Table - best surf conditions forecast for Oceanside Harbor over the next 16 days.
Alright folks, Rusty here with a look at the next few weeks. I've got the scoop on what's happening at Oceanside Harbor, and I gotta be straight with you – it's gonna take some patience.
We’re starting off with a real flat spell. From now through Saturday, July 20th, it’s pretty grim. The surf is barely there, with small to tiny swells and mostly messy, onshore winds or poor cross-onshore conditions. Energy is weak, all under 500 (moderate) and most days are below that. You’d be wrestling with chop and dribblers. Honestly, for the first week plus, you're better off doing something else.
Now, hold onto your leash. There's a flicker of hope. On Sunday morning, July 25th, we see a bump in size to around 5ft from the S, but the wind is cross-onshore, which will put a bit of a crumble on it. The energy jumps up to 841, but the quality is still just marginal.
The real standout, the one that’s got my heart beating a little faster, is looking at Sunday the 25th. Swell is 5ft from the S with a period of 13 seconds. That’s a nice groundswell. The wind is a light cross-onshore, which isn't perfect but it's manageable. The break is a beach/jetty setup, so that long period (over 11 seconds) might make it a bit straight, but with that size and the energy reading at 841, it could produce some decent walls. It’s a long way out, so treat it as a promising possibility, not a guarantee, but it’s the best thing on the table.
Before that, the morning of Saturday, July 19th has a 4ft S swell, but it’s pretty weak and no better than marginal.
Overall, it's a bleak start. But that last weekend in July has a bit of a pulse. Keep your eyes on the charts, and check back with me.
Stay frothing.
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.

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.
