TL;DR

In July, Dubai’s sea can feel extremely warm, with reported water temperatures around 36–37°C and heat feeling like 44°C because of humidity. The beach is often not refreshing at all, so travelers rely more on cold bottled water and air-conditioned indoor breaks.

What the community said

One recent report gives a contrasting experience: the sea felt refreshing thanks to cold underwater currents, making it hard to leave the water, and the weather was also great — suggesting conditions can vary a lot by day and beach.

A recent report says that by around 4:30 pm in Dubai, the sea was about 36°C while the air was also around 36°C. It felt more like stepping into a hot bath than the sea, so the beach did not provide real cooling.

Another recent traveler said the sea was around 37°C. Even visitors used to very hot climates found the coastal humidity exhausting, and said the only real relief came from cold bottled water from supermarkets, not from swimming.

An earlier report described Dubai’s summer sea as bath-like, with air temperatures around 40–42°C and a heat index closer to 44°C because of humidity. Jellyfish were said to be absent in such hot water, but the sea itself was too warm for comfortable swimming.
