Heat index

For most parts of June, the heat index is computed to be a sweltering 38°C (100.4°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Note: The daily high UV index of 12 in June translates into this advice:
Ensure every crucial precaution is taken. Individuals with light skin could experience burns in under 5 minutes. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days. Even on a cloudy day, sunscreen with a minimum SPF of 30 should be used liberally and reapplied often, especially after a swim or outdoor activity. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
