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

Madang begins April with an average high-temperature of a still hot 30.6°C (87.1°F), echoing March. Madang cools down to an average low-temperature of 23.8°C (74.8°F) throughout the month of April.

Heat index

During April, the heat index is calculated to be a blistering 41°C (105.8°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Carry out all crucial safety measures, unprotected skin may burn instantly. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation. Even on cloudy days, a sunscreen with a minimum 30 sun protection factor should be generously applied and frequently re-applied, including after every swim or outdoor exercise. Be vigilant! The Sun's UV rays get a boost from sand and water reflections.
