I think that is just about the quickest turnaround I’ve seen in many a long year. Utterly and completely flat at 1100 this morning when mate Barry and I were walking out along the rocks at the point. We were within two metres of the water and in no danger of a rogue splash. I just watched a set with a good solid 6 to 8 foot of face (trough to crest, not back) wall into Dee Why beach and hone left for a hundred metres. Four hours ago you couldn’t have caught anything even with a SUP at that same spot.
The MHL buoy tells the tale. Swell ramped from less than a metre at 6 seconds to nearly 2 m at 11 seconds. At the same time it swung a little east so that it should be lighting up lots of spots – not just DY.
Might go for a closer look to see what else is going nutty just at the moment.
