December weather forecast
Mangga, Philippines

The first month of the winter, December, is still a warm month in Mangga, Philippines, with an average temperature ranging between min 24.3°C (75.7°F) and max 29.5°C (85.1°F).

Temperature

December's presence marks an average high-temperature of a moderately hot 29.5°C (85.1°F), subtly varied from November's 30.5°C (86.9°F). In the month of December, the average temperature dips to 24.3°C (75.7°F) during the night.

Heat index

Throughout December, the heat index is evaluated at a torrid 35°C (95°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', quantifies the warmth felt when relative humidity is considered. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception 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 77%.

Note: A daily maximum UV index of 7 in December translates into the following instructions:
Deter overexposure. Protecting against the sun's effects is essential. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
