Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Oceanside Harbor. I gotta be straight with you – this stretch doesn’t have much on offer for a proper paddle session. The whole 16-day window is pretty grim, with the first real chance of anything ridable showing up on Monday, July 6th.
The setup is a beach/jetty spot, wide open to the west swell, and we’ve got a long-period SSW groundswell trying to push in. That period is nice and long, hitting 16 seconds and sometimes 18, which means more energy in the water and those long lulls between sets. It’s the kind of swell that loves a point or a reef, so at a beach setup like this, it might break a bit too straight at times. The water is sitting at 69°F for the first break I’m looking at, which is a touch warmer than normal for this time of year – that’s a small plus.
Now, the saving grace, if you can call it that, comes in the middle of the second week. On Tuesday, July 14th, the morning session is the one that’s flagged as worth a look. We’ve got tiny swell, only 2ft from the SSW, but the real story is the wind. It’s glassy. Dead calm. That is a major positive in a forecast full of cross-onshore chop. The combined energy is weak at 189, so it’s not gonna have any push, but for a quick log session or a longboard glide, it’ll be clean as a whistle. That’s your only standout in this whole run, but keep your expectations low.
The rest of the time? Mostly “poor surf conditions” is the name of the game. From now through July 3rd right up to July 6th morning, it’s a bust. Monday afternoon, July 6th, the energy jumps up to 609 (moderate), and we get 3ft, but the wind is a light cross-onshore. It’s still just “marginal.” Tuesday and Wednesday of that first week have the biggest combined energy we see, with 812 and 875 (strong), and swell sizes around 3ft to 4ft, but again the wind is cross-onshore or onshore – never really clean.
After that July 14th glassy morning, it drops back into poor conditions for the rest of the run. Honestly, with the persistent cross-onshore wind and the swell often being small and wind-affected, this setup looks more interesting for kite surfing than paddle surfing on most of these days.
So, to sum up: if you absolutely have to get wet, mark Tuesday morning, July 14th, for a glassy, small-wave session. But don't expect anything with any power.

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.
