August weather forecast
Wewak, Papua New Guinea

Moving into the heart of the tropical winter, August in Wewak is distinguished by lower rainfall levels, relative to the showers that grace July. Embracing the continuity in the transformation of the climatic conditions, August synergizes with the ongoing monsoon currents. Across the pristine beaches of Wewak, the temperature of the sea drops delicately to 28.7°C (83.7°F), the coldest for the year. Even though the weather remains primarily consistent, discernible changes are notable in the sea temperature. With the coming of September, the weather pattern marks another phase in its cycle.

Temperature

With August's arrival, Wewak notes an average high-temperature of a still warm 29.3°C (84.7°F), closely following the trend of the preceding month. Wewak experiences an average nighttime temperature of 24.8°C (76.6°F) in August, reflecting a minor difference from the day's peak.

Heat index

August's mean heat index is appraised at a torrid 36°C (96.8°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
One should consider that heat index numbers are for shaded settings and light wind. 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 'apparent temperature', determines the feeling of heat when you account for the relative humidity. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

In August, the average relative humidity is 80%.

Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes. Be attentive! The UV exposure is heightened with reflections from sand and water.
