Weather in December

December marks the onset of the cooler season in Manila with temperatures dipping to around 22.9°C, creating an inviting environment for sightseeing and explorations. It is a time when wind speeds slightly rise, bringing in fresh breezes throughout the city streets. Compared to November, the December climate is cooler, experiences relatively lesser rainfall, and shorter daylight duration. The shift from December's cool weather to January’s slightly warmer climate is a refreshing change for the city’s residents. The year comes to a close with Manila relishing a balanced climate - not too hot, not too cold, and minimal rainfall.

Heat index

The heat index value during December is appraised at a very hot 35°C. Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.
Be aware that heat index ratings are designed for shaded locations and minor breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim. Attention! UV radiation is ramped up when reflecting off sand and water surfaces.
