Statistically the greatest wind and waves in the Virgin Islands can be found coming from the ESE.
Sea conditions will always depend on the forecast and the weather many miles away from previous days. In most cases large waves have travelled from storms and winds hundreds if not thousands of miles away. Across the Caribbean the trades and winds generally have an easterly flow. While large waves can come from any direction any time of the year. Anything in the "south" side would be completely unprotected from any wind or wave from the East. The other issue is once outside to the South the line of sight navigation can be very confusing. Unless you truly know how to navigate(following a GPS and computer screen is not navigation) I would not venture in that direction.
The sailing draw of the BVI is the protection offered in Sir Francis Drake Channel and the ability to navigate purely by line of sight.
Here is what you could expect this week sailing offshore to the south of the BVI.
