The Lowdown

Right. Rusty here. Gotta be straight with you – this 16-day stretch for Oceanside Harbor is a tough one. It’s a beach and jetty setup that’s exposed to the west, and the swell we’re getting is coming in from the south-southwest and southwest. That’s a tricky angle for this spot, and the winds are almost always messing it up. There’s a real long gap of nothing worthwhile right from the start.

You’re looking at a solid week of just poor surf conditions starting Sunday the 9th of August. The swell is tiny – around 3ft to 3ft – and it’s getting chopped up by cross-onshore winds. The wave energy is moderate at best. Don’t even think about paddling out.

The first flicker of something happens on Friday the 14th of August. The swell is still small, around 2ft to 3ft from the SSW, but the period is a nice long 18 seconds – that’s proper groundswell energy. The combined energy jumps up, getting stronger. But the wind is still a cross-onshore breeze, so it’s going to be messy. It’s only a “marginal” call. Not a standout, but the best of a bad bunch for the first week.

Then, the whole second week is pretty much a write-off. From Sunday the 16th of August right through to Monday the 24th, it’s all “poor surf conditions” with tiny swell and persistent onshore or cross-onshore wind. The energy drops back down. There’s a tiny pulse on Saturday the 22nd of August morning with a very long 21-second period, but the swell is only 1ft – too small to do anything with.

Honestly, there’s no true standout window here. If you’re desperate, the best chance is the morning of Friday the 14th of August. That 18-second groundswell will have some push, but the cross-onshore wind will keep it from being clean. For a jetty, a long period swell can wrap in, but the wind will kill the shape. The water temperature is a very unusual 76°F, which is much warmer than normal for this time of year, so at least you won’t be cold while you’re sitting there disappointed.

Because the winds are so consistently poor for this exposed beach setup, it might actually look more interesting for kite surfing than paddle surfing on most of these days. Save your energy.

Rusty.

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.
