Weather in May
Temperature
Observing a slight rise in May, the average high-temperature shifts from April's warm 77.9°F (25.5°C) to a still moderately hot 85.3°F (29.6°C). Throughout May, River Falls registers a distinct decrease from daytime highs, reaching an average low of 63.3°F (17.4°C).Heat index
May's average heat index is evaluated at a tropical 93.2°F (34°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.One should consider that heat index numbers are for shaded settings and light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
