The Lowdown
Alright, listen up. It’s flat out there. For the next week and a half, the ocean is just going to be sleepy. We’re looking at tiny, weak swell, mostly under 3ft, and the wind is going to be all over the place. It’s mostly blowing onshore or cross-onshore, which chops up what little energy there is. We’re talking weak energy readings too, mostly in the single to low double digits, which is just nothing to get excited about. There’s a brief chance of a storm on Wednesday and Thursday this week, but it’s not going to produce any surf for us, just some messy conditions. If you’re a beginner, there’s nothing here for you, and even the experienced guys are going to be struggling. The water's a touch warmer than normal for this time of year, about 1° above average, hitting 87°F, so that’s nice for a swim, but there's no surf to be had.
The real story is a solid pulse of new energy that shows up on the 21st of September, which is a Monday. That’s just over a week away. Swell heights jump to 4ft to 5ft, coming from the NNE with a period around 9-10 seconds. The energy readings finally get into the moderate to strong range, hitting 203 and then 450, which is a legitimate jump. That’s the day to circle on the calendar. The 21st looks like it has the best combo with the biggest swell and strongest energy. It’s not perfect, with the wind still being a bit of a factor, but there will be waves.
Following that, through Tuesday the 22nd and into the 23rd and 24th, the swell stays in that 4ft to 5ft range, but it gets messier as the wind turns more cross-onshore and picks up. That NNE direction is okay for this spot, but the cross-shore wind on the 24th could make things lumpy.
The standout, if you can call it that, is Harbor House on the 21st of September. That’s the only day where the energy and size come together to make it worth a look. It’s a breakwater, so it can be inconsistent, and with the swell direction being NNE and the period at 10 seconds, it might be a bit straighter at a beach setup, but it’s our best bet. Crowds are possible, so get down there early. The 22nd is next in line, but that cross-on wind is going to make it a bit more of a battle. The swell is over 5ft on the 21st afternoon, so it might be a bit much for the groms, but for everyone else, get on it.

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.
