September in
Aden,
Yemen, arrives with a break from the incessant high temperatures, recording a dip to 35.4°C (95.7°F). A perceptible wane in sunlight hours indicates the approach of the cooler months ahead. However, September doesn’t exhibit a drastic change in sea temperatures or humidity, resulting in an enjoyable month, ideal for sightseeing. With rainfall occurrences matching
August figures, the likelihood of dry weather remains high, making it suitable for outdoor ventures.
Temperature
Aden's weather in September displays an average high-temperature of a still sweltering 35.4°C (95.7°F), showing minor disparity from August's 35.3°C (95.5°F). During September, Aden sees a mean low-temperature of 27.8°C (82°F).
Heat index
September's average heat index is estimated at a life-threatening hot 51°C (123.8°F).
Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
Humidity
The average relative humidity in September is 69%.
Rainfall

UV index
February through September, with an average maximum UV index of 12, are months with the highest UV index in Aden. A UV Index value of 11, and more, symbolizes an excessive health risk from unsafe exposure to UV radiation for average individuals.
Note: A daily maximum UV index of 12 in September translates into the following instructions:
Implement every essential safety step. Individuals with fair skin might receive burns in less than 5 minutes. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat. Apply liberally and reapply a broad-spectrum sunscreen of SPF 30+ every two hours, and promptly after any outdoor workout or a swim. Be mindful! Sand and water reflections can up the Sun's UV exposure.
