Weather in December
Temperature
Stepping into December, Vailala records an average high-temperature of a still moderately hot 28.8°C (83.8°F), almost consistent with November. In December, Vailala's nighttime temperatures demonstrate a slight decrease, stabilizing at an average of 27.9°C (82.2°F).Heat index
December's heat index is estimated at a tropical 33°C (91.4°F). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Heat index determinations are made taking into account the shade and light air movements. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
