Heat index determinations are made taking into account the shade and light air movements. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

July through September, with an average relative humidity of 79%, are the most humid months.

Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
