Weather in August
Temperature
August, recognised by an average high temperature of 91.9°F (33.3°C) and a low of 74.1°F (23.4°C), is McHenry's warmest month.Heat index
August's heat index is estimated at a burning hot 116.6°F (47°C). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
