The Lowdown
Alright, Rusty here. Let’s talk about the local surf scene, and I’ll be honest, it’s looking pretty flat and messy for the next couple of weeks.
We’ve got a long gap with no real surf on offer. The first chance to even think about it is a marginal call on Friday, August 14th. Before that, from the 7th through the 13th, it’s all poor conditions.
The only break we’re looking at is Oceanside Harbor (Oceanside-Harbor). It’s a beach and jetty spot, very consistent, but it’s exposed to the west. That’s the problem – the wind is blowing from the west and southwest for most of this period, putting it straight onshore or cross-on, messing up the surface. The water temp is about 75°F, which is way warmer than normal for this time of year – almost 8°F above average.
Let’s break it down. From Friday, August 7th, through Thursday, August 13th, it’s a total loss. The swell is tiny, 2 ft to 3 ft from the SSW, with long periods (13-20 seconds). The combined wave energy is in the 320 to 432 range (moderate energy), but it doesn’t help because the 9 mph westerly wind is putting a chop on everything. The report says “poor surf conditions” every single day.
On Friday, August 14th morning, we get the first marginal call. The swell is still small at 2 ft from the SSW, with an 18-second period, and the energy bumps up to 571 (moderate energy). The wind is still cross-on from the west at 9 mph, so it’ll be bumpy, but you might find a wave if you’re keen. The afternoon is back to “poor.” Saturday, August 15th, and Sunday, August 16th, see the swell size creep up to 3 ft - 4 ft, and the energy climbs to 656-722 (moderate energy), but the wind is still a cross-on mess. It won’t be clean.
From Monday, August 17th, onward, it’s the same story: small swell (2 ft to 3 ft), mostly SSW, with the wind either onshore or cross-on. The combined energy drops back to 199-393 (weak to moderate energy). The last few days, from the 20th to the 22nd, are just more small, choppy slop.
Because it’s a beach and jetty break, and the swell is too small with the wrong wind, this setup honestly looks more interesting for kite surfing than paddle surfing right now. The long period swells (15-19 seconds) we’re seeing would be great for a point or reef, but at a beach break with this wind, they’ll just close out.
There’s no good surf on offer. It’s a real blank run. Sometimes it just goes flat and messy, and that’s what we’ve got. Stay tuned, 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.
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.
