Weather in May
Temperature
With the start of May, Rivière-Salée measures an average high-temperature of a still moderately hot 28.3°C (82.9°F), not significantly differing from April's 27.7°C (81.9°F). Rivière-Salée's nighttime temperature in May shows a minor descent, with a steady average of 26.6°C (79.9°F).Heat index
Throughout May, the heat index is calculated to be a tropical 32°C (89.6°F). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.

January through December, with an average maximum UV index of 7, are months with the highest UV index. January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index value of 6 to 7 symbolizes a high health risk from unsafe exposure to UV radiation for average individuals.Note: In May, an average UV index of 7 transforms into the following instructions:
Ward off overexposure. Defence against solar harm is crucial. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
