Weather in December
Temperature
January and December are the warmest months, with an average high-temperature of 28.9°C (84°F).Heat index
During December, the heat index is computed to be a tropical 30°C (86°F). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. 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.
