The Lowdown
Alright, folks, Rusty here. Let's have a look at what’s on offer for the next couple of weeks.
Honestly, it’s a tough start. We’re looking down the barrel of a long, flat, and choppy stretch. There’s nothing worth paddling out for from now right through to the end of the first week. The wind is howling out of the north, and the swell is mostly short-period, messy northwesterly junk under 4ft. The wave energy is weak, nowhere near enough to push anything decent through. A gap of several days with no real surf to speak of.
The one and only bright spot in this whole forecast, and it’s a true standout, is the morning of Wednesday, the 16th of September. This is the one to circle on your calendar. The conditions suddenly flip. The wind drops to a dead glass, 3 mph, and the swell cleans right up. We’re looking at a solid 5ft groundswell from the NW, with a very long 13-second period, packing serious grunt – the energy reading shoots up to 1445. That’s a heft of water moving. Now, with that kind of period at a beach break like Baleal Sul, it does have a tendency to throw fast, sometimes linking up down the line too straight. It’ll be best suited for a longboard or a fish and working the inside sections, but if you’re an experienced surfer, the clean conditions will make it a proper session. With a score like that, and the water feeling about average for the time of year, this is the day.
Everything else in the 16-day window is pretty grim. There are a few moments on the 6th and 10th of September where a cross-offshore wind and a pulse of moderate energy (373 and 334) pop up, but they’re swamped by the sheer volume of onshore slop. Don’t waste your energy on those.
Bottom line: Wait for the 16th. That one morning looks like the only window of proper, lined-up surf. It’s a long way off, but worth the patience.
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. 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.
