Weather in September
Temperature
Mayhew marks the arrival of September with an average high-temperature of a still hot 86.7°F (30.4°C), hardly different from August's 91°F (32.8°C). In Mayhew, in September, the average low-temperature is an enjoyable 66.2°F (19°C).Heat index
For most parts of September, the heat index is evaluated at a very hot 96.8°F (36°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
