Weather in May
Temperature
As April transitions into May, Onalaska notices a gentle rise in the average high-temperature, transitioning from a warm 78.3°F (25.7°C) to a hot 86.2°F (30.1°C). May brings an average low-temperature of 65.5°F (18.6°C) to Onalaska.Heat index
In May, the average heat index is evaluated at a very hot 98.6°F (37°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Consider that heat index readings are for situations in the shade and light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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 especially vital to children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Resist extreme sun exposure. Guarding against solar damage is essential. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
