Heat index

Throughout December, the heat index is estimated at a fiery hot 39°C (102.2°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. 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 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to 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.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
