In the summer, when you see that weed coming in, the sand is usually coming in with it. It's starting here as well, everything being pushed straight in with no cross currents to do any type of cutting or redistribution. This is really common during those summer negative low tides, which we are having right now. Once this negative cycle starts to fade back into positive tides all of this sand and weed will start to get cut and redistributed again as the "lone shore" currents and "rips" start to move back in along the beach due to the increased volume of water and increased force of the surf. Personally, I don't like the negative tide cycles just for this reason, too much soft sand piling up everywhere and anything fairly dense sinking rather quickly. Makes for some really comfortable and easy water hunting, for sure, but good targets are usually much harder to come across, especially in the water. Once the heavier volume and force returns to the beach it will often create low spots, cuts, etc., in this soft sand buildup and expose a lot more targets that you couldn't get at during the negative tide period. These heavier surf conditions will also serve to scatter a lot of items like coins on the beach. Of course, this is the typical run of things on my area beaches so yours might be a little different but probably not a whole lot.
