The average high-temperature in December, at a still hot 31.5°C (88.7°F), reveals a modest deviation from November's 32.3°C (90.1°F). An average low-temperature of 24.7°C (76.5°F) marks the month of December.

Heat index

December's average heat index is computed to be a blistering 41°C (105.8°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.
Heat index determinations are made taking into account the shade and light air movements. 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', comes about by integrating the temperature readings with the humidity levels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Keep in mind that shade structures may not provide complete protection. Always opt for UVA and UVB-resistant sunglasses on radiant days. Notice! Sand and water reflections contribute to a stronger UV exposure.
