Weather in December
Temperature
As November transitions into December, a subtle temperature shift is observed, with average highs adjusting from 25.8°C (78.4°F) to a still warm 29.5°C (85.1°F). In Matheu, the December nights descend to a significantly cooler average of 17.4°C (63.3°F) compared to daytime highs.Heat index
Throughout December, the heat index is estimated at a tropical 32°C (89.6°F). Unrelenting activity during exposure could cause fatigue and potentially lead to heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
