Weather in May
Temperature
May's presence marks an average high-temperature of a still warm 28.9°C (84°F), subtly varied from April's 29.1°C (84.4°F). Waigani reports an average low-temperature of 24.1°C (75.4°F) during the subtly cooler May nights.Heat index
For most parts of May, the heat index is calculated to be a hot 34°C (93.2°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
