Since you normally have an onshore wind in the afternoon, it's best to anchor with the bow facing offshore.
We used to put the bow anchor down regardless of the direction of the current and then wade or swim the stern anchor to the beach. After pulling the stern around toward the beach, we would then bury the stern anchor in the sand. That way, the boat isn't going to go anywhere as long we had enough scope out off of the bow. We would use at least 7X the depth of the water for the scope off the bow anchor. Since the stern anchor was buried, it didn't mater how much scope was used at the stern. But the stern needed to be far enough off the beach so that it would not come close to the sand in the event that the tide went out.
Never had a problem in 14 years. Even during bad thunderstorms.
Having a windlass, pulling the boat way from the beach should be a piece of cake.
