Heat index

The heat index value during December is calculated to be a scorching 41°C (105.8°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

In December, the average relative humidity is 80%.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
