I am assuming you are certified. But that being said I would always dive with a buddy next to you. There are a lot of things that can go wrong even in shallow water and shore dives. You still may become entangled, injured, or swept away in a current. Take a buddy you trust, and stay together, have a signal devece that can be seen from the shore or a boat You may also want to do a few dives with a local instructor or group to familarize youself with the area you will be diving in. I personally would never dive in a new area without first diving the area with a qualified local to familarize myself with the area and risks specific to the area (unless I had to make the dive for some reason).
