Weather in August
Temperature
Saint Charles records an average high-temperature of a warm 85.5°F (29.7°C) in August, maintaining a close correlation with July's 86.4°F (30.2°C). The average temperature during August nights is registered at a comfortable 66.7°F (19.3°C).Heat index
The heat index value during August is computed to be a very hot 96.8°F (36°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
