May weather forecast
Sataua, Samoa

Sataua's climate in May reflects a shift away from the preceding month's weather trends. The significant reduction in the volume of rainfall appears to be the most evident change observed in this month. Despite this, the region witnesses cloud coverage of nearly 44%, contributing to a partly cloudy environment. Unlike the previous months, the intense sunlight hours shorten, however, residents and tourists still need to be mindful of the consistent UV index of 7. Even though the wind flow changes and increases to approximately 20.1km/h (12.5mph), it continues to offer a refreshing contrast to the warm environment.

Temperature

The transition into May shows a subtle variation to a still moderately hot 27.3°C (81.1°F) from April's 27.5°C (81.5°F) in the average high-temperature. Registering an almost steady temperature, Sataua's nights in May see an average low of 26.3°C (79.3°F).

Heat index

The heat index value for May is calculated to be a tropical 31°C (87.8°F). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.
In terms of the heat index, values are set with light wind and shade conditions in mind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
