The start of December sees the average high-temperature at a still hot 31°C (87.8°F), showing little difference from November's 30.1°C (86.2°F). Throughout the month of December, Lumley reports a steady low-temperature average of 24.5°C (76.1°F).

Heat index

The heat index value for December is appraised at a very hot 37°C (98.6°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
Heat index data is primarily for areas with shade and subjected to light winds. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Note: In December, the maximum UV index of 7 suggests these recommendations:
Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
