Weather in December
Temperature
The beginning of December reveals an average high-temperature of a still tropical 30.5°C (86.9°F), showing minimal deviation from the previous month. Nighttime temperature reflects an average dip to a warm 25.7°C (78.3°F) in December, subtly cooler than its daytime highs.Heat index
The heat index in December is estimated at a fiery hot 37°C (98.6°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Note that heat index values are valued for light wind and location in the shade. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for 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.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
