Weather in September
Temperature
With the onset of September, Britton's climate undergoes a slight change as the average high-temperature moves from a very hot 95.5°F (35.3°C) in August to a hot 87.4°F (30.8°C). During the month of September, an average temperature of 69.4°F (20.8°C) is noted during the nights.Heat index
The heat index for September is estimated at a very hot 95°F (35°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. 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. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
