Best fishing times at Mount Sinai Harbor (solunar table)
Major periods, about two hours each, are centered on the moon passing overhead or underfoot. Minor periods, about an hour, are centered on moonrise and moonset. By solunar tradition the days around the new and full moon are the strongest, and many anglers plan for a major period that falls on a moving tide.
