Heat index

December's mean heat index is estimated at a torrid 39°C (102.2°F). Emphasize additional safety, risk of heat cramps and heat exhaustion is high. Continuous activity might result in heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Refrain from overexposure. Fair-skinned individuals could burn in under 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. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
