The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Oceanside Harbor over the next couple of weeks.
To be straight with you, the outlook is a flat spell for most of the run. The opening days of the forecast, starting Wednesday July 29th, have a little bit of energy but not enough to get excited about. We’re looking at a long gap of poor surf from the 1st of August all the way through to the 13th, with most days offering nothing rideable. Don’t get your hopes up for any standout sessions.
The only real pulse of life comes on Wednesday July 29th. In the morning, we’ve got a 4 ft swell from the SSW, with a very long 16-second period. That’s a proper groundswell, but the energy is moderate at 645. The wind is light and offshore from the SW, which is a big plus—it’ll keep the surface glassy. The afternoon bumps up to 4 ft SSW, with the same 16-second period, and the wave energy climbs to a solid 1017. Winds stay light offshore. This is a beach/jetty setup, so with that long period, the sets might be a bit walled up, but for a bowl or two, this is the best you’ll see. The water temp is about average for the time of year.
Thursday the 30th drops off a bit. Waves are 3 ft to 5 ft from the S/SSW, period still long at 14-15 seconds, but the cross-onshore wind will put a ruffle on the surface. Not terrible, but not clean. It’s really just a shadow of what Wednesday offered.
Friday the 31st is similar, with 4 ft to 5 ft from the SSW, period dropping to 13 seconds. That cross-onshore breeze is still there, so expect some bump. Not a day to race down.
From Saturday August 1st right through to Tuesday August 12th, the swell vanishes. Heights are mostly 1 ft to 3 ft, with period values all over the place, but the energy is weak (under 400) and the scores are all zero. It’s a long, flat, poor stretch. There’s nothing to recommend here. Even the occasional longer-period swell on the 7th and 8th does nothing for the size.
The very end of the run, Wednesday August 13th, still looks poor. 3 ft from the SW, 16-second period, but the energy is moderate at 417, and the wind is offshore. Still, it’s not enough to call it a session.
So, bottom line: if you’re itching for a paddle, point your board at Wednesday July 29th. The rest of the window is a write-off for surf. Keep an eye on it, because forecasts can change, but right now, it’s a long gap.

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.
