The Lowdown
G’day, Rusty here. Let’s see what’s shaking over the next couple of weeks.
We start off slow. Monday the 31st of August has tiny surfable waves at Estaleiro Reef, but nothing to write home about. The swell is only 3ft from the ENE with a short 8-second period, and the combined energy is weak at 142. The water temp is about 68°, which is pretty average for this time of year. Monday afternoon turns glassy, but the waves are still puny.
Tuesday the 1st of September stays clean in the morning, but the swell is still small. By the afternoon, the wind goes onshore at 25 km/h, making it choppy and ugly.
Then we get a proper standout. Wednesday morning the 2nd of September is the one to circle. The swell jumps to 6ft from the SE with an 8-second period, and the combined energy is moderate at 656. The wind is light and cross-offshore from the SW at 6 km/h, so the waves will be clean and well-shaped. This reef break is inconsistent and sometimes crowded, but on a Wednesday morning you might luck out. The SE swell is a perfect fit for this spot. This is the best session of the whole outlook—get in the water.
Thursday morning the 3rd of September keeps it clean with a 3ft swell from the ESE and a longer 11-second period, giving it extra punch. The combined energy is 278, still moderate. The wind is light and cross-off, so it’s another good window. But Thursday afternoon gets messy with a strong cross-shore wind.
From Friday the 4th through the 6th of September, it’s mostly a bust. Small swell, onshore winds, and choppy junk. The combined energy drops below 100 at times.
A week later on Monday the 7th of September, the morning shows a 7ft swell from the S with a 9-second period, and the energy is strong at 988. But it’s predicted to be too big for this break, so unless you’re an expert, stay away. The wind is cross-shore, so it’s not clean.
Tuesday the 8th of September morning has a 6ft swell from the SSE with an 11-second period, and the energy is very strong at 1091. The wind is light cross-shore, but the conditions are labeled marginal and questionable. It’s big, but not ideal.
The rest of the second week is mostly poor. There’s a brief window on Saturday the 12th of September morning with glassy conditions and a 4ft swell from the E, but it’s not a standout. After that, the wind and swell just don’t cooperate. The last few days from the 13th to the 15th are all onshore, small, and choppy.
So, bottom line: Wednesday morning the 2nd of September is your best call. Clean, solid waves, and the right swell direction. After that, Thursday morning the 3rd is worth a look, but the rest is a pass.
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.
