Temperature

December's beginning signals an average high-temperature of a still tropical 31.5°C (88.7°F), barely different from November's 30°C (86°F). During December, the average low-temperature is an agreeable 22.3°C (72.1°F).

Heat index

December's average heat index is estimated at a scorching 40°C (104°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
Consider that heat index readings are for situations in the shade and light wind. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
