Weather in December
Temperature
The arrival of December marks a slight shift to an average high-temperature of a still tropical 30.8°C (87.4°F) from November's 31.9°C (89.4°F). Rappang notes an average temperature descent to a moderately hot 26.1°C (79°F) in December, a small shift from its daytime peak.Heat index
For most parts of December, the heat index is calculated to be a torrid 38°C (100.4°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.It is important to note that the heat index values are for shaded areas and light wind scenarios. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Deter overexposure. Protecting against the sun's effects is essential. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses.
