Most clam digging must take place during minus tides. These tide come in sets. During the spring and early summer there are usually two sets of minus tides a month, and typically the lower the tide, the better the clam digging. This year there are two sets of minus tides June 8-15, the second is June 21 to 28. Check a tide book for specific water height asnd time.
Clams are subject to concentrations of both natural and man-made toxins.
Warm, waterproof clothes are the normal dress code. Wear rubberized raingear and chest waders. You can get by with less, but be prepared to get wet and cold. Wear a stout pair of gloves to twist mussels from the rocks. Some people wear gloves when digging bay clams, but most find them a hindrance and use their bare hands.
