The Lowdown
Alright folks, Rusty here.
We’ve got a slow start for this region, but there’s a nice little window of clean surf to look forward to. The first real chance comes on Saturday morning, August 15th. The water temp is sitting at 66°, which is just about average for this time of year, so no need to worry about a cold shock.
Let’s talk about the standout. Saturday morning, August 15th at Estaleiro Reef is your best bet early on. We’re looking at a 5ft swell from the East with a short period of 8 seconds (moderate wave energy of 374). The real magic here is the wind – it’s dead glassy from the North. That means the surface will be like a mirror, which is a massive plus for a reef break. The waves will be clean and fun, even if the swell isn't huge. Keep in mind this spot is a reef, so it can be inconsistent, but when it’s glassy like this, it’s worth the wait.
The surf dips a bit after that, but we get another solid run from Monday morning, August 17th through Tuesday afternoon, August 18th. The swell shifts to a slightly better direction (ENE) and picks up a bit more energy (420 to 565). The wind stays light and cross-offshore, keeping things clean. Expect waves around 4ft to 5ft with a period of 9 seconds. It’s not huge, but it’s clean and rideable.
Looking further out, the end of the month is promising but a bit more uncertain. Thursday afternoon, August 27th brings a glassy and clean 5ft swell from the East, and the following morning, Friday, August 28th, has a proper offshore wind from the West, making for a really clean 4ft wave. The very last day, Saturday, August 29th, has glassy conditions again with a 3ft ENE swell – a nice way to finish the forecast.
The middle of the week around August 23rd and 24th sees a pulse of much bigger swell (up to 7ft from the SSE), but the wind is all wrong – cross-onshore and choppy. That one’s a pass for surf, but it might be worth a look for kite surfers if that’s your thing.
Overall, stick to the mornings with glassy or light offshore winds for the best chances. The reef is sensitive to wind, so those clean windows are golden.
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.
