The Lowdown
G’day, Rusty here. Look, I’m gonna be straight with you – this stretch for Baleal Sul is a tough watch. The whole 16-day window is basically one long run of ordinary to poor surf. The combined swell energy is mostly moderate, sitting between 122 and 1380, but the quality just isn’t there. You’ll see a few tiny windows where it’s *almost* worth paddling out, but nothing you’d call a standout. The water temperature is 67°, and at about a degree and a half Fahrenheit colder than usual for this time of year, it’s a bit nippier than you’d expect.
The only chance that gets even close to something you’d point your board at is Tuesday morning, 25 August. We’ve got a 8 ft swell wrapping in from the NNW, with a clean, light cross-off breeze from the ESE at 6 mph. That cross-off wind should keep the faces tidy. Combined energy is 661 – solid moderate juice. But it’s inconsistent here, and the swell period is only 8 seconds, so it’s a short-period wind swell, not a proper groundswell. It’s a beginner break, and honestly, even that session is a 2 out of 10 kind of deal – surfable, but nothing to write home about.
Other than that one morning, you’re looking at onshore winds, strong breezes, and a whole lot of “poor surf conditions” labels. Through the first week and into the second, there are days with 8 ft and even 10 ft swell, but it’s all being hammered by onshore NNW wind at 12–19 mph. That’s messy, blown-out slop. The longer-period swell (10 seconds) that pops up around 22–23 August is more interesting in theory, but again, the wind ruins it.
The last week is more of the same – a few mornings with glassy or offshore wind, like Thursday morning, 27 August, with 5 ft swell and glassy conditions from the SSE at 3 mph, but the combined energy is low at 235 and the period is short (7 seconds). It’s rideable but very ordinary.
Bottom line: there’s one half-decent morning on 25 August for a beginner paddle, but the rest is a write-off. If the wind switches, things could change, but right now, I’d save the wax.
Rusty.

Information about the Baleal Sul Surf forecast
The above surf forecast table for Baleal Sul provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Baleal Sul can be found by selecting the local surf guide option on the grey menu. Our Baleal Sul 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 (Baleal Sul) 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 Baleal Sul 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.
