The Lowdown
G’day, Rusty here, and I’ve got the outlook for Baleal Sul. This sheltered beginner wave is in for a rough couple of weeks – mostly ordinary with a few moments that might get your hopes up. There’s a long quiet patch in the middle where it’s just blown-out junk, so let’s get into it.
Tuesday the 18th kicks off with a clean 5-foot swell from the NNW at 8 seconds, but it’s cross-off with a 9 mph southerly breeze – surfable, but very ordinary. That afternoon, the wind jumps to 19 mph from the SW and the swell drops a bit, but it’s still a cross-off, so nothing special. Wednesday the 19th morning is a 3-foot, 7-second NW windswell with a light WSW cross-off – weak energy, but it’s clean and rideable for the absolute beginner. That afternoon gets messy with a cross-shore breeze.
Thursday the 20th is the real tease. A glassy morning with 2-foot waves from the WNW, period 9 seconds – it’s barely a ripple and weak as anything. Perfect conditions if there was any swell, but there isn’t. Then from Friday the 21st right through to the end of August, it’s a wall of onshore wind and growing swell that’s just ugly. Friday morning sees 6-foot from the NNW at 7 seconds with a 19 mph northerly onshore, moderate energy but blown to bits. Saturday the 22nd and Sunday the 23rd are worse – up to 8-foot on Sunday, 8-second period, and a 22 mph northerly onshore. That size is too big for beginners anyway, and with that wind, it’s just a washing machine. Monday the 24th through Tuesday the 27th stays onshore with solid wind – between 4-foot and 7-foot, all poor. From Thursday the 28th, the swell gets sloppy and short-period again. There’s a 5-day gap here where there’s honestly nothing worth paddling out for.
Now, if you’re looking for the one standout, it’s Saturday the 29th morning. The wind swings WSW at just 3 mph – a light cross-shore – and the swell picks up to 5-foot from the NNW at 10 seconds. That longer period means more energy and better shape, with moderate energy. It’s clean, the tide might be a factor but it’s the best looking window in the whole run. That morning is the one to target. Sunday the 30th morning also has potential – 8-foot from the NNW at 8 seconds, cross-off wind from the SW at 12 mph. That’s big for this spot though, and at 8-foot on the afternoon it’s expert territory only, so if you’re not solid, give it a miss.
Overall mate, this is a lean stretch. The first few days have tiny, clean waves for a learner, then a long blowout, then a couple of decent windows right at the end of August and start of September. Keep an eye on that Saturday the 29th – it’s the best of a tricky bunch. Stay stoked.

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.

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.
