The Lowdown

Alright folks, Rusty here. Let's have a look at what's cooking for Oceanside Harbor over the next couple of weeks.

Right off the bat, I gotta be straight with you – it’s looking pretty bleak. The first week and a half is a total write-off. From Wednesday the 5th all the way through to Thursday the 13th, we’ve got nothing but poor surf conditions with scores of zero. The swell is tiny, mostly around 2ft, and the wind is either onshore or cross-onshore from the WSW or SW, just chopping everything up. The combined swell energy is weak to moderate (values between 142 and 597), but it doesn’t matter because the quality is just not there. It’s a frustrating stretch, almost 10 days of flat, messy dribble. Not even worth paddling out for.

Now, the tide starts to turn a little on Friday the 14th. The morning is still a struggle, but the afternoon shows a flicker of life. We see the swell nudge up to 3ft from the SSW with a long period of 18 seconds, and the combined energy jumps to 717 (moderate). It’s still described as marginal, with that cross-onshore wind, so don’t get too excited. It’s a "maybe" session for the die-hards.

Saturday the 15th is the closest thing we’ve got to a highlight. Morning has 3ft SSW swell at 16 seconds, and the wind is light and onshore (WSW). The combined energy is a solid 613. Afternoon looks a little better with the swell hitting 4ft from the SSW and the energy up to 666, still with light onshore winds. It’s still marginal, but this is the best on offer – the only time we get over three feet. The water temp is a very unusual 77°F (about 9°F above normal for this time of year), so you won’t need a thick suit. This is a beach/jetty setup, so that long-period swell (over 15 seconds) might break a bit straight, but with those light winds, it could be worth a look for the experienced crew. The crowds are often there, so expect company.

After that, we slide back into the doldrums. Sunday the 16th and Monday the 17th are back to poor conditions with 3ft swell and light onshore winds. Tuesday the 18th and Wednesday the 19th stay small and weak, with the afternoon of the 19th being the last marginal call (score of 1) before Thursday the 20th wraps it all up with more poor, choppy 2ft slop.

In short, the first ten days are a total loss. If you’re desperate, the afternoon of Friday the 14th is a maybe, but Saturday the 15th is your one true stand-out. It’s not going to be epic, but with the water that warm and a little bit of energy, you could snag a couple. Don’t hold your breath for the rest of it.

Stay patient,
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.
