Dubai’s arid subtropical climate makes for perennially good weather and sunshine all year round, but for newly arrived expats, the heat in summer might be a real shock. Visitors and residents alike should take adequate precautions against heat stroke and exhaustion, and always keep properly hydrated.
The hottest months in Dubai are between June and September, when temperatures can reach a sweltering 113°F (45°C) and the humidity becomes stifling, especially in the coastal regions. Even the sea temperature touches on 104°F (40°C) during the summer months, and swimming pools at hotels are usually cooled to be more 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.
