Weather in May
Temperature
As April gives way to May, the average high-temperature displays a slight ascent, adjusting from 75.9°F (24.4°C) to a still moderately hot 84.2°F (29°C). In the month of May, Winona's average low-temperature falls to a refreshing 63.3°F (17.4°C).Heat index
During May, the heat index is computed to be a hot 91.4°F (33°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
