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°F (31.1°C). Cason experiences an average low-temperature of 67.1°F (19.5°C) in month of September.Heat index
The heat index value for September is appraised at a very hot 100.4°F (38°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
