Weather in December
Temperature
December, recognised by an average high temperature of 27.6°C (81.7°F) and a low of 18.6°C (65.5°F), is Valinhos's warmest month.Heat index
Throughout December, the heat index is evaluated at a hot 31°C (87.8°F). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
