Weather in September
Temperature
The initiation of September records an average high-temperature of a still hot 88.5°F (31.4°C), displaying a near consistency with the previous month. Nighttime temperatures consistently average a warm 74.3°F (23.5°C) during September.Heat index
September's mean heat index is estimated at an extremely hot 105.8°F (41°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct exposure to the sun's rays can enhance the felt temperature, 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.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Resist extreme sun exposure. Guarding against solar damage is essential. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Boost your sun resistance with garments that are densely woven yet spacious.
