Coral Spawning Tours

Coral Spawning is an annual nocturnal phenomenon that creates the most amazing underwater show not to be missed. Coral Spawning occurs only a few nights every year (usually in November), when many coral colonies simultaneously release egg and sperm bundles for external fertilization. Visitors from all over the world come to experience and watch the miracle of this life cycle, often described as an upside down snowstorm as the water fills with brightly coloured micro polyps.

There are a few indicators that assist scientists in the difficult task of predicting when coral spawning may occur each year, although the exact dates can never be guaranteed - it is all up to mother nature. Contributing factors are that the oceans temperature needs to be 26 degrees Celsius or above for the month before, allowing the sperm and eggs to mature. Secondly, they will generally spawn 4 to 7 nights after the full moon in late spring/early summer when there is little tidal movement. Thirdly, it will usually be about 2-3 hours after the sun sets, as most of the plankton feeders will be asleep and it allows the fertilized eggs to settle back down to the relative safety of the reef.

To catch this unique natural wonder of coral spawning, you need patience and just a little bit of luck.
