The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s lined up.
We’re starting with a bit of a flat, lifeless stretch. Nothing worth paddling out for at first. The first real window of opportunity here at Estaleiro Reef doesn’t open up until the morning of Saturday the 22nd of August, and even that one’s a bit of a gamble. You get a punchy 6ft swell coming from the SSE, but it’s got a cross-onshore breeze messing with it and the combined energy is a moderate 848. Clean lines will be tough to find. Still, it’s the first swell of note after a quiet gap.
The real standout, the one you want to make a plan for, is Tuesday the 25th of August. Morning session is the pick. We’re looking at 3ft of groundswell from the SE with a 13-second period, pushing a combined energy of 301. The wind goes glassy – dead calm from the west – so the surface will be like a mirror. The water here is sitting at a toasty 68°, which is a touch warmer than usual for this time of year. This is the session for smooth, lined-up reef waves.
Keep an eye on Wednesday the 26th of August afternoon as well. The swell drops a little to 3ft, but the period stretches out to 16 seconds, giving it some serious push and a combined energy of 501. Light offshore winds from the SW will keep the faces clean. This is one of those moments where the reef really starts to groom the swell into proper shape.
Into the following week, Friday the 28th of August morning has a clean 5ft pulse from the ENE with a light cross-offshore breeze. It’s not the same quality as the mid-week window, but it’s a solid runner if you’ve got a free morning.
After that, the forecast gets a bit messy again with onshore winds and choppy conditions. There’s a late push on Sunday the 30th of August afternoon with a 5ft NE swell and a 9-second period, but the cross-shore breeze spoils the party.
From the 31st of August right through to the end of the run, it’s all cross-onshore slop. The wind swings southerly and stays there, with moderate to fresh breezes. The swell sticks around but the quality drops hard. If you’re itching for a session, the 25th and 26th of August are your gold.
Stay frothy.

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.
