Winona's weather in June shows a rise in the average high-temperature, moving up from May's warm 75.7°F (24.3°C) to a tropical 86°F (30°C). Winona's average low-temperature for the month of June records at a comfortable 64.8°F (18.2°C).

Heat index

In June, the heat index is estimated at a torrid 98.6°F (37°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
