Weather in December
Temperature
The start of December brings a subtle rise in the average high-temperature, moving from 23.6°C (74.5°F) in November to a still moderately hot 27.4°C (81.3°F). During the month of December, Bernal anticipates a mean low-temperature of 18.5°C (65.3°F).Heat index
During December, the heat index is computed to be 29°C (84.2°F). Fatigue might occur with continuous exposure and activity, potentially causing heat cramps.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
