Weather Abu Dhabi
Abu Dhabi is the capital of the United Arab Emirates and the second largest city in the U.A.E. behind Dubai. The U.A.E. makes up a small portion of the Arabian Peninsula and shares its southwestern border with Saudi Arabia. Abu Dhabi is actually an island in northern U.A.E., in the southern end of the Persian Gulf, and is joined to the mainland by a few bridges. There are many other small islands surrounding Abu Dhabi.
Abu Dhabi has a very hot desert climate surrounded by sand and water. There are some mountains a distance from Abu Dhabi but they don't generally influence Abu Dhabi's climate. Abu Dhabi is just a little hotter and drier than Riyadh, which lies at roughly the same latitude.
Abu Dhabi's annual averages don't fluctuate much between hot and cold, really just between hot and hotter. Rain is rare. Because of these factors Abu Dhabi's seasons are only split between the hot season and the cooler season.
The hot season in Abu Dhabi generally ranges from April to October. Rain is rare, and temperatures and humidity can be unbearable for many people. The cooler season from November to March has milder temperatures and more comfortable humidity levels. Rain during this time is still only between 10-20mm each month.
The best time to visit Abu Dhabi depends on if you're looking for cheap prices or comfortable temperatures. The shoulder seasons of April-May and September-October have the cheapest flights and hotels but they're hotter and more humid.
The middle of the cooler season December through February has much more comfortable weather for most people.

Extreme Weather
Sandstorms aren't the apocalyptic storms that Hollywood makes them out to be, but they do still occur in the summer. They're not disastrous but they can reduce visibility and lightly coat everything with sand.
Average temperatures have also been on the rise in recent years. Locals have done well to acclimatize to the hot weather, as they've done for thousands of years. It's a source of pride for them, but can be dangerous for tourists not used to it. Use caution when exerting yourself outdoors.
