If you have to decide when to go to Abu Dhabi, consider that the climate is arid and sub-tropical, the sun shines almost all year round and rainfall is rare.
The period usually recommended to visit Abu Dhabi is between the end of October and the first half of May.
If you are looking for seaside holidays in Abu Dhabi, the best periods are generally between late October and December, although November may be at risk of jellyfish. Also the “mid-season”, between the end of March and April, can be fine to visit Abu Dhabi, depending on the year.
Apart from the hottest period, from June to September, or when the wind is strong, virtually all year you can stay on the beach. Anyway, consider that almost all the four and five star hotels have a swimming pool, equipped with umbrellas and deckchairs, often outdoors.
In November, the climate of Abu Dhabi is very mild and the sky is blue: this month’s nightlife takes place outdoors with sporting and cultural events that take place on the beach. November is the month of the Abu Dhabi Formula 1 Grand Prix also and, not because am Italian, I can assure that it’s a very exciting event.
December 2nd is the Emirates National Day and in Abu Dhabi it is celebrated with various and involving events.
From June to September, in Abu Dhabi temperatures reach the peak and the mercury marks often 40 degrees or more, with a high humidity percentage. In this period tend to occur more frequently sandstorms. As a result of sand and humidity, the sky is often “blurred”.
In planning your trip to Abu Dhabi, consider also that the Holy Month of Ramadan is on dates changing every year: in public places, tourists and non-Muslims expats also are required to be respectful and to follow the “etiquette” rules.
