Weather in December

December's heat index is appraised at a fiery hot 38°C (100.4°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital 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.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
