The Lowdown

Alright, folks, Rusty here with a look at Oceanside Harbor.

It’s gonna be a lean couple of weeks, no two ways about it. We’ve got a lot of small, weak swell rolling in with mostly cross-onshore winds. The water’s sitting at 74°, which is a good three degrees warmer than usual—you’ll be fine in boardies or a very thin wetsuit.

The wave energy is mostly moderate, in the 241 to 655 range. It’s not dead flat, but it’s not alive either. Swell direction is locked in from the southwest, which is right for this spot, but the size just isn't there. We're looking at 2ft to 3ft for most of the period.

Starting Monday the 14th and Tuesday the 15th, it’s pretty sad. Tiny 2ft to 2ft of SW swell with light cross-onshore breezes. The water is warm, but the surf is just messy and weak.

Things pick up a touch from Wednesday the 16th through the 20th. The swell bumps up to 3ft to 3ft, still from the southwest. The period is long, in the 16 to 18 second range, so there’s some push, but not enough size. Wind stays light and cross-onshore. You might get a few crumbly ones if you’re patient, but it’s not going to be memorable. The energy climbs into the 400-650 range, so there’s something there, but it's not making it to the beach.

For the best of a bad bunch, I’d point to Saturday the 19th and Sunday the 20th. The swell is holding around 3ft to 3ft from the SW with those long 18-second intervals. The energy is the highest we see, hitting 555 on Sunday morning. Still, it’s not big. Winds are light onshore, so it won’t be glassy, but it won’t be blown out either. At Oceanside Harbor, with this swell direction, you’ll want to hunt for the peaks.

From Monday the 21st through the end of the window on Tuesday the 29th, it’s a slow fade. The swell stays small, dropping back to 2ft to 3ft, with the period shrinking from 17 seconds down to 13 seconds by the end. The wind picks up a bit, especially on Sunday the 27th with a moderate W wind making it choppy. After the 22nd, the energy drops below 500 and it just becomes a wall of whitewater. By the 24th through the 29th, the period drops below 15 seconds, which means less push and more chop. It’s going to be a frustrating stretch.

Honestly, there are no big days here. No one’s canceling plans for this. The standout, if you can call it that, is the morning of the 20th with that 3ft SW swell and 18-second period. It’s the most organized it’s going to be, but it’s not for beginners. This is all about getting a few fun ones in, not chasing anything epic.

So, there you have it. A lot of small, weak surf. If you’re just jonesing for a paddle, you might find something, but keep the expectations low. This is a stretch where the ocean is mostly saying “not today.”

Rusty out.

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.
