Dubai enjoys an arid subtropical climate, with blue skies and sunshine all year round. The hottest months are between June and September, when temperatures can soar to 113°F (45°C) and more during the day and humidity levels are very high. Even the sea temperature touches on 104°F (40°C) during the summer months, and swimming pools at hotels are usually cooled to be refreshing. Temperatures are only slightly more moderate the rest of the year, the coolest time being between December and March with temperatures between 57°F (14°C) and 77°F (25°C). There is very little rainfall in Dubai, but when showers do fall it is mainly in the cooler months.
