Weather in August
Temperature
Pontoon Beach's August average high-temperature settles at a moderately hot 84.7°F (29.3°C), showing a near match with the preceding month. During the nights in August, Pontoon Beach observes an average low-temperature of 66.7°F (19.3°C).Heat index
The heat index value during August is estimated at a torrid 95°F (35°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Heat index determinations are made taking into account the shade and light air movements. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to 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.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
