The weather in Uae won’t surprise you. This is desert territory, after all, and you don’t go there for winter skiing (although you can get some snow skiing in at the indoor ski slope!) or to get away from summer’s heat.
Indeed, you head for Uae knowing full well what awaits you. It’s likely to be hot and sunny. Most Uae experts say it’s best to stay away from the area during the hot summer months, if you can. In the summer, there’s an average of 11 hours of sunshine a day, and all of it is hot.
If you are planning to be in Uae in the summer months – or the hot months of roughly June through September, be prepared for midday temperatures to reach or 42°C to 45°C (108°F to 113°F). On the hottest days the temperatures can reach 48°C (120°F). There’s some respite from the heat at night, when temperatures dip lower, usually in the low 30s C (high 80's to low 90's Fahrenheit) range but then the humidity rises making things quite uncomfortable.
Now, if you are able to go to Uae between December and March, the weather is much more agreeable to most people. During this period, daytime temperatures range between 22°C and 30°C (72°F to 86°F). Nightime minima can get as low as 7°C (45°F) in the city in rare instances but will get lower if you are camping up in the mountains. Depending on where your home is, that might not even seem so cold.
Whatever the outside temperature and whatever time of year, however, you will spend most of your time here in extremely efficient Air con. So you might want to pack at least one warm top.
There is no particular rainy season in Uae, as might be expected, but there can be rainfall at any time, even in the summer; however, January to March has the most rainfall days.
