Heat index

In September, the heat index is appraised at a very hot 98.6°F (37°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially crucial for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
