The favourable time to visit Abu Dhabi is either, during April and May or from September to October. These months, known as the spring and fall shoulder seasons, offer weather, fewer crowds and reasonable hotel rates. If you prefer a milder climate without heat or humidity the winter months from December through March are ideal.
Springtime in Abu Dhabi brings weather with highs ranging from the low 80s to high 90s (Fahrenheit) depending on the month. Hotel rates start to decrease after the peak tourist season ends. Additionally there are festivals and sporting events taking place during this time.
Spending summer in Abu Dhabi can be likened to vacationing in a sauna as temperatures soar into digits while humidity remains high despite rainfall. If you can handle the heat you'll find some deals on accommodations during these months. Hotels regularly reduce their rates by half.
As autumn arrives Abu Dhabi starts to cool down with highs dropping from the 100s in September to the 80s in November. If you're willing to endure the heat you'll likely get a room rate; just keep in mind that hotels may start increasing their prices as the winter high season approaches.
When it comes to weather, winter is the time for a visit to Abu Dhabi. Daytime temperatures are pleasant ranging from mid 70s to 80s – conditions, for exploring the top attractions or enjoying some beach time. However during wintertime there is an influx of tourists and convention attendees so be prepared to pay a higher price for your hotel room.
