Clamming and Tides: When to Dig

Clamming happens on the beach the water leaves behind. Getting the tide window right is most of the battle.

Low tide is the whole game

Most clam species live in the intertidal zone — the stretch of beach or mudflat that's underwater at high tide and exposed at low. You need the tide low enough to expose that zone, which means checking the tide chart for your specific beach rather than guessing.

Bigger tides expose more flat

A larger low tide (during a spring tide around new or full moon) exposes more flat, further out, for longer. Many experienced diggers specifically plan trips around the lowest tides of the month rather than any low tide, since a shallow neap low might barely uncover the productive zone.

Timing your window

Plan to arrive on the beach an hour or so before the predicted low, giving yourself time to walk out as the water recedes, and build in a buffer to get back before the tide turns and starts covering the flat again. Incoming water can move faster than it looks, especially over flat terrain.

Local rules apply

Regulations, seasons, and closures (including water-quality closures) vary by state and even by specific beach, and change over time. Always check current local shellfish regulations and any posted closures before digging — this guide covers tide timing only, not legal or food-safety guidance.
