Heat index

Throughout December, the heat index is estimated at a very hot 39°C (102.2°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
