Weather in September
Temperature
September is characterized by a slight reduction in average high-temperature, easing from a sweltering 95.5°F (35.3°C) in August to a hot 86.9°F (30.5°C). Nightly temperatures in Sanctuary, Texas, drop to an average low of 68.5°F (20.3°C) in September.Heat index
The average heat index in September is appraised at a sweltering 95°F (35°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
