Weather in December
Temperature
December's average high-temperature stands at a still warm 29.9°C (85.8°F), showing little deviation from November's 27.8°C (82°F). The low-temperature average for Aru during December stands at a refreshing 18.5°C (65.3°F).Heat index
The heat index value during December is evaluated at a tropical 32°C (89.6°F). Continuing activity during long-lasting exposure might induce tiredness and result in heat cramps.Heat index determinations are made taking into account the shade and light air movements. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', quantifies the warmth felt when relative humidity is considered. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. 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.
