Weather in September
Temperature
September's onset introduces a mild reduction in the average high-temperature, from a sweltering 95.5°F (35.3°C) in August to a tropical 88.7°F (31.5°C). Throughout September, the average low-temperature in Snook, Texas, records at an agreeable 70.5°F (21.4°C).Heat index
The average heat index in September is appraised at an extremely hot 104°F (40°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. 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', gives an indication of how one might feel in terms of heat after considering humidity. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. 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 extremely vital to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
