Weather in December
Temperature
Cambridge transitions into December recording an average high-temperature of a still moderately hot 27.5°C (81.5°F), closely aligning with the preceding month's temperature. Cambridge indicates a consistently low-temperature of 24.9°C (76.8°F) during the nights of December.Heat index
In December, the average heat index is computed to be a hot 31°C (87.8°F). With unrelenting exposure and activity, one might experience exhaustion, leading to potential heat cramps.Heat index readings emphasize conditions of light breezes and shaded spots. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
