The Lowdown

Alright, grab a coffee and settle in, because it’s a bit of a mixed bag for Oceanside Harbor over the next couple of weeks. I’m Rusty, and I’ve been staring at this stretch of coast long enough to know when to get excited and when to take a nap.

First up, the water temperature is cranking at 72°, which is a solid 5° warmer than usual for this time of year. That’s a big deal – you’ll be comfortable in a spring suit or even just a rash guard in the afternoons.

The forecast starts with a real flat spell. Friday the 17th through Sunday the 19th are basically a write-off. You’re looking at knee-high slop with cross-onshore winds messing it up. The combined swell energy is weak (298), and it’s just not worth paddling out for. It’s a good weekend to fix your dings or go for a fish.

Things start to look a little more interesting around Monday the 20th. The swell picks up a bit, hitting 6 ft from the SSW, but the wind is still cross-onshore, so it’s going to be a bumpy, choppy mess. The energy is getting stronger (898), but the quality isn’t there. Not the one.

The standout of the whole run actually comes later. Look at Saturday the 25th and Sunday the 26th. We’ve got a sweet 5 ft SSW swell rolling in, and the wind is swinging light, offshore from the SW. That’s the magic combo: clean, glassy conditions. The swell period is a solid 14 seconds, so there’s proper groundswell power behind it, and the energy is pumping (1388). This is the best on offer – a proper window of clean surf. The south swell is hitting the jetty nicely, and with light offshore wind, it’ll be lined up and rippable.

After that, Monday the 27th and Tuesday the 28th keep the energy going with 4 ft to 4 ft SSW swell, still with offshore winds. The combined energy is strong (1507 on Monday afternoon), so the wave power is there. But by the following week, the swell starts to fade and the wind gets a bit cross-onshore again, so it’s only worth it if you’re desperate for a paddle.

The last week of the month and into August is mostly small and weak. From Thursday the 30th onward, the energy drops below 500, and the wind is back to cross-onshore. It’s a real fade-out. If you’re a beginner, the 4 ft days are just about manageable, but anything over 5 ft (like Monday the 20th) might be a bit much if you’re just starting out. For the experts, the 6 ft day on the 20th is the biggest, but it’s messy.

The real pick is Saturday the 25th and Sunday the 26th. Clean, waist-to-chest high, glassy, and with that long-period groundswell wrapping in. Those are the days to clear your schedule.

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.
