When Does It Actually Rain in the UAE? Month-by-Month Guide 2026

December to March: The Main Rain Window

Most rainfall arrives between December and March. The National Centre of Meteorology records roughly 70-90 mm during these four months across the northern emirates. Coastal cities like Dubai and Abu Dhabi see brief showers, while the Hajar Mountains receive heavier bursts that feed wadis.

Monthly Breakdown for 2026

January remains the wettest month. Expect 25-35 mm on average, mainly from passing frontal systems. February follows with 20-30 mm. March sees a drop to 15-25 mm as temperatures climb. April rainfall falls below 10 mm and becomes rare.

May to September: totals stay under 5 mm. Any showers are short and usually miss urban areas.
October: averages 5-8 mm, mostly over the eastern mountains.
November: rises to 10-15 mm as humidity builds ahead of winter fronts.

Regional Differences Across Emirates

Dubai and Sharjah record slightly higher totals than Abu Dhabi because of their northerly position. Ras Al Khaimah and Fujairah can exceed 120 mm annually due to orographic lift from the Hajar range. Inland Al Ain stays drier at around 70 mm. Western desert areas receive the least, often below 50 mm.

How Authorities Handle Rain Events

RTA activates extra drainage crews on major roads when forecasts exceed 15 mm in 24 hours. DEWA issues public alerts through its app when flash flooding is possible near wadis. ICP and MOHRE do not alter visa or work rules for weather, but schools may close if RTA deems roads unsafe.

Practical Tips for Expats

Keep a light waterproof jacket handy from December to March. Check the RTA app before driving on elevated highways after heavy rain. Homeowners should clear roof drains before the season starts, as insurance policies often exclude water damage from blocked gutters. Tourists should note that beach days remain possible; showers usually last under 30 minutes.
