The most demanding months are July, August and September, when, in addition to extremely high temperatures, there is also high humidity, making the climate very difficult to bear. This is the ideal time only for people who really like real heat and want to enjoy almost tropical conditions, because the water in the Persian Gulf remains exceptionally warm at that time – often resembling the temperature of a hot bath. When to swim in Dubai? Basically, any time of the year – the weather and water in Dubai are ideal for swimming from January to December.

For active travellers, the best months are from October to May, when, in addition to swimming in the sea, you can freely enjoy water sports such as diving and paddleboarding.
