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

Upon the onset of December, Sorong witnesses an average high-temperature of a still hot 30.4°C (86.7°F), showing a close resemblance to the prior month. In Sorong, December is marked by an average low-temperature of 25.3°C (77.5°F).

Heat index

The heat index value for December is estimated at a torrid 39°C (102.2°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. Caution! The Sun's UV rays become stronger due to reflections from water and sand.
