Weather in May
Temperature
Roseland transitions into May recording an average high-temperature of a still moderately hot 81.3°F (27.4°C), closely aligning with the preceding month's temperature. Roseland's nighttime average temperature in May subtly descends to a pleasant 73°F (22.8°C) from the daily highs.Heat index
The average heat index in May is calculated to be a hot 86°F (30°C). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.The standards for the heat index are set for locations in shade and under light breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.

Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. Attention! The combination of sand and water reflections enhances UV ray intensity.
