From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense. Be on guard! The reflective nature of sand and water boosts UV exposure.
