Temperature

The shift into December brings a slight increase in the average high-temperature, moving from a warm 28.1°C (82.6°F) in November to a tropical 31.5°C (88.7°F). The temperature notes a substantial fall from the daily peak to an average of 16.7°C (62.1°F) during December nights.

Heat index

In December, the average heat index is estimated at a very hot 36°C (96.8°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

The average relative humidity in December is 59%.

Note: A maximum high UV index of 6 in December translates into the following recommendations:
Ward off overexposure. Defence against solar harm is crucial. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
