The onset of December notes an average high-temperature of a still moderately hot 28.9°C (84°F), subtly shifted from November's 28.8°C (83.8°F). Throughout the month of December, the nighttime temperature dips to an average of 20.7°C (69.3°F).

Heat index

During December, the heat index is computed to be a sweltering 36°C (96.8°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
