In September, the average heat index is appraised at a very hot 98.6°F (37°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent 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. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
