Heat index

December's heat index is evaluated at a blistering 41°C (105.8°F). Emphasize additional safety, risk of heat cramps and heat exhaustion is high. Continuous activity might result in heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Note: An average UV index of 7 in December transforms into this advice:
Fend off overexposure. Sun protection is vital. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
