Heat index

Throughout December, the heat index is calculated to be a very hot 38°C (100.4°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
For clarity, heat index numbers account for light winds and areas under shade. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. 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. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant 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.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

UV index

February through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for the average person.
Note: A maximum high daily UV index of 7 during December translates into the following directions:
Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
