When is the best time of year to visit Sharjah? Sharjah has a sub-tropical climate with infrequent rainfall and sunny skies for most of the year. The most pleasant time to visit is during the milder months from November to April, when average daytime highs range from 25°C to 35°C, but nowadays people visit the UAE all year round. It is hot and humid from June to September, with highs of 41-43°C, but summer temperatures are bearable thanks to air conditioning in hotels, restaurants, malls and taxis, and chilled swimming pools to cool off in. With the influence of the mountains, the east coast tends to be cooler during the summer months.
