At the start of September, Fernwood's average high-temperature reaches a still hot 86.9°F (30.5°C), subtly different from the preceding month. Fernwood sees an average low-temperature of 68°F (20°C) during September.Heat index
September's mean heat index is computed to be a fiery hot 102.2°F (39°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Note that heat index values are valued for light wind and location in the shade. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
