Realize that the values for the heat index are set for shaded places and light winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

In September, the average relative humidity is 83%.

Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
