Temperature

The arrival of December denotes a barely perceptible change in the average high-temperatures to a still tropical 31.7°C (89.1°F) from November's 31.4°C (88.5°F). Nighttime temperatures hover around an average low of 22.4°C (72.3°F) in December.

Heat index

The average heat index in December is computed to be a blisteringly hot 41°C (105.8°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for 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.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Humidity

The average relative humidity in December is 75%.
