December weather forecast
Sorong, Indonesia

Concluding the year, the weather in December continues the momentum set by November's conditions. Despite holding the year’s peak rainfall of 186mm (7.32"), December’s weather plays a pivotal role in maintaining Sorong's monsoon climate. Its consistent temperatures draw a balmy end to the year - a signature of Sorong's year-round tropical feel. To wrap up, December’s weather can be described as a balanced mix of warmth, moisture, and sunlight.

Temperature

Sorong starts December with an average high-temperature of a still tropical 30.4°C (86.7°F), hinting at a minimal fluctuation from November. The temperature dips to an average of 25.3°C (77.5°F) during December nights.

Heat index

The heat index in December is calculated to be a very hot 39°C (102.2°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Rising body temperatures due to excess heat retention could signify impending heat disorders.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
