April weather forecast
Port Moresby, Papua New Guinea

Heading into April, the rainfall volume dramatically reduces to 134mm (5.28") from the previous month. The city starts to experience lower high temperatures, down to a pleasant 29.1°C (84.4°F). Consequently, activities that require cooler conditions may thrive better. As the daylight hours decrease, so do the humidity levels, making the weather more bearable and enjoyable. Thus, the month of April denotes a transitional period from the monsoon season to slightly cooler temperatures.

Temperature

The transition into April in Port Moresby reveals an average high-temperature of a still warm 29.1°C (84.4°F), mirroring a close resemblance to March. April nights cool to an average low-temperature of 24.2°C (75.6°F), a marginal decrease from its daytime equivalent.

Heat index

The heat index value during April is appraised at a sweltering 35°C (95°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely vital to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. To cut down UV radiation exposure by about half, sport a wide-brim hat. Beware! Reflecting off water and sand, UV rays are much stronger.
