One of the hottest months of the year, August is also a middle month when considering severe tropical weather, which does make its way across the Atlantic this time of year. However, such powerful storms are more likely to hit the U.S. coast than the Virgin Islands. Vacationers may experience a slight weather variation from these averages, which are based on St. Thomas' observations.
