Weather in December
Temperature
December's advent denotes a minor fluctuation in the average high-temperature to a still hot 30.6°C (87.1°F) from November's 30.3°C (86.5°F). The anticipated average low-temperature for December, a refreshing 17.8°C (64°F), shows a substantial deviation from the daytime maximums.Heat index
The heat index value for December is computed to be a fiery hot 36°C (96.8°F). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.For clarity, heat index numbers account for light winds and areas under shade. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. 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 quite important for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
