Heat index

December's heat index is evaluated at a fiery hot 39°C (102.2°F). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. 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 particular importance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Note: In December, a regular UV index of 7 translates into these guidelines:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
