Weather in September
Temperature
September and October represent the warmest period, with an average high-temperature of 33.6°C (92.5°F).Heat index
For most parts of September, the heat index is evaluated at a blisteringly hot 43°C (109.4°F). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.Note that heat index values are valued for light wind and location in the shade. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

February through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high threat to health from unprotected exposure to Sun's UV rays for average individuals.Note: In September, a daily maximum UV index of 7 leads to the following instructions:
Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. 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. Tightly woven clothing, when worn loosely, shields effectively against the Sun. Take caution! The UV rays from the Sun gain strength from sand and water reflections.
