How Tides Affect Shelling
Tides move shells from the seafloor to the shore and back again. Understanding the cycle helps you be in the right place at the right moment.
Why Low Tide Wins
As the water recedes, it drops shells along the exposed sand and leaves the wrack line — a band of seaweed and treasures marking the high-water mark.

Follow the curving line of debris left by the highest tide. It concentrates shells, sea glass, and other finds in one easy-to-search ribbon.
Spring vs. Neap Tides
- Spring tides (around new and full moons) have the widest range and expose the most beach.
- Neap tides have a smaller range and reveal less shoreline.
- Check a local tide chart and plan your walk for the lowest low of the day.
