Weather in September
Temperature
The move into September indicates a slight reduction in the average high-temperature, down from August's sweltering 98.2°F (36.8°C) to a tropical 92.5°F (33.6°C). An average nighttime temperature of 77.2°F (25.1°C) is noted during the month of September.Heat index
In September, the average heat index is calculated to be a blisteringly hot 109.4°F (43°C). Prudent: Heat cramps and heat exhaustion are likely. Heatstroke becomes imminent with sustained exertion.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
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. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection.
