Weather in September
Temperature
As Forester welcomes September, the average high-temperature records at a still tropical 86.9°F (30.5°C), marking an insignificant deviation from the prior month. The mean low-temperature during September nights is a comfortable 67.1°F (19.5°C).Heat index
September's average heat index is evaluated at a sweltering 98.6°F (37°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. 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 are particularly relevant to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
