The Lowdown
Alright, grab your wettie and listen up. It's Rusty here. We've got a bit of a mixed bag on the horizon for our stretch of coast, so let's break it down day by day.
The immediate future, starting today the 11th, is pretty lackluster. We've got some small, weak swell pushing in from the ENE, maybe 3ft at Estaleiro Reef (Rio Grande do Sul), with a short period. There's a light cross-offshore breeze that should keep things clean, but honestly, it's pretty average. We're looking at an energy reading of just 111, which is weak. Friday afternoon will be even smaller.
The weekend is a write-off. From Saturday the 12th through to Monday the 14th, an onshore flow kicks in from the SSE and SE, with increasing speeds. The swell will be here, but it's going to be a choppy, messy, onshore mess, with the wave energy building from a moderate 138 to a strong-ish 467 by Monday afternoon. The water temp is 66°, which is pretty much average for this time of year, so no surprises there.
Alright, now this is where things get interesting. Springing into Tuesday the 15th, we've got a whole different feel in the air. A light SW wind will groom a cleaner, stronger E swell. The swell height is pushing to 6ft with a better 9-second period and the energy is climbing to 591. This is easily one of the best windows we get. It still might be a bit raw for beginners at 6ft, but for the intermediates, early morning looks like the call for the cleanest conditions at Estaleiro Reef.
Wednesday the 16th sees the onshore winds return and things go a little ragged again. It's not big and it will be lumpy. We'll see a bump in energy on Thursday the 17th from a longer period SE swell, but the onshore wind ruins any real potential. A bit of surfable, ordinary stuff is on the cards for Friday the 18th, with a tiny, glassy bump in the afternoon.
The following week holds a tantalizing prospect but with a long wait. After a few more small, average days, things are going to go off around Wednesday the 23rd of September. A serious S swell is forecast to hit, with a wave height of 8ft and a strong energy reading of 1739. The wind direction looks favorable – WSW, which should be offshore. But, and this is a big but, that size is too big for Estaleiro Reef, and the text specificaly notes that the swell is predicted to be too big for this break. That's an experts-only scenario there, and even then, it might be too much for the setup.
The final standout comes the very next morning, Thursday the 24th. The swell eases a bit to 5ft but the period stretches out to a solid 12 seconds. With a light offshore W wind and an energy reading of 829, this is looking like the pick of the entire fortnight. Clean, lined-up and with a bit more push, this is the condition Estaleiro Reef will love.
The last few days of the window fade out to small, clean leftovers on Friday and Saturday the 25th and 26th, but by then, we'll be looking at next week's charts.
So, to keep it simple: the surf this weekend will be poor, and you'd be wasting your time. Your two true standouts are Tuesday morning, the 15th, for a clean, mid-size swell, and the real gem looks to be the morning of Thursday, the 24th, when the stars align with a solid, long-period groundswell and light offshore winds.
Signing off.

Information about the Estaleiro Reef Surf forecast
The above surf forecast table for Estaleiro Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Estaleiro Reef can be found by selecting the local surf guide option on the grey menu. Our Estaleiro Reef 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 (Estaleiro Reef) 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 Estaleiro Reef 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.
