The Coral Spawning Outlook

The August full moon started yesterday. Here, in the past, the best time to observe mass, broadcast coral spawning and other mass, invertebrate, reproductive behavior has been, just before or after the night's high tide; 2 to 5 nights, after the August full moon. This week, plan on night diving, Tuesday through Friday nights, between 9:30pm and 1:30am. On day dives, look for engorged or enlarged coral polyps in the hard corals and mass spooring from the sponges. A high degree of polyp enlargement or visibly emerging eggs in the polyps, is a good indicator that spawning is imminent.
