Clam Tide: Dig Window Guide
Low Water Times for Shellfish
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Clam digger? Pick your species and beach, and Clam Tide turns the tide into a go-or-skip score with your arrival time and how long the dig window stays open today.
Going clam digging? Stop reading raw tide charts and doing the math in your head. Clam Tide turns today's tide into a clear go-or-skip call for the species you're after, on the beach you dig.
Low tide alone doesn't mean a good dig. Every species sits at a different depth and needs a different tide height before its bed is even reachable, and the best time to arrive is usually an hour or two before the low, not the low itself.
HOW IT WORKS
1. Pick your target species and your beach.
2. Clam Tide reads today's tide curve for that beach.
3. You get a Dig Score, your suggested arrival time, and how long the window stays open.
It takes a few seconds to set up. No account required.
CORE FEATURES
Dig Score
A simple GO, CAUTION, or SKIP for today, with the reason in one line: how low the tide goes, how long the window lasts, day or night, and the tidal coefficient.
Species-Aware Windows
Different clams, different rules. Clam Tide knows that a shallow species and a deep one open at different tide heights, and adjusts your window and arrival time to match. Manila, littleneck, cockle, quahog, butter, gaper, razor, and geoduck.
Your Beach
Save your local beach and log your trips. Clam Tide learns how your beach actually behaves and refines your window over time.
