Under the right conditions, the tidal change there can be as much as 8 feet. Same holds true with several other inlets farther south. I never understood why, for example, at Cape Charles Harbor the tidal change was less than 3 feet, while just across the peninsula not three miles away at Oyster, the tidal change could be as much as 12 feet. Just another unexplained phenomena of nature that drives us crazy.
If you're headed south from Ocean City, and wanted a sheltered area to spend the night, the hook just before entering Toms Cove has about 20 feet of water relatively close to shore. It's sheltered fairly well from an easterly and northerly wind. For me, I would prefer easterly, mainly because the national bird of Chincoteague is the mosquito. They can really be bad when the wind's blowing from the southwest or any westerly direction.
