Weather in August

Cambridge, Maryland, views August as a continuation of the sweltering summer trend from July. The heat lingers on, marking the last full summer month before a welcomed shift in weather. August demonstrates high-temperature days, paving the way to relaxing, cool nights, assisting after sundown outdoor events. Despite sharing similar temperature records with July, August distinguishes itself with more rainfall. With a maximum temperature of 83.1°F (28.4°C), the month results in days of sun-soaked fun and sultry nights echoing the summer's last full blast.

Temperature

August notes an average high-temperature of a still moderately hot 83.1°F (28.4°C), subtly differing from July's 84.6°F (29.2°C). An average minimum temperature of 69.4°F (20.8°C) is recorded during the month of August.

Heat index

The average heat index in August is computed to be a tropical 91.4°F (33°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
