From what I understand the Oceanfront is opened only for exercise and fishing. That applies to the entire state, from what I understand on the governor's order.
VB sort of went a bit above that and included surfing, since it is a form of exercise.
So with that in mind, I don't think it is a good idea to come down here for the weekend. I don't know about OBX, but it may be better. Also, I don't know if the rules apply to military bases. I have yet to drove into the beach areas to check on that, but I recommend Ft Story beaches as they are just as good as OBX but way less people. They only have a small gas station/PX but it's enough to pack the ice boxes.
Also, keep in mind, Virginia Beach has the highest covid-19 cases in the HR area. Now this might be higher because they're doing more tests compared to the other cities in the HR area, but I suspect that due to the Oceanfront, we're seeing higher numbers. So keep that in mind.
