Alright, let me break down what’s going on at Oceanside Harbor for the next couple of weeks. It’s a pretty quiet stretch overall. There’s nothing worth paddling out for right now, and it takes a while before we see anything that’s even marginal. The first real chance to get wet is Monday, July 6th, but don’t expect much.

From July 3rd through the 5th, it’s all poor. The swell is coming from the SSW with a long 16 to 18-second period, but waves are only 3 to 3 feet. The wind is from the west and west-southwest, keeping the surface choppy. The combined energy is moderate, between 391 and 476, but the surf quality is just not there. You’re better off waiting.

On Monday the 6th, conditions get a little less bleak. Swell is still small—about 3 feet from the SSW with a 16-second period. Water temperature is pretty typical for this time of year, nothing unusual. The wind is light and onshore in the morning, then light cross-onshore by the afternoon with a few ripples. Combined energy picks up to between 519 and 647 (moderate), but the surf is still marginal and the tide might mess with it.

Tuesday the 7th is our best bet. Swell nudges up to around 4 feet from the SSW with an 18-second period. Combined energy comes in at 820 to 866 (moderate). The wind stays light, onshore in the morning and cross-onshore in the afternoon. It’s still not great, but it’s the biggest swell of the whole two weeks.

Wednesday the 8th and Thursday the 9th keep similar size—3 to 4 feet from the SSW, with 16-second periods—and light onshore breeze. Still only marginal quality.

Then things drop off fast. From Friday the 10th right through to Saturday the 18th, it’s back to small, poor conditions. The one exception is the afternoon of Wednesday the 15th, where the wind goes glassy and the swell is small—1 feet from the SW with a 17-second period. The combined energy is just 195 (weak), but it’s clean. Tiny though.

So if you want the single best session of the outlook, it’s Tuesday the 7th of July. Swell size is 4 feet from the SSW (the optimum direction here is west, so it’s a little off, but still the biggest). The 18-second period gives some real push. Light winds keep it from being total chop. Combined energy hits moderate levels. It’s not a standout day, but it’s the best on offer. Expect crowds because this spot is often busy. The beach/jetty setup means the long period might offer some shape on the right tide, but it could also be a bit walled up.

The second week is even weaker. Honestly, for this stretch, with the small waves and wind, a kite might be more entertaining than a paddle board.

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.
