Weather in September
Temperature
During the shift to September, a minor reduction in average high-temperature is observed, shifting from a tropical 93°F (33.9°C) in August to a still hot 87.6°F (30.9°C). In Chidester, following the steep rise of daytime temperatures, an average nighttime low of 66°F (18.9°C) is anticipated during September.Heat index
September's heat index is appraised at a torrid 100.4°F (38°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
