Heat index

In July, the average heat index is computed to be a very hot 39°C (102.2°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. 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 are primarily vital for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Note: A maximum high UV index of 11 in July translates into the following recommendations:
Carry out every crucial safety measure. People with fair skin may sustain burns in fewer than 5 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Following every swim or outdoor workout, a sunscreen with an SPF of not less than 30 should be liberally applied and re-applied frequently, even on overcast days.
