Heat index

The average heat index in December is estimated at a torrid 38°C (100.4°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Resist overexposure. Safeguarding from solar damage is indispensable.

A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
