Weather in December
Temperature
As December unfolds, the average high-temperature reaches a still warm 28.4°C (83.1°F), hinting at a slight fluctuation from the previous month. La Palma, in December, witnesses an average low-temperature of 16.6°C (61.9°F).Heat index
During December, the heat index is evaluated at a tropical 32°C (89.6°F). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', represents the fusion of temperature and moisture in the air to suggest how warm it feels. 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. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. 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.
