Heat index

The heat index value during December is computed to be a torrid 35°C (95°F). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes.

Be alert! The reflection of water and sand augments UV radiation intensity.
