United Arab Emirates in May: Weather, Crowds & What to Expect

Dubai & the Northern Coast (Dubai, Sharjah, Ajman)

Humidity measurably climbs in May and the city feels hotter - daytime highs frequently reach 36-40°C and coastal humidity makes the heat feel heavier. Beaches are still popular at dawn and dusk, but mid-day should be reserved for indoor malls, museums and air‑conditioned attractions. Travelers should be prepared for strong sun, pack lightweight breathable clothing, and expect many hotels and restaurants to operate at full capacity despite the heat.

Abu Dhabi & the Western Coast (Abu Dhabi city, Al Dhafra, Yas, Saadiyat)

Full summer heat arrives in May with daytime readings often 38-42°C along the coast and higher inland; humidity increases, making long outdoor periods uncomfortable. Water-based activities on Saadiyat and Yas are still popular at dawn and dusk, but midday should be reserved for air-conditioned venues. If traveling for budget reasons, some hotels run summer promotions while key outdoor experiences operate with heat-focused schedules.

Hajar Mountains & Northern Highlands (Ras Al Khaimah, Jebel Jais, Jabal Hafeet approaches)

May brings substantially warmer days below the summits while the mountains still provide noticeable relief from coastal humidity; daytime highs in the canyons can reach the low 30s°C. The higher road to Jebel Jais is increasingly popular at dawn for sunrise trips; bring water and sun protection for exposed sections. Rock-climbing and canyoning operators start shifting schedules to early morning to avoid the strongest heat in the late afternoon.

Fujairah & the East Coast (Fujairah city, Khor Fakkan, Dibba)

Warm, pleasant days in May make Fujairah a popular shoulder-season destination: daytime temperatures are generally in the low-to-mid 30s°C but the breeze from the Gulf of Oman keeps humidity more bearable. Snorkeling and scuba trips operate regularly and the coastline’s cliffs are great for short hikes. Expect fewer crowds than Dubai and lower accommodation prices than the winter high season, but book popular dive trips in advance for weekends.

Rub’ al Khali & Desert Interior (Liwa, Empty Quarter approaches)

By May the Empty Quarter becomes extreme: daytime temperatures often exceed 40°C and the sun is severe, making strenuous daytime activity unsafe without careful planning. Most desert tours operate at dawn or dusk and many guests choose to shelter in air-conditioned camps during the hottest hours. If you must travel overland, ensure vehicles are well‑prepared with extra fuel, water and communication equipment.
