Weather in September
Temperature
Start of September brings a slight shift in the average high-temperature, dipping a bit from August's very hot 95°F (35°C) to a tropical 88.9°F (31.6°C). Hall Summit's average low-temperature is measured at an enjoyable 67.8°F (19.9°C) during September.Heat index
September's average heat index is appraised at a blistering 104°F (40°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Understand that the heat index values take into account shaded locations and mild winds. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.
