Weather in September
Temperature
Ar Ruff indicates an average high-temperature of a still sweltering 38°C (100.4°F) in September, showing minor variation from August's 35.1°C (95.2°F). Ar Ruff witnesses an average low-temperature of 27.9°C (82.2°F) throughout the month of September.Heat index
September's average heat index is computed to be an extremely hot 43°C (109.4°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.Heat index values are typically calculated for conditions of shade and 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 'feels like' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Also note that objects like parasols or canopies might not provide complete sun protection. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses.
