Weather in September
Temperature
As September takes its course, Forester's average high-temperature registers at a still hot 86.9°F (30.5°C), closely aligning with the preceding month. The low-temperature average for Forester during September stands at a refreshing 67.1°F (19.5°C).Heat index
Throughout September, the heat index is computed to be a sweltering 98.6°F (37°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
