The shift from November to December is characterized by an average high-temperature of a still hot 31.2°C (88.2°F), not significantly different from the 33.3°C (91.9°F) of November. During the nights in December, an average low-temperature of 21.2°C (70.2°F) is observed.

Heat index

In December, the heat index is calculated to be a fiery hot 35°C (95°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Heat index readings emphasize conditions of light breezes and shaded spots. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
