UAE Heatwave: Why April Temperatures Are Hitting 40°C Across Emirates

The UAE has recorded temperatures exceeding 40°C in several regions this April, as the country transitions from the spring season toward the peak summer months. National Center of Meteorology (NCM) data confirms that while these spikes are recurring, they signal the onset of the first seasonal heatwaves driven by shifting pressure systems over the Arabian Peninsula. Atmospheric pressure and thermal lows Climatologists attribute the current mercury rise to the extension of thermal lows from the south and east. These systems bring dry, hot air masses from the Arabian Desert, which settle across the UAE’s interior. This phenomenon typically results in a sharp contrast between coastal humidity and the intense heat of inland areas like Al Ain and the Al Dhafra region, where temperatures often peak earliest in the season. Historical data from the NCM indicates that April serves as a bridge between the moderate weather of Q1 and the extreme conditions of Q3. During this month, the influence of the Siberian High recedes, allowing southerly winds to dominate. This shift can cause temporary temperature surges that remain 3°C to 5°C above the 30-year average for short intervals before…
