The Lowdown
Alright folks, Rusty here. Let's take a good hard look at what Baleal Sul has in store for us over the coming days. Gotta be straight with you, this forecast is a bit of a rough one. Nearly the entire 16-day window is filled with "poor surf conditions" thanks to windy, onshore, or cross-onshore breezes that just won't quit. The swell hangs around but the quality is just not there.
For the first week and a half, from Friday the 28th of August right through to the afternoon of Thursday the 10th of September, you're mostly looking at onshore and cross-onshore winds from the north and northwest. Morning sessions on the 31st of August and the 1st of September see wind speeds up to 19 mph, which will make things rough. There's a bit of a bump around the 2nd of September with swell heights hitting 7 ft, but that's accompanied by a short 8-second period and moderate cross-onshore winds, so it's messy. The combined wave energy gets up into the moderate range then, but the onshore wind just kills it. There's a sniff of a glassy moment on the morning of Saturday the 5th of September, with only 3 ft of swell and a 3 mph glassy breeze, but that swell is tiny and short-period. That's about as good as it gets for a while, and I'm calling it "surfable but ordinary".
The only real stand-out – and I mean the *only* one worth getting a little excited about – arrives on the morning of Sunday the 6th of September. We see a jump in swell height to 4 ft with a much longer period of 13 seconds, and a light onshore breeze from the NNW. The combined energy is solid, and that longer period means it won't be as choppy. It's still onshore, but the light wind and long-period groundswell should offer some cleaner, more lined-up sets. The afternoon of the 10th of September also shows some promise with a 7 ft, 12-second swell from the NNW and light cross-onshore breezes, putting the energy way up there. That's a decent push, but it's still a bit cross-onshore. For a beginner break like Baleal Sul, you're looking for that glassy, clean window, and outside of that Saturday morning the 5th, it's mostly a battle with the wind.
Water temp is sitting at 67°F, which is about normal for this time of year.
After the 10th, the swell drops right off, and we're stuck with small, wind-affected leftovers through to the 12th of September. There's just not much to recommend.
This is Rusty, signing off. Keep an eye on the sky, but don’t hold your breath.

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.
