An understanding of weather nuances throughout the year provides a comprehensive understanding of Wewak's dynamic tropical climate.

Temperature

Upon the beginning of December, Wewak's high-temperatures register at a still moderately hot 29.1°C (84.4°F), closely mirroring the preceding month. In Wewak, the December nights are characterized by an average low-temperature of 25.2°C (77.4°F), a minor dip from daytime readings.

Heat index

Throughout December, the heat index is appraised at a very hot 35°C (95°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
Consider that heat index readings are for situations in the shade and light wind. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear. Beware! Reflecting off water and sand, UV rays are much stronger.
