Weather in September
Temperature
September is characterized by a mild reduction in the average high-temperature, from a sweltering 95.9°F (35.5°C) in August to a tropical 89.4°F (31.9°C). Shepherd sees an average low-temperature of 69.4°F (20.8°C) during September.Heat index
The heat index in September is computed to be a scorching 107.6°F (42°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. 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 are essentially critical for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Resist overexposure. Safeguarding from solar damage is indispensable. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
