Weather in August

August in Accokeek, Maryland, carries forward the summer's legacy with its hot and humid setup. However, there's a slight dip in temperature compared to July, making the environment slightly more tolerable. The highest rainfall recorded in the year, standing at 3.43" (87mm), makes this month slightly wetter than others. Still, August's weather remains characteristic of the summer season with high heat and humidity being prominent features. It serves as the closing chapter of summer before fall sets in.

Temperature

In Accokeek, August's average high-temperature stands at a moderately hot 85.6°F (29.8°C), closely related to the preceding month. Accokeek records a consistent low-temperature of 67.6°F (19.8°C) during August nights.

Heat index

August's average heat index is calculated to be a fiery hot 95°F (35°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
