Weather in December
Temperature
The month of December, characterized by an average high of 30.7°C (87.3°F) and a low of 23°C (73.4°F), is recognized as the coldest.Heat index
For most parts of December, the heat index is computed to be a blisteringly hot 42°C (107.6°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Heat index readings emphasize conditions of light breezes and shaded spots. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
