Weather in August
Temperature
At the onset of August, Grundy records an average high-temperature of a still moderately hot 82.8°F (28.2°C), showing little deviation from the preceding month. Grundy's temperature in August declines substantially from daytime highs, settling at a consistent average of 59.7°F (15.4°C) during the nights.Heat index
The heat index in August is estimated at a hot 89.6°F (32°C). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
