The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for your area. I’ve got to be straight with you—this is a rough stretch. The forecast doesn’t offer a single decent surf window across the full 16 days, so we’re looking at a long, quiet spell with no real standouts to get excited about.
Right now, the only spot on the radar is Harbor House, a breakwater setup that’s rated for beginners. It’s inconsistent, and it’s facing east for optimum swell. The problem is, there’s just no energy. The combined swell energy barely cracks double digits, sitting at a weak 5 to 31 (that’s the range you’ll see in the data). Swell heights are tiny, from 0.3 ft to 2 ft, and the period is mostly short—around 3 to 4 seconds—so it’s sloppy windswell, not groundswell. The wind is a mess, too: mostly cross-onshore from the ESE or onshore from the E, blowing at 3 to 16 mph. That’s not cleaning anything up. The water’s sitting at about 87°, which is a touch warmer than normal for this time of year, but that’s the only interesting bit.
From Tuesday, 25 August, right through to Wednesday, 9 September, every single report is “poor surf conditions.” The best you’ll see is a few moments of glassy conditions on the morning of Friday, 4 September, with a 1.0 ft east swell and a 10-second period, but the combined energy is still only 23—too weak to bother with. The rest is just choppy, messy, and not worth paddling out for. This break is fairly exposed, but with nothing coming in, it doesn’t matter.
The area is known for runs like this—when the consistency is low, it tends not to stay poor for long, and forecasts can change. But as it stands, there’s nothing to recommend. If you’re desperate, maybe keep an eye on that Friday morning glass-off, but don’t hold your breath. For now, the boards are staying in the shed.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Harbor House may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
