Weather in August
Temperature
Grantsburg's August reports an average high-temperature of a still hot 86.5°F (30.3°C), exhibiting a minor difference from July. Grantsburg witnesses an average low-temperature of 66.7°F (19.3°C) throughout the month of August.Heat index
Throughout August, the heat index is computed to be a torrid 98.6°F (37°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
