Heat index

The heat index value for December is evaluated at a blazing hot 45°C (113°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.
Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
