Weather in September
Temperature
The start of September involves a subtle temperature drop, shifting from a sweltering 96.1°F (35.6°C) in August to a tropical 88.5°F (31.4°C). West reports an average nighttime low-temperature of 70.5°F (21.4°C) in September.Heat index
The heat index value during September is evaluated at a fiery hot 98.6°F (37°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Fend off overexposure. Sun protection is vital. 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. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
