Although the rainfall scale tips slightly higher than the previous month, the showers are often brief, offering a soothing effect against the warm weather. Virginia Beach’s sunny skies and azure waters beckon visitors and locals alike to its golden sandy shores. Yet despite the lure of summer, August carries a hint of the imminent fall and its nippy nights.

It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
