Records show heat index calculations are tailored for shaded regions and mild winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index estimate of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for average individuals.
Note: The UV index of 7 during May leads to these advisories:
Deter overexposure. Protecting against the sun's effects is essential. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Opt for tightly woven and loose clothing to enhance protection from the Sun.
