The Lowdown

Alright, Rusty here. Let’s have a look at the stretch ahead for Baleal Sul.

Honestly, I gotta be straight with you – the next 16 days are a tough one for Baleal Sul. The surf is there, but the conditions are just not cooperating. The wind is a persistent problem, and it’s almost always onshore or cross-shore, messing up what could be decent waves. The water is a bit colder than normal for this time of year, sitting at 66°, which is a noticeable chill.

We start with a bit of a gap, but Tuesday the 25th sees a small 4ft swell from the WNW with a short 7-second period. The combined swell energy is weak (168). It’s surfable, but with a light cross-offshore breeze, it’s just very ordinary. The afternoon drops off. Wednesday the 26th gets worse with a fresh 19 mph cross-offshore breeze and a messy 4ft swell. The pattern is grim: Thursday the 27th has a 7ft W swell (538 energy) but it’s crossed up and choppy. Friday the 28th brings a bigger 8ft WNW groundswell (1350 energy – moderate energy), but that’s with a cross-onshore wind and a 11-second period. That long period means it’s better suited for a point or reef, but Baleal Sul is sheltered and the wind is blowing right across it.

The whole first week is a write-off for good surfing. The wind stays onshore or cross-onshore from the north, with gusts up to 19 mph. Even when the swell size is decent, the quality is poor. From the 29th of August through the 4th of September, we’re looking at a solid run of onshore winds from the north, with swell heights bouncing between 3ft and 7ft, but always with a chop. The energy stays moderate (200-500 range), but it’s not worth paddling out for.

The only real standout in this whole period comes on Monday the 7th of September. We’ve got a 8ft swell from the NNW with a very long 12-second period, and the combined energy is strong (1839). That’s a lot of power. But again, the wind is a cross-onshore from the NNE at 16 mph. For a sheltered spot like Baleal Sul, that’s a big problem. The waves will be big and powerful, but the wind is going to chop them up and make it a real fight. It’s expert territory, and honestly, for most, it’s more of a kite-surfing setup than a paddle session. The afternoon stays onshore and messy.

The 8th of September has a weird one – a 4ft swell with a massive 16-second period and moderate energy (1144), but it’s straight out of the NW and with a 19 mph cross-onshore wind. That long period will make it break too straight and the wind will ruin it. The 9th is more of the same.

Honestly, there’s no day here I’d call a “good” surf. The wind is the enemy for the entire 16-day window. It’s a blank run, and it’s not unusual for this area when the trades get locked in. The swell is there, but the quality isn’t. Keep an eye on the forecasts, because it tends not to stay this poor for long, but for now, I’d leave the board at home.

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.

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.
