Weather in August

The last month of the summer, August, is another warm month in Bristol, Maryland, with an average temperature fluctuating between 70.3°F (21.3°C) and 82.9°F (28.3°C).

Temperature

The advent of August denotes an average high-temperature of a still moderately hot 82.9°F (28.3°C), subtly different from July's 84.7°F (29.3°C). During the month of August, the temperature generally drops to a low average of 70.3°F (21.3°C).

Heat index

In August, the heat index is calculated to be a hot 89.6°F (32°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.
Heat index values are typically calculated for conditions of shade and a light breeze. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital 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.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
