The Lowdown

Alright folks, Rusty here. Let's take a look at what's cookin' for our local stretch. Gotta be honest with ya, this one's a bit of a slow burn.

The first decent wave we see is gonna be on Monday, August 14th, with a tiny bit of life showing through the afternoon. Don't get your hopes up for anything special, though. The water temp is sitting at 76°F which is a whopping 9°F warmer than normal for this time of year. Feels like a bath out there, which is weird but not un-welcomed.

The real standout, and the only real action to get excited about, is that Monday afternoon, August 14th, at Oceanside Harbor. The swell is coming from the SSW at 2ft with a super long period of 18 seconds. That's a proper groundswell, meaning those waves are gonna have some serious push and shape. The energy is strong too, hitting 501 (strong wave energy). The wind is light, coming from the SW at 6 mph, and it's directly onshore, so it won't be glassy, but it's light enough to be manageable. This is an advanced break, so it's not for the groms—that 2ft on a long period will be a bit more powerful than it looks.

The next morning, Tuesday, August 15th, has a similar but weaker setup with 3ft from the SSW at 16 seconds, but the wind is a bit better, light and onshore. The energy is even higher at 592 (strong wave energy), but the forecast says it's a marginal one. It's probably going to be a bit of a bumpy ride.

After that, it's a whole lot of "meh" for days. We get a bit of a reprieve on the afternoon of Monday, August 17th, when the wind shifts to a light cross-offshore from the NNW at 6 mph, making things clean. But the swell is small at 2ft from the SSW. It's a wave, but it's not a great one.

Then we hit a new problem. On Tuesday, August 18th, the swell jumps to 4ft but from the west, with a short, weak period of just 8 seconds. That's a windswell, and it's gonna be a bumpy, choppy mess. The wind is 9 mph cross-on from the west, so expect a messy, blown-out scene. The next afternoon is even worse, with 12 mph cross-on winds.

So, here's the bottom line: the best bet is that Monday afternoon, August 14th, at Oceanside Harbor. It's the only window with a decent, long-period swell and light winds. After that, it's a long stretch of poor conditions. The short period stuff on the 18th is not worth paddling out for unless you're a kite surfer—that's a more interesting setup for the wind.

Stay patient, and keep an eye on the forecast. Things can change, but right now, it's a waiting game.

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.
