Weather in December
Temperature
The average high-temperature for December is a still tropical 31.2°C (88.2°F), closely aligning with the temperature of the preceding month. An average nighttime temperature of 23.2°C (73.8°F) is recorded during December.Heat index
The heat index in December is computed to be a torrid 39°C (102.2°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
