Weather in September
Temperature
September is marked by an average high-temperature of a still tropical 32.6°C (90.7°F), almost identical to the preceding month. September introduces a small decrease to a nighttime average of 29.9°C (85.8°F) in Ad Dirjaj.Heat index
For September, the heat index is evaluated at a blistering 42°C (107.6°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Know that the heat index computations account for shaded terrains and slight winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

It is essential to prioritize protection. Unprotected skin and eyes can suffer rapid harm. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
