The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Oceanside Harbor.
First thing you gotta know: the water is absolutely cooking right now. We’re talking 75°, which is a whopping 8° warmer than usual for this time of year. That’s very unusual, so don’t bother with the thick wetsuit.
The pattern for the next 16 days is a bit of a mixed bag. We’ve got some solid swell energy rolling in, but the wind and the quality of the surf are the real issues. The best bet for a proper session looks like Monday the 27th and Tuesday the 28th. That’s where the combined energy really jumps up, peaking at 1315 on Tuesday morning, which is strong wave energy. The swell is hanging around 4ft to 5ft from the SSW, with a 17 to 18-second period. That’s a long-period groundswell, which means proper push and shape, but it can be a bit crumbly at a beach/jetty setup. The good news is the wind is light and onshore, but it’s light, so it’s not going to trash it completely. The morning of Tuesday the 28th is the standout for me – 5ft of SSW swell, that 17-second period, and light onshore winds. It’s a solid option for the advanced crew. Expect crowds to be a factor here, as it’s a very consistent spot.
After that, it tails off. The energy drops significantly through the end of July and into August. By the time we get to August 4th, the swell is down to 1ft with weak energy, and the quality is poor. The winds get a bit more cross-onshore, making it choppy. There’s a long gap of poor conditions from the 30th of July right through until the 6th of August. There’s not much to get excited about there.
So, to sum it up: get on it Monday the 27th and Tuesday the 28th. That’s your window. After that, it’s a waiting game.
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. 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.
