The Lowdown
Alright folks, Rusty here. Let's get into it. Honestly, looking at the whole 16-day window for Oceanside Harbor, I gotta say it's a tough stretch. We've got a real dry spell on our hands, with pretty much nothing worth paddling out for from now until around the 14th of August. That's a full week of poor surf conditions, so don't bother rushing to get your board wet. The water is sitting at 75°F, which is much warmer than normal for this time of year, so at least you can go for a swim.
Things don't really improve much after that either. The whole outlook is plagued by onshore and cross-onshore winds, with the occasional offshore but still weak energy.
Let's walk through it. From Friday the 7th through to Thursday the 13th, every session is marked as "poor surf conditions." The swell is tiny, with heights barely scraping 3 ft from the SSW, and the periods are all over the place, but mostly mid-range. The combined wave energy is moderate, in the 300s to 400s (446), but the wind just kills it. It's cross-on or onshore every single time, making the surface choppy and messy.
You get a slight tease on the morning of Friday the 14th of August. The swell is still small at 2 ft from the SSW, but the energy jumps up a notch (574). The wind is a light cross-onshore, and the forecast just calls it "marginal." It's still not good, but at least it's not a total write-off.
The best chance for anything even remotely surfable comes on Saturday the 15th of August in the afternoon. The swell height bumps up to 4 ft from the SSW, and the combined energy is the highest in the whole run at 734. But, and it's a big but, the wind is still a 9 mph cross-onshore from the W, keeping it choppy. The forecast calls it "marginal surf forecast or questionable tide conditions." So, while it's the biggest, it's far from clean. For a confident surfer, it might be the only window to scratch an itch, but it's not something to get excited about.
The rest of the second week, from Sunday the 16th through to Saturday the 22nd, it's the same story. Swells between 2 ft and 3 ft, mostly from the SSW, with cross-on or onshore winds. The wave energy is moderate (around 400-500), but the quality just isn't there. Every session is marked as "poor surf conditions."
To be honest, with the persistent cross-onshore wind and small, short-period swell, this setup looks more interesting for kite surfing than paddle surfing. There just isn't a standout window for a surfer here. I'm calling it: if you're desperate, maybe look at the Saturday afternoon the 15th, but don't expect much.
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.
