The temperatures gradually decline, while the humidity increases. Bedok ends the year on a wet note, grounding in the tropical reality of the region.

Temperature

December reports an average high-temperature of a moderately hot 29.6°C (85.3°F), slightly varied from November's 30.7°C (87.3°F). A modest dip in temperatures to an average of 25.2°C (77.4°F) is observed throughout Bedok's December nights.

Heat index

The heat index in December is estimated at a sweltering 37°C (98.6°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', 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. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
