April weather forecast
Madang, Papua New Guinea

April marks the departure from the uniformity of the preceding months regarding climatic conditions. While the temperature profile remains majorly unchanged, the region experiences an increase in rainfall. This further rejuvenates the marine ecosystem, much to the delight of eco-tourists and conservation enthusiasts. It might interest one to learn that April sees a notable increase in rainfall to a recorded 389mm (15.31"). Irrespective of these weather conditions, April continues to be a month of tranquil interactions with nature.

Temperature

As March turns into April, the average high-temperatures rest at a still tropical 30.6°C (87.1°F), without variation from the prior month. Madang experiences an average low-temperature of 23.8°C (74.8°F) in month of April.

Heat index

In April, the average heat index is evaluated at a scorching 41°C (105.8°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Employ every crucial safety step. Those with fair skin could experience burns in a matter of minutes. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Even on overcast days, apply and frequently reapply a sunscreen with SPF 30 or more, specifically after a swim or outdoor workout. Caution! The Sun's UV rays become stronger due to reflections from water and sand.
