This Pismo tides chart lists every clammable low tide at Pismo Beach for the current and following year. Because you can only dig at low tide — never at high tide — every entry meets two conditions: the low tide must occur between sunrise and sunset (since clamming is permitted only from one half-hour before sunrise to one half-hour after sunset, this guarantees a full half-hour of legal working time on either side of the low), and the tide must be +2.0 ft MLLW or lower (the practical upper limit at which clams can still be reached).
Tides are color-coded by working depth. When the National Weather Service issues a high surf, beach hazard, or coastal flood alert covering Pismo Beach, the affected dates are recolored red and labeled with the alert type — check back close to your planned date.
Found a low tide? That's when you dig.
Low tide is the whole game — it's the only time Pismo clams are reachable. Once you've picked a date above, read how to dig Pismo clams for the technique, and check the gear you need before you go — the fork and 4.5-inch gauge are required on the beach.
