The Lowdown
Right then, Rusty here. Let’s be straight with you – this outlook for the next couple of weeks is a tough one. We’ve only got one spot to look at, Harbor House, and the surf is flat or near-flat for the entire 16-day window. There’s no standout, no day where you’d want to drag a board out of the shed. The water temp is sitting at 87°, which is a touch warmer than normal for this time of year, but that’s the only thing of note.
We start off Saturday the 12th with a weak 2ft southeast windswell, period a short 4 seconds. The combined energy is a measly 16 – that’s weak. Add in a risk of thunderstorms and a cross-onshore breeze, and it’s poor. Sunday the 13th is even smaller at 0.7ft, and while the morning has a clean cross-off wind, the swell is just not there. This tiny, short-period energy dribbles on through the week. Monday the 14th through Wednesday the 16th is all 0.3ft to 0.7ft rubbish, with onshore or cross-onshore winds ruining whatever ripple there is.
Then, on Wednesday afternoon the 16th, we see a tiny bump – the swell climbs to 3ft from the NNE, but with a period of just 8 seconds. The combined energy hits 105, which is weak/moderate, but the wind is a moderate cross-onshore. It’s still poor. That very small bump lingers through Thursday the 17th and Friday the 18th, with energy dropping back under 100. By Saturday the 19th, it’s back to 1ft. The rest of the run – from the 20th all the way to the 27th – is a long, drawn-out stretch of tiny, weak surf, with periods mostly under 8 seconds and energy values under 50. There is one brief moment of glassy conditions on the 20th, but the swell is only 0.7ft.
Bottom line: there’s nothing to get excited about. Harbor House is an inconsistent break at the best of times, and this 16-day stretch is a classic blank run for this region. Keep your eyes on the forecast, because it rarely stays this poor for long. Rusty.

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
