Table - best surf conditions forecast for Oceanside Harbor over the next 16 days.
Alright, Rusty here again. Let’s break down Oceanside Harbor.
For the here and now, through the middle of the month, it’s a quiet spell. Onshore and cross-onshore winds are hanging around, and the waves are tiny, mostly 1 to 3 feet out of the SSW or SW. The combined energy is on the weak to moderate side. Water temp is about 70°, which is a touch warmer than average. The surf quality is described as poor or marginal. With the wind and small size, the jetty and beach setup might honestly be more fun for kite surfing than trying to catch these bumpy little lines. We’ve got a dry spell of nearly two weeks without any standout action.
But there’s hope. The best window pops up on Saturday, July 25th. That day sees a solid uptick in size – waves around 6 to 6 feet from the south, with a moderate period of 15-16 seconds. The combined energy jumps strong, hitting that 1490 mark – the best energy of the entire outlook. Winds look a bit more manageable, with onshore and cross-onshore but lighter breezes. It won’t be glassy, but there’s real power behind these waves. This is the one to watch. At 6 to 6 feet, it’s better for experienced surfers, bordering on expert territory. This is a week and a half out, so it’s promising but not a sure thing.
In short: nothing good for the next week-plus. Circle July 25th if you want a chance at some real waves.
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.

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.
