Heat index

For most parts of December, the heat index is estimated at a torrid 39°C (102.2°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Humidity

The average relative humidity in December is 63%.

UV index

January through December, with an average maximum UV index of 7, are months with the highest UV index. January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index of 6 to 7 symbolizes a high health hazard from unprotected exposure to Sun's UV rays for average individuals.
Note: An average UV index of 7 in December transforms into this advice:
Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
