Dubai: The UAE officially welcomed the summer solstice today, June 21, marking the longest day of the year and the beginning of the country’s most intense weather season. If the heat felt unbearable already, brace yourself — things are about to get even hotter.
Solstice Marks the Peak of Summer
The summer solstice occurred at 6:42 AM UAE time, when the sun reached its highest point in the northern sky. This astronomical event signals the start of peak summer, bringing with it longer daylight hours and rising temperatures across the region.
This happens because the Northern Hemisphere tilts closest to the sun, causing the sun’s rays to shine directly over the Tropic of Cancer (23.37°N) — which passes through the UAE. As a result, temperatures are expected to rise by 2–3°C, pushing highs towards 50°C.
Heat Meets Humidity
While June temperatures typically range from 47 to 49°C, this seasonal shift will push the mercury even higher. Adding to the discomfort, humidity levels — especially along the coast — will make the weather feel even hotter. The “heat index”, or how hot it feels, could exceed 50°C, particularly when moist sea breezes blow inland.
When humidity and temperature both peak, the body’s ability to cool through sweating is reduced, increasing the risk of heat-related illnesses.
Longer Days, Stronger Heat
The solstice also brings longer daylight hours, meaning more solar radiation and more time for concrete, roads, and buildings to absorb heat — a phenomenon known as the urban heat island effect. This causes cities to remain sweltering even after sunset.
Where to Cool Off: UAE’s Natural Escapes
If the city heat becomes too much, there are a few cooler spots worth exploring:
- Jebel Jais, Ras Al Khaimah
UAE’s highest peak offers a 10–15°C drop in temperature compared to major cities. Daytime temps hover around 31°C, dipping to 27°C in the evening. - Jebel Hafeet, Al Ain
Consistently cooler due to elevation, this mountain is ideal for sunset views and short drives, staying mostly below 40°C even in July and August. - Al Hajar Mountains
Stretching from Ras Al Khaimah to Fujairah, these scenic mountains offer early morning hikes and cooler microclimates, especially in the higher elevations. - Mountain Wadis (Valleys)
Shaded and scenic, the wadis in eastern UAE provide a refreshing escape for explorers and photographers alike. - Eastern Coast (Fujairah)
While still hot, the eastern coast often enjoys sea breezes and cloud cover, offering occasional relief from the inland heat.
Take Precautions
Authorities continue to advise caution during this period. Avoid outdoor activities during peak heat hours (typically 12pm to 4pm), stay hydrated, and monitor weather alerts. As temperatures continue to climb, personal safety remains the top priority.
