Weather in December
Temperature
Entering December, the average high-temperature is recorded at a still tropical 30.5°C (86.9°F), exhibiting a minimal shift from November's 31.3°C (88.3°F). During December, the temperature is averaged to a low of 25°C (77°F) at night.Heat index
The heat index value during December is calculated to be a sweltering 38°C (100.4°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. 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 especially vital to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
