Weather in September
Temperature
The advent of September brings a subtle shift in temperature, with the average high moving from a hot 94.6°F (34.8°C) in August to a still tropical 88.9°F (31.6°C). Throughout the month of September, Browndell reports a steady low-temperature average of 68.7°F (20.4°C).Heat index
The heat index in September is computed to be an extremely hot 105.8°F (41°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

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. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim. Be watchful! The reflection of snow can enhance the intensity of the Sun's UV radiation nearly double.
