The Lowdown
Alright, Rusty here. Let’s talk about your local patch.
Honestly mate, it’s a bit of a grim stretch ahead for Baleal Sul. Most of the time the wind is either onshore or cross-onshore, and the combined wave energy (707) on day one tells you we’ve got mediocre swell. The water is sitting at 67° with a temperature anomaly of -1°, so it’s a bit colder than normal for this time of year — definitely not a warm tropical bath.
Starting on Friday the 21st (morning), we’ve got waist-high 4ft swell from the NNW at 11 seconds, but a stiff 19 mph north wind is blowing straight onshore. It’s messy, poor surf — skip it. That afternoon the swell bumps up to 7ft but the NNW wind’s still onshore, so no good.
Saturday the 22nd stays poor. Morning has 5ft with a cross-onshore WNW breeze, making for lumpy, unappealing conditions. Afternoon drops to 4ft and a cross-shore WSW breeze, so it’s small and chopped — nothing worth paddling out for.
Sunday the 23rd, morning shows 6ft swell from the W with a long 11 second period and a brisk SSE offshore wind at 16 mph. The wind is clean and offshore, and there’s moderate wave energy (821). This is the standout window for the whole outlook. The wave comment is marginal, but the conditions are the cleanest you’ll see all week. It’s inconsistent here and it’s a sheltered beginner break, so don’t expect perfect walls, but if you want to get wet with decent chop-hop, that morning session is the best on offer. The afternoon gets some heavy rain but still clean offshore winds from the south, with 5ft and moderate energy (452) — it’s surfable, just watch for the rain.
Monday the 24th goes downhill fast. Morning has 7ft from the SW but wind is 22 mph from the south and cross-offshore. That swell is short period (8 seconds), and combined energy (557) is moderate, not super powerful. Still, the raw size and choppy wind make it rough. Afternoon is worse with 8ft and a strong cross-shore blow. Not for beginners.
Tuesday the 25th drops off hard. Morning: 4ft from the west with a 6 second period — tiny and weak (115). Afternoon is just 3ft. Barely a ripple. Wednesday the 26th is similar — 4ft and cross-onshore.
Thursday the 27th sees size return with 7ft from the WNW, but again cross-onshore wind (12 mph) and combined energy (592) doesn’t save the day. Choppy, messy, poor surf. Not recommended.
Friday the 28th has 7ft NNW swell with a longer 10 second period, but onshore NNE then NNW winds ruin it. After that it’s a whole string of onshore winds and mediocre to poor conditions. Saturday the 29th to Sunday the 30th stays below 7ft, but the wind direction keeps it messy.
The one bright spot much later: Thursday the 3rd of September. The morning shows 5ft from the NNW with a long 11 second period and an onshore breeze, but the energy jumps to 847. By the afternoon we get 7ft from the NNW at a very long 12 seconds — combined energy hits 1122 (strong). That’s the biggest, most powerful swell of the forecast. Wind is onshore though, and because it’s long period groundswell, Baleal Sul being a sheltered spot won’t handle it well. It will close out or be too straight. Still, if you’re an experienced surfer and you don’t mind some chop, that afternoon holds promise. But it’s a long way off, so don’t bank on it.
After that we fade out again into early September with tiny weak pulses and onshore wind.
Overall, if there’s one session to pencil in it’s Sunday morning the 23rd — clean offshore, 6ft, moderate energy. The rest is a write-off for most of us. No standouts worth cancelling your day for.
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. 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.
