Weather in December
Temperature
The onset of December marks a slight increase in the average high-temperature, moving from 23.6°C (74.5°F) in November to a still moderately hot 27.3°C (81.1°F). Olivos, during the nights of December, experiences an average temperature drop to a comfortable 18.9°C (66°F).Heat index
December's average heat index is evaluated at 29°C (84.2°F). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
