Weather in August
Temperature
August ushers in an average high-temperature of a moderately hot 85.8°F (29.9°C), aligning closely with the preceding month. Throughout the month of August, Kaskaskia witnesses an average temperature of 66.2°F (19°C).Heat index
The average heat index in August is appraised at a very hot 98.6°F (37°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Heat index's context suggests values are appropriate for shady areas and slight breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
