Weather in December
Temperature
Entering December, the average high-temperature is recorded at a still hot 31°C (87.8°F), exhibiting a minimal shift from November's 30.1°C (86.2°F). The average low-temperature, in December, is a moderately hot 24.5°C (76.1°F).Heat index
The heat index value during December is calculated to be a very hot 37°C (98.6°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
