Heat index

In December, the average heat index is evaluated at an extremely hot 42°C (107.6°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Note: In December, a regular UV index of 7 translates into these guidelines:
Guard oneself from overexposure. Defence against sun injury is vital. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. Beware! The reflection of water and sand dramatically increases exposure to the UV rays.
