September's weather displays an average high-temperature of a warm 29.3°C (84.7°F), slightly varied from August's 30.2°C (86.4°F). During September, Kouri consistently records a temperature low averaging an agreeable 21.2°C (70.2°F).

Heat index

Throughout September, the heat index is calculated to be a torrid 35°C (95°F). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

UV index

The months with the highest UV index are January through September, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for the ordinary person.
Note: A daily high UV index of 6 in September leads to these guidelines:
Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
