Weather in September
Temperature
Entering September, `Ajlaniyah's average high-temperature reads a still tropical 32.6°C (90.7°F), indicating a close resemblance to the previous month's climate. During September, the nighttime temperature in `Ajlaniyah averages of 26.3°C (79.3°F).Heat index
September's average heat index is appraised at a fiery hot 39°C (102.2°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. 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. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
