Winter tides
In the winter the low tides are in the middle of the night. The clams are safe. The highest tides of the year come in January and February. Depending on the wind, they can clog the beach with driftwood or they clean it off, but there’s not much point in spending a day cutting up driftwood to clear a spot for the supply barge if the logs are just going to float back in. Better to wait until March for the big loads.
