The Lowdown
Alright, Rusty here. Let's get into it.
It's been a pretty quiet run at Baleal Sul lately, and the first week of this outlook is largely a write-off. There will be a solid gap of several days with nothing worth paddling out for until we see some quality on Sunday the 13th.
That Sunday morning (13th September) is our first real standout. The wind is glassy, dead calm, which is a massive plus. We've got a 3.9ft groundswell from the NW with a long period of 13 seconds, and the wave energy is ramping up to a moderate 466. The water is sitting at 63.9°, but that’s a massive 4.7° colder than normal for this time of year—a real shock to the system, so you’ll want a 4/3, maybe booties. This is the best on offer for the near term.
Monday morning (14th) offers a quick flash of clean, glassy conditions with a smaller 3.0ft NW swell (period 11s, energy 281), but it’s not the standout. The next real window doesn't open up until Wednesday morning the 23rd of September when we get another glassy morning. That brings a 4.6ft NW swell at 11 seconds, with a 477 energy reading. It's a decent option.
Now, looking way ahead, Friday the 25th of September morning looks like the real big one, but it’s a long-range call. The guidance is pointing to a strong 8.2ft NW groundswell (14-second period), and the combined energy is a massive 3018, which is very strong. Because that's a long-period swell on a beach-and-reef setup, it could be a bit straight and tricky but there will be plenty of power. The wind is light and cross-off, keeping it clean. That one is for the experienced crew only.
Crowds at Baleal Sul can be a thing sometimes, so get in early for the clean windows.

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.
