Weather in August
Temperature
An average high-temperature of a still hot 86°F (30°C) marks August, exhibiting a close resemblance to the conditions in July. In Madison, the nighttime temperature registers a significant drop from daytime peaks to an average of 64.4°F (18°C) in August.Heat index
The average heat index in August is evaluated at a fiery hot 96.8°F (36°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
