The Lowdown
Alright folks, Rusty here. Let’s have a look at what Oceanside Harbor has in store for us over the next couple of weeks. I gotta be straight with you—this is a tough outlook. The pattern is pretty flat and uninspiring right through.
For a spot like Oceanside Harbor, a beach/jetty setup that’s exposed to the west and southwest, we need a decent push of swell and clean winds to get it going. The first week and a half is a write-off for any kind of decent surf. The combined swell energy sits in the low to moderate range, mostly between 128 and 447, which just isn't enough to push through. The water temperature is sitting at 76°, which is a massive 8° warmer than usual for this time of year—very unusual, you’ll be stripping down to boardshorts for sure, but the surf won’t be cooperating.
There’s a long gap with zero recommendations. We’re talking day after day of "poor surf conditions." The swell is tiny, mostly between 1ft and 3ft, and the period is all over the shop. You’ll see some longer period groundswell in there, 15 to 19 seconds, but without any size, it’s just not doing anything. The wind stays light and mostly onshore or cross-onshore, which just keeps the surface messy. Nothing to get excited about.
The one and only faint glimmer comes right at the very end. On Saturday, August 15th, in the afternoon, we finally see a combined energy reading of 558, which is moderate-to-strong energy. The swell bumps up to a full 3ft from the SSW, with a 16-second period. But the catch? The wind is cross-onshore from the west at 9 mph, and the conditions are described as "gentle cross-onshore and fairly choppy." It’s only scoring a 1 out of 10, and that’s for "marginal surf forecast or questionable tide conditions." So, while it’s the best we’ve got, it’s not exactly a standout, and it’s over a week away, so the long-range certainty is low.
For beginners, stay home. The swell is too small anyway, and when it does show a pulse it's only 3ft, which is borderline okay, but the onshore wind ruins it. For experts, there’s nothing here that’s going to get your heart pumping. Honestly, with the consistent onshore flow and small swell, this setup looks more interesting for kite surfing than paddle surfing right now.
So, to sum it up: a long, dry spell with no real surf on offer until maybe the afternoon of Saturday, August 15th, and even then it’s marginal at best. It’s a frustrating forecast, but that’s how it goes sometimes.
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.
Oceanside Harbor is 8 km (5 miles) from the city of Oceanside. If you plan a vacation in San Diego County, look for hotels and other accommodation in Oceanside. Oceanside has rooms for a wide range of budgets as well as car hire and transport links.
