Weather in December
Temperature
The shift from November to December is characterized by an average high-temperature of a still moderately hot 28.2°C (82.8°F), not significantly different from the 26°C (78.8°F) of November. Despite the drastic temperature difference, Dordrecht records an average nighttime low of 14.7°C (58.5°F) throughout December.Heat index
For December, the heat index is appraised at 28°C (82.4°F). Long-standing exposure and activity could induce a feeling of tiredness and lead to heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
