In the event you aren’t too au fait with deciphering these sorts of charts, this data is basically suggesting that we’ve got waves incoming in Sydney.
Once the lines on that bottom graph cross over the 10 second mark you can usually expect some powerful groundswell to start arriving at the beach soon. The upper chart is showing that we got a change in swell direction with the newly arriving swell coming from the dead South and it’s 2-3 metres. What all this translates to (when taken in context with the weather report and charts) is that we’ll start seeing some decent sized waves, probably in the head high region, over the next few hours, and biggest on the south facing beaches like Avalon, Curl Curl, Long Reef and Bondi.
At 225pm not much appearing at Dee Why but you can see some activity up toward Long Reef. Bad new is that the wind is forecast to build along with the swell, also from the S to SE, so while we can expect some waves, we’ll also find that they could be pretty chopped up by the wind everywhere except protected corners like Dee Why or the Bower.
