How these times are worked out
Major periods are the two hours centred on the moon passing overhead or underfoot; minor periods are the hour centred on moonrise and moonset (solunar tables). Moon and sun times are computed for this station’s position with the PyEphem astronomy library; high and low tides are NOAA predictions. A period is marked best bet when it overlaps sunrise or sunset (within an hour) or contains a high or low tide. This is a traditional angler’s rule of thumb, not a guarantee, and it does not include weather, season or local rules.
