Weather in December
Temperature
December's advent presents an average high-temperature of a still hot 30.4°C (86.7°F), indicating a slight variation from the conditions of the previous month. Prepedan registers a subtle dip to an average of 26.6°C (79.9°F) during the nights of December.Heat index
Throughout December, the heat index is computed to be a torrid 37°C (98.6°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Understand that the heat index values take into account shaded locations and mild winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for the average person.Note: A daily high UV index of 7 in December leads to these guidelines:
Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
