The Lowdown
Alright, Rusty here, breaking down the goods for Estaleiro Reef.
This reef breaks inconsistent, but when it lines up with an ESE swell, it can be a gem. The start of the period is pretty slow, so don’t rush.
We kick off Wednesday the 12th of August with a small 3ft swell out of the SE. The wind is light offshore, so it’s clean, but the wave energy is weak (220). Just a small, tidy wave to get wet.
Thursday the 13th is a total loss with onshore wind. Friday the 14th morning is flat, but Friday afternoon saves the day. The swell is still small at 3ft from the SE, but the period jumps to 14 seconds, giving it some real push. The water temp is 66°F, which is average for the season. The combined energy is 312 (moderate). With glassy conditions, that afternoon session is a real treat.
The weekend picks up. Saturday the 15th has proper size at 5ft from the ESE, with a light cross-offshore breeze. The period is short at 8 seconds, so it’s a bit windswell-ish, but it’s clean. Energy is moderate to strong (316-483). Fun, but not the peak.
Sunday the 16th has similar size but cross-shore wind kills the quality.
The first real standout is Monday the 17th of August. The morning delivers 5ft from the E with a cross-offshore wind and clean conditions. The period is 9 seconds, and the combined energy is 343 (moderate). This is the pick of the first week – good size, clean, and the break should handle it. This is intermediate territory, so keep the beginners out.
Monday afternoon bumps to 5ft, but the wind goes cross-shore and adds chop. Tuesday the 18th is a complete mess with strong onshore winds and poor surf.
After a quiet stretch, Wednesday the 19th of August offers a glassy morning with a 4ft swell from the ENE. The energy is moderate (202), and it’s clean. A nice little window.
Then we hit a huge spike.
The biggest event is Sunday the 23rd of August. The forecast shows a massive 8ft swell from the SSE, with an 11-second period. The combined energy is an enormous 1904 (very strong). But this is too big for Estaleiro Reef. The report says it’s too big for this break. This is expert-only territory, and even then, it’s going to be a beast. The wind is light and cross-offshore in the morning, so it will be clean, but the size is the story.
Monday the 24th of August then drops to a much more manageable 4ft from the SE. The wind is cross-offshore, the period is a solid 14 seconds, and the energy is strong (525). This is another excellent window – clean, proper groundswell, and the right size for the intermediate crowd. This is your second best window.
After that, the wind turns onshore and the quality drops off a cliff through the rest of the forecast.
So, to wrap it up: the first week is small and clean, with Friday afternoon the 14th and Monday morning the 17th as the picks. The second week features a huge, expert-only day on the 23rd, followed by a much cleaner, more manageable day on the 24th.
Pick your moments and stay sharp.
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.
