Obviously completely dependant on the tide and the swell at sea. It requires two big waves from different directions to smack into each other at exactly the right place just at the mouth of the channel for a good "BOOM" and a jet of water, spur, steam, to shoot up to 30 m into the air.
If its low tide and calm, forget it. If its June monsoon storms, get down there. We were lucky, we saw big stuff in Jan.
Lots of crumbly steps, look out.
