The Lowdown

Alright, Rusty here. Let's have a look at what's on the cards for the local stretch.

To be straight with you, the next couple of weeks are looking pretty ordinary for a proper paddle session. The swell is around, but the wind is just not playing ball for most of it. The water’s about average for this time of year, nothing unusual there.

The best chance of a decent wave, and it's a long shot, is on Tuesday the 25th of August. We've got a small 4ft swell from the west, with a short period of 7 seconds, so it'll be a bit weak and lumpy on the face. The big win here is the wind: it's glassy, absolutely dead calm. That will make it super clean, even if the waves aren't packing much punch. The combined energy of all swells is weak (164). It's a beginner-friendly spot, so it'll be a good one for a gentle cruise, but don't expect any barrels.

The rest of the period is a write-off. From Saturday the 22nd right through to the end of the month, we're hammered by fresh to strong cross-shore and cross-onshore winds, with a lot of chop and messy conditions. There's a big pulse of swell coming in around the 3rd, 4th, and 5th of September, with waves hitting 7ft to 8ft, and even 10ft on the 6th, but the onshore wind is just ruining it. The combined energy gets strong, hitting 1254 on the 4th, but it's all blown out. That 10ft on the 6th is too big for this break anyway, and the wind is still cross.

So, honestly, there's one small window of glassy, small surf on Tuesday the 25th. If you're desperate for a paddle, that's your best bet. Otherwise, the rest of the 16 days are a right-off for decent surfing.

Rusty.
