Alright folks, Rusty here. Let's have a look at what's on the cards for Oceanside Harbor over the next couple of weeks.
Right off the bat, it's a bit of a slow grind. The water temp is sitting at 69°, which is a touch warmer than normal for this time of year, so at least you won't be needing a thick suit.
The first few days are looking pretty grim. We've got a long-period groundswell from the SSW, but it's tiny, around 3ft, and the wind is all wrong. It's cross-on and choppy, and the wave energy is just moderate at best in the 400-700 range. Honestly, Wednesday the 8th through to the morning of Saturday the 12th is a write-off. The surf is just too small and messy to bother with. There's a real gap here with nothing worth paddling out for.
We start to see a glimmer of hope around Sunday the 19th. The swell picks up a bit, but the real story is the energy. On the morning of the 19th, the combined energy jumps to 1051 (moderate), and by the afternoon it's pumping at 1484. That's a serious bump in energy. The swell is 4ft from the S with a 15-second period, which is a nice long period groundswell. The wind is light and onshore, so it'll be a bit bumpy, but the power is there.
Then, Monday the 20th morning is the stand-out. The swell hits 6ft from the S with a consistent 14-second period. The combined energy is 1246. Now, 6ft is getting into the intermediate-to-advanced territory, but it's not a complete monster. The wind is WSW at 9 mph, which is onshore, keeping it a bit raw. Still, this is the biggest, most powerful swell of the whole outlook. For the experienced crew, this is the best on offer. The swell direction (S) is a touch off the Harbour's optimum W, but the size and period make up for it.
The rest of the second week drops off quickly. By Tuesday the 21st, we're back to small, weak, cross-on junk. Nothing to get excited about. So, the one true standout is that window from the afternoon of the 19th through the morning of the 20th. Don't hold your breath for anything before that.
Rusty, signing off.

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.
