Weather in August
Temperature
With average high and low temperatures of 96.1°F (35.6°C) and 73.8°F (23.2°C) respectively, August is Onalaska's warmest month.Heat index
In August, the average heat index is evaluated at a blazing hot 127.4°F (53°C). Stay alert: Heat cramps and heat exhaustion are expected. Heatstroke is a likely outcome of ongoing activity.Given the heat index, its values are aligned with shaded sites and gentle winds. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
