Coral Spawning was first scientifically witnessed 30 years ago by several marine biologists working on the Great Barrier Reef. It's Mother Nature's way of maintaining a consistently robust coral gene pool. Predicting when the coral spawing will occur is not an exact science but does rely on several environmental cues. The ocean temperature needs to be 26 degrees celcius or above for the month before for the gametes to mature. Secondly, they will generally reproduce 4 to 6 nights after the full moon in November or December when there is little tidal movement. Thirdly, it will generally be about 2-3 hours after the sun sets, because it's nice and romantic!, but more importantly most of the plankton feeders will be asleep, giving the eggs more time to settle to the relative safety of the reef.
