The Lowdown
Alright, Rusty here. Let’s get into what we’ve got coming up.
The first week is a tough one. From Saturday September 12th right through to Monday the 14th, it’s all poor. Onshore wind, choppy mess – don’t bother paddling out. The water is sitting at 66°, right around average for the time of year, nothing wild there.
We finally get a window on Tuesday September 15th. Early morning at Estaleiro Reef, we see a 5ft East swell with light cross-offshore wind – clean conditions. The combined energy is moderate at 358, and the surface should be smooth. It’s not pumping, but it’s the first real chance to get wet after a few rough days.
The days after are mostly small and messy. But we get a couple of clean windows Friday September 18th and Saturday September 19th with swell around 2ft, light offshore winds, and clean faces. It's small stuff, knee-high at best, so only worth it if you’re itching for a session.
Now, the big one. Thursday September 24th is the standout. Estaleiro Reef gets a solid 6ft swell from the SE with a very long period of 17 seconds – that’s proper groundswell, powerful and well-organized. Combined energy is massive at 2171, so there’s a ton of water moving. Wind is NW at 6 mph, nicely cross-offshore, keeping the surface clean. This one is for experienced surfers only – over 5ft, so beginners need to sit this one out. That long period means it’ll handle best at the reef, with long lulls between sets and plenty of power.
Friday September 25th is still a good session. Morning delivers a 5ft SE swell at 16 seconds, still a long-period groundswell, with clean cross-off winds again. Combined energy is strong at 1024. It’s a step down from Thursday but still a solid day for those with the skill.
The weekend of the 26th and 27th fades back into smaller, less interesting conditions with a brief clean window on Saturday morning, then onshore winds messing it up again.
Bottom line: you’ll wait through a lot of sloppy days, but that Thursday the 24th is the real deal. Otherwise, bring a longboard and patience.
Rusty.

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.
