Weather in May

In Mulinu'u, May experiences a downward slope in maximum temperature reading 28.3°C (82.9°F), a hint at the introduction of cooler climes.

The uniformity in the UV index calls for regular use of sunscreen for skin health, despite the cloud cover.

Temperature

The average high-temperature is a still moderately hot 28.3°C (82.9°F) in May, hardly different from the 28.7°C (83.7°F) recorded in April. Nighttime temperatures record an average of 27°C (80.6°F) throughout May.

Heat index

The heat index in May is estimated at a tropical 32°C (89.6°F). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.
Take into consideration that the heat index values are calculated for shade and light wind conditions. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
