The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on the menu for Oceanside Harbor over the next couple of weeks.

Honestly, it’s a pretty flat and quiet stretch ahead. The water is sitting at 75°, which is much warmer than normal for this time of year – feels like a bathtub out there.

The first bit of surf we see is on Wednesday afternoon, July 29th. We’ve got a long-period SSW groundswell pushing in at 4 ft, with a 16-second period. That long period means the waves will have some real energy, but at a beach/jetty setup like this, it can make things a bit too straight. The combined energy is strong, reading 1016. Winds are light and cross-onshore, so it’ll be a bit bumpy. This is really only for the advanced crew.

Thursday the 30th sees a drop in size. Morning starts with 3 ft from the SSW, with a light offshore wind – that’s a major positive, meaning clean conditions. The energy drops to 798. The afternoon bumps up slightly to 3 ft but the wind swings cross-onshore, making it choppy. It’s marginal at best.

Friday the 31st is more of the same: 4 ft in the morning with a light cross-onshore breeze, fading to 3 ft in the afternoon. By Saturday, August 1st, we’re down to tiny 2 ft waves with poor conditions. From there, the next week is a real struggle. From August 1st through August 13th, the swell barely gets above 3 ft, with most days seeing 1 ft to 2 ft. The combined energy values are mostly in the low 100s to mid-400s, which is weak to moderate at best. Winds are generally light, but the direction is often onshore or cross-onshore, keeping things messy.

There are a couple of flickers of hope. On Friday, August 7th, we see a 19-second period swell, but it’s only 2 ft – all that long-period energy (410) but no real height to work with. Then on Monday, August 10th, the afternoon shows a 20-second period at 2 ft, but it’s a similar story. It’s just not enough to get excited about.

The standout, if you can call it that, is the very first window on Wednesday afternoon, July 29th. That 4 ft at 16 seconds is the biggest and most energetic swell of the entire run. But with the cross-onshore wind and the advanced-only nature of the break, it’s not a session for the masses. The crowds are often there, so expect company.

Overall, it’s a lean 16 days. The best bet is to keep an eye on the forecast, because this kind of flat spell can’t last forever.

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.
