Weather in December

Trois-Rivières maintains an average of approximately a still moderately hot 26.2°C (79.2°F) during December nights, with only a minimal decrease from the daytime temperature.Heat index
In December, the heat index is calculated to be a hot 30°C (86°F). If one remains active during constant exposure, it might cause exhaustion and heat cramps.Heat index determinations are made taking into account the shade and light air movements. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
