April weather forecast
Waigani, Papua New Guinea

The typical weather conditions of Waigani in April mirror those of a tropical region recovering from the monsoon. The regularity of rainfall decreases, paving the way for slightly drier conditions. Temperature readings continue their downward trend started in March, although still comfortably warm. Gusty winds characteristic of earlier months reduce substantially, giving way to calmer breezes. The receding rainfalls allow for more sunshine, instigating radiant afternoons.

Temperature

The transition from March to April brings an average high-temperature of a still warm 29.1°C (84.4°F), barely different from March's 29.3°C (84.7°F). A mean low-temperature of 24.2°C (75.6°F) is a distinguishing feature of April, indicating a slight dip from daytime highs.

Heat index

In April, the heat index is calculated to be a very hot 35°C (95°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Humidity

In April, the average relative humidity is 79%.

Rainfall

In Waigani, in April, it is raining for 24.2 days, with typically 134mm (5.28") of accumulated precipitation. Throughout the year, there are 249.8 rainfall days, and 1311mm (51.61") of precipitation is accumulated.

Sunshine

In April, the average sunshine is 8.7h.

UV index

January, March through May, October through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for average individuals.
Note: In April, the maximum UV index of 7 transforms into these recommendations:
Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
