Heat index

The heat index value for December is computed to be a sweltering 37°C (98.6°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
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. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Humidity

In December, the average relative humidity is 76%.

Inhibit overexposure. Warding off sun damage is of utmost importance. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
