Weather in December
Temperature
March and December are identified as the warmest months, with an average high-temperature of 33.8°C (92.8°F).Heat index
During December, the heat index is appraised at a blisteringly hot 42°C (107.6°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
