Heat index

The heat index value for August is appraised at a life-threatening hot 47°C (116.6°F). Remain cautious: Heat cramps along with heat exhaustion are foreseeable. Ongoing activity may precipitate heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Heads up! UV intensity is amplified by reflections from water and sand.
