The Lowdown

Alright, Rusty here, checkin’ in with a look at the next couple weeks for our local haunts. Let’s be real, this ain’t gonna be one for the history books, but there’s a few windows where it might just be worth paddling out.

Right off the bat, Monday the 24th has some tiny lines, but the reports are callin’ it poor. Not worth wetting the wetsuit for. We’ve got a long, drawn-out stretch of weak, marginal conditions, with the real story being the water. At Oceanside Harbor, that water is sitting at 74°F – a massive 7°F warmer than usual for this time of year. It’s honestly weird, like summer held on way too long. Feels more like a bath than the ocean.

The whole first week is just dialed in on that one break. We’re looking at a mix of SW and S swells, mostly in the 2ft to 4ft range. The period is all over the shop – some 18-second groundswell lines on Tuesday the 25th, which is pretty, but the energy is still weak (combined energy around 357-400). Then it drops to shorter 12-13 second wind swell. The winds are mostly light, which is good, but they’re almost always cross-on or just on, so it’s gonna be a bit lumpy. Nothing is clean enough to get excited about. By the end of the first week into the weekend of the 30th-31st, it honestly just looks poor again.

There is a flicker of something better towards the end of this outlook. The best bet, if you can wait, falls on the 4th of September. Oceanside Harbor picks up a solid SSW swell bumping to 4ft+ with a 17-second period. That’s a real groundswell, and the combined energy jumps into the strong zone at 1124. The wind is a light offshore from the SW in the morning, which is about as clean as that jetty gets. It’s only a “marginal” call, but that’s the standout of the whole 16 days by a long shot. It might get a bit crowded there as it’s often got a crew, but on a morning like that with clean lines, it could be a gem.

Following that, the 8th of September holds similar promise for the morning with 5ft from the SSW, 13-second period, and light offshores again. The energy is still strong (956). It’s another one to circle on the calendar.

So, to be straight with you: the first week and a half is largely a skip. No standouts. Wait for that early September window, especially the 4th and the 8th. It’s not a guaranteed firing session, but it’s the only time the pieces look like they might actually fit together.

Information about the Oceanside Harbor Surf forecast

The above surf forecast table for Oceanside Harbor provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Oceanside Harbor can be found by selecting the local surf guide option on the grey menu. Our Oceanside Harbor surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Oceanside Harbor) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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 Oceanside Harbor 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.
