We find every place where you can swim and show you the water temperature there today and throughout the year.
Current Water Temperature
The water temperature in the Persian Gulf today ranges from 21.8°C (Al Khafji, Saudi Arabia) to 25.3°C (Pasabandar, Iran).
As of today, the minimum water temperature in the Persian Gulf ranges from 68°F (20°C) to 74°F (23°C). The water is warm and pleasant for swimming, and in this range, one can stay in the water for extended periods without the risk of hypothermia. This is the ideal temperature for relaxation, swimming, and water sports. Families with children, as well as outdoor enthusiasts, will enjoy swimming and time spent in the water. For most people, this is the optimal temperature for a comfortable beach experience.
It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

The Persian Gulf is a shallow, semi-enclosed body of water whose limited depth and high solar radiation produce warm sea surface temperatures year-round. Seasonal averages typically run from about 15–22 °C in winter (December–February), rising to roughly 20–28 °C in spring (March–May). Summer (June–August) is the hottest period, with coastal waters commonly between 28–36 °C and occasional local readings above 36 °C in very shallow bays. Autumn (September–November) sees temperatures moderate again to about 25–31 °C. There is regional variation: areas closer to the Strait of Hormuz and deeper channels tend to be a few degrees cooler than shallow northern embayments and coastal lagoons, which warm more quickly.
Swimming Conditions
Swimming in the Persian Gulf is widely permitted and popular, particularly at resort beaches and managed public shores, because water temperatures are generally within comfortable ranges for bathing for much of the year. The most pleasant times for recreational swimming are spring, autumn, and the milder parts of winter; summer swimming is possible but can be physically taxing because of very high water and air temperatures, which increase heat stress and reduce comfort. Local water quality, occasional algal blooms or jellyfish, coastal construction and pollution can restrict access in some places, and authorities may close beaches when safety is a concern. Visitors are advised to follow local advisories, respect signage and lifeguards, and consider regional seasonal conditions when planning to swim.
