The Lowdown
Alright folks, Rusty here. Let's have a look at what Oceanside Harbor has in store for us.
Well, I gotta be straight with you – it’s a tough stretch ahead. The models are showing a long run of mostly small, messy surf, and for the next several days you’ll be hard-pressed to find anything worth paddling out for. We’re looking at a serious gap with no real recommendations until the middle of next week. From now right through to around the 17th of September, the conditions are just not cooperating. The wave energy is moderate at best, with values mostly between 200 and 300 (moderate wave energy), and the wind is stubbornly cross-onshore, chopping up what little swell there is.
The first hint of something more interesting arrives on Wednesday, the 16th of September. We’ve got a pulse of energy showing up with a combined energy of 424 (moderate wave energy). The swell is coming from the SSW at 3ft with a period of 17 seconds. That’s a nice, long-period groundswell. It’ll be clean, with light onshore winds. The water is currently a balmy 73° – that’s much warmer than normal for this time of year, so you might not even need a full suit. The morning session on the 16th is the standout, but don’t expect perfection; the forecast is still a little marginal, and the jetty can be fickle. For the experienced surfer, the long period will create some nice lines along the jetty, but it might close out on the beach. This is the one to watch.
After that, the surf continues to build through the rest of the week, but the wind remains a problem. Thursday the 17th shows a solid 516 energy (moderate wave energy) with a 3ft SSW swell at 16 seconds. The wind is light and cross-onshore, so it’ll be workable but not glassy. It’s going to be a week of ‘almost there’ conditions – you’ll get a few decent waves if you pick your moments.
Into the second week, around the 20th of September, we see the biggest energy of the whole run – 656 (moderate to strong wave energy) on the Sunday afternoon. Swell is from the SW at 3ft and 18 seconds. The wind is light cross-onshore. Again, not perfect, but that’s a lot of water moving. The 21st and 22nd also have decent energy, with the Monday afternoon hitting 650 (moderate to strong wave energy). The long period means it’s best for the jetty, but the crowd situation at Oceanside Harbor can get busy.
Honestly, for the next two weeks, there are no true standouts where everything lines up perfectly. The best on offer is probably the Wednesday morning, the 16th of September, with that 3ft, 17-second SSW groundswell and light winds. It’s the most promising window for a clean session. If you miss that, the weekend of the 20th has the most power, but you’ll be dealing with a little chop. For the beginners, it’s small enough throughout, but the onshore winds will make it bumpy. If the wind keeps up, this spot might be more interesting for the kite surfers than for paddle surfing on most days.
Stay patient, keep an eye on the wind shifts, and I’ll see you out there.
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.
