Weather in August
Temperature
August's arrival registers an average high-temperature of a still warm 82.8°F (28.2°C), closely aligning with the temperature of the previous month. In White Marsh, August nights cool down to an average of 67.6°F (19.8°C).Heat index
The heat index value during August is evaluated at a tropical 89.6°F (32°C). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.

Fend off overexposure. Sun protection is vital. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak.
