Weather in December
Temperature
The average high-temperature during December is a tropical 33.6°C (92.5°F), almost matching the conditions of the preceding month. In the month of December, the average temperature dips to a warm 23.7°C (74.7°F) during the night.Heat index
The heat index in December is calculated to be a blistering 40°C (104°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. 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 are extremely significant 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.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Deflect overexposure. Sun protection is a necessity. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
