The Lowdown
Alright, mates, Rusty here. Let's size up the surf ahead for our stretch of coast, focusing on Estaleiro Reef. It’s been a bit of a mixed bag lately, and the next couple of weeks are going to test our patience more than our paddle stamina.
Right off the bat, the start of this period is a write-off. Monday the 10th and Tuesday the 11th are looking poor, with onshore breezes making a mess of things. We're talking small, weak, and choppy. Not worth suiting up for. It’s going to be a slow grind to get things cleaning up.
Things start to turn around on Wednesday the 12th. The wind swings offshore and the surf cleans right up. We're still looking at pretty modest 3ft waves, with a moderate energy reading of 215. It's not big, but it's clean and that's a start. The water temp is sitting at 67°F, which is about average for this time of year, so not a shock to the system. Thursday the 13th morning is the real standout early on; that’s when we get that lovely glassy 3ft swell, with a long-period of 15 seconds and energy up to 335. It’s a reef break, so that long period will help it shape up nicely, offering some proper lines even at that size. This is the best option we've got until the following week. Though the afternoon does get chopped out, the morning looks prime.
After a few more average days, the next real highlight is on Friday the 21st of August. The morning shows a big jump in energy, up to 657, with a solid 3ft of ESE swell and a good 14-second period. With light offshore winds, this is shaping up to be the best surf of the whole forecast. It's a bit of a wait, but this one has the look of something special. Just keep in mind the afternoon wind swings onshore and kills it.
Beyond that, there’s another possible window around Tuesday the 25th with a clean 4ft of ENE swell in the morning, but the wind is forecast to get hairy by the afternoon.
So, if you're keen, the morning of Thursday the 13th is your early call, but the standout is undoubtedly the morning of Friday the 21st. And remember, Estaleiro can be inconsistent, so pick your moments when it's clean. Until next time, this is Rusty, 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.
