temperature can be around 33°C. That is why the beach feels hotter than the pool area: the water is already very warm and does not cool you down much, even when swimming.
