The Lowdown
Alright folks, Rusty here. Let’s take a good hard look at what Oceanside Harbor has in store for us over the next couple of weeks. Don’t get too excited just yet – the first week or so is looking pretty flat and messy.
We’ve got a long stretch of small, weak surf on the way. For the first week, from Tuesday the 14th right through to Monday the 20th, the waves are tiny – mostly around 1ft to 4ft – and the wind is a problem. It’s coming from the west and southwest, mostly cross-onshore, making things choppy and unappealing. The combined swell energy (269) to (875) tells you it’s just not packing any punch. You’ll see scores of zero and ones in that period. Honestly, for a beach/jetty break like Oceanside Harbor, it’s a write-off. The water temp is about average for July, so that’s one thing going for us.
Now, things start to get a little more interesting from the morning of Tuesday 22nd July. We finally see a pulse of solid south swell pushing through. The swell builds to 5ft on Wednesday morning, 5ft in the afternoon, and the combined energy jumps to (1392) to (1507), which is a moderate push. The period is a decent 15 to 16 seconds, so it’s proper groundswell with some shape.
The standout day looks to be Thursday the 23rd of July. We’ve got the biggest swell of the run so far: 7ft on the morning and 7ft in the afternoon from the south, with a 14 to 15 second period. The combined energy hits (1871) to (2116) – that’s a solid, strong pulse. The wind is light from the WSW, cross-onshore but with only a light breeze, so it’ll be clean. This is a decent window for experienced surfers. At 7ft, that’s getting too meaty for beginners at a beach/jetty spot. The Saturday morning the 25th also has 7ft from the SSW with the same light cross-onshore wind, another good option. Keep in mind, the long period south swell will tend to wrap in and close out on the beach, but the jetty there can offer a better line.
After that Friday the 24th and Saturday the 25th, the swell drops back down quickly. By Sunday the 26th, we’re back to 3ft and smaller for the rest of the outlook through the 29th. The energy fades (1235 down to 472) and the poor surf conditions return. The waiting game continues.
So, the pick of the period is Thursday 23rd and Saturday 25th July. That’s where you want to be in the water. Remember, short-term calls are more reliable; the long-range stuff is promising but less certain.
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.
