May weather forecast
Aden, Yemen

May, embarking on the summer season, singles itself out with hot temperatures peaking at an impressive 34.1°C (93.4°F). However, the higher temperature does not reflect into increased rainfall, remaining minimized. Greater daylight and the warm sea make for a perfect premise for water-based activities. Sunglasses and sunscreen become essentials, given the extended hours of sunshine. In terms of relative humidity, the increase becomes less conspicuous, leading to comfortable, though noticeably warmer, outdoor experiences.

Temperature

Aden experiences a subtle adjustment in high-temperatures to a still hot 34.1°C (93.4°F) with the onset of May, maintaining near parity with April's 32.2°C (90°F). During May, the average low-temperature is a warm 27.7°C (81.9°F).

Heat index

The average heat index in May is calculated to be a blazing hot 48°C (118.4°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Note: In May, a daily maximum UV index of 12 leads to the following instructions:
Take every essential safety procedure. Individuals with fair skin could sustain burns in less than 5 minutes. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation. A sunscreen boasting a minimum SPF of 30 should be generously applied and reapplied even on cloudy days, post swim or outdoor exercise. Caution! The Sun's UV intensity grows with reflections off sand and water.
