Weather in September
Temperature
With the onset of September, the average high-temperature stands at a still hot 33.5°C (92.3°F), closely aligned with August's 31.8°C (89.2°F). In Ouayalgui, September is marked by an average low-temperature of 24.2°C (75.6°F).Heat index
The heat index for September is estimated at a blistering 43°C (109.4°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly 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.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Always remain cautious. Unprotected skin and eyes are prone to swift harm. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
