Not sure when they start up in the morning, but I know they go until 7:00pm. All rules still apply though, so no reason to change anything. We actually notice more people swim out further and a lot more scattered when the guards leave. Paul (zulutimer) and I had to quit when the sun was going down the other day because a head would bob here and there and we just weren't having that.
