The United Arab Emirates is currently experiencing a significant escalation in heat and humidity, a period traditionally linked to the rising of the Suhail star, often referred to as "Suhail's Ailments." This intense weather phenomenon is expected to persist until the autumnal equinox on September 23rd.
Forecasters indicate that the oppressive combination of soaring temperatures and elevated humidity levels will continue. Inland areas have consistently recorded daily highs exceeding 50 degrees Celsius throughout June and July, with a notable reading of 51.8°C in Sweihan, Al Ain, on August 1, 2025. This marks the highest temperature recorded in nine years for August, surpassing the previous record set in 2017. Sweihan, known for its desert geography and low elevation, frequently experiences extreme heat, having recorded similar temperatures in July 2021 and nearing Al Ain's all-time record of 52.1°C from July 2002.
The National Centre of Meteorology (NCM) has issued warnings, including a Yellow Dust Alert, due to hot, dry winds that can reduce visibility. Coastal cities like Dubai and Abu Dhabi have endured temperatures in the mid-40s Celsius, with humidity exacerbating the heat's effects. The NCM has advised residents to stay hydrated, limit outdoor exposure during peak hours, and protect vulnerable populations.
Culturally, the appearance of the Suhail star, also known as Canopus, around August 24th, traditionally heralds the end of the most intense summer heat. While the star's visibility does not directly alter weather patterns, its arrival coincides with the seasonal transition, often leading to a gradual decrease in temperatures and humidity. This period, known as the "Suhail Season," is eagerly anticipated by residents seeking relief from the sweltering conditions.
Historically, Bedouin tribes, sailors, and pearl divers closely monitored the Suhail star to adjust their activities. The transition period, locally termed Sufriya, lasts approximately 40 days, bridging the peak of summer with milder autumn conditions. During Sufriya, daytime temperatures may remain in the 40–43°C range, but nighttime temperatures gradually decline, offering more comfortable sleep and making early mornings and late evenings more amenable to outdoor activities.
High humidity levels, particularly in coastal areas where it can reach up to 100%, intensify the sensation of heat and impede the body's natural cooling mechanisms. This combination of heat and humidity can lead to heat-related illnesses, including heat exhaustion and heatstroke, and can also trigger skin irritations and respiratory issues. Authorities consistently advise residents to take precautions to mitigate these health risks.
