December welcomes an average high-temperature of a still moderately hot 27.2°C (81°F), not much different from the preceding month. An average nighttime temperature of 18.4°C (65.1°F) is noted in Cerrito during the month of December.Heat index
The heat index value during December is computed to be 29°C (84.2°F). Constant activity during exposure could result in a state of weariness and possibly heat cramps.Consider that heat index readings are for situations in the shade and light wind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. 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 are highly important for children. 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.
