Weather in September
Temperature
The arrival of September is marked by an average high-temperature of a still hot 87.3°F (30.7°C), bearing a close resemblance to August. Vidalia's nighttime temperature during September is consistently averaged at a pleasant 68.2°F (20.1°C).Heat index
Throughout September, the heat index is evaluated at a fiery hot 102.2°F (39°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
