Heat index

For July, the heat index is calculated to be a very hot 37°C (98.6°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Note: During July, 7 as the daily maximum UV index converts into the following advice:
Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim. Beware! The reflection of water and sand dramatically increases exposure to the UV rays.
