Weather in December
Temperature
The commencement of December introduces an average high-temperature of a still tropical 30.5°C (86.9°F), closely mirroring the preceding month. An average minimum temperature of 20.3°C (68.5°F) is recorded during the month of December.Heat index
During December, the heat index is calculated to be a very hot 35°C (95°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
