Weather in December
Temperature
The commencement of December notes an average high-temperature of a still hot 31.7°C (89.1°F), exhibiting little difference from the previous month. During December, Cardeal da Silva experiences an average low-temperature of 21.3°C (70.3°F) at night.Heat index
The average heat index in December is evaluated at a blistering 41°C (105.8°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
