Remember Sunday afternoons are very bad for crossing back into the US...so it would be wise to stay at least until 7...but 8:30 or later would be best.
You might want to go around 1pm and scout around, just realize that with each hour there will probably be some new chicas showing up at any given bar...so don't be afraid to check back later.
