Temperature
With the onset of May, a modest change to a still hot 30.7°C (87.3°F) from
April's 30.6°C (87.1°F) is noted in high-temperature. Madang encounters a steady low-temperature average of 23.9°C (75°F) throughout the month of May.
Heat index
For most parts of May, the heat index is calculated to be a blistering 42°C (107.6°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Heat index determinations are made taking into account the shade and light air movements. 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 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
Humidity
January through May, with an average relative humidity of 85%, are the most humid months.

Note: In May, the maximum UV index of 12 suggests this advice:
Enforce all necessary safety measures, unprotected skin may suffer burns swiftly. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Stay sun-safe with clothing that is both closely woven and worn loosely. Even when it's cloudy, ensure the generous application and frequent reapplication of a sunscreen with at least 30 SPF, particularly post swim or outdoor activity. Warning! The reflection of sand and water increases the UV dose.
