Weather in August
Temperature
With August's advent, Saint Marys sees an average high-temperature of a still hot 90°F (32.2°C), subtly shifted from July's 90.1°F (32.3°C). During August, Saint Marys records an average temperature of 76.8°F (24.9°C) at night.Heat index
The average heat index in August is evaluated at a blistering 111.2°F (44°C). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.Take into consideration that the heat index values are calculated for shade and light wind conditions. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. 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.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Deter overexposure. Protecting against the sun's effects is essential. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
