The Lowdown
Alright, Rusty here. Let’s break it down.
Same story – Estaleiro Reef is the only game in town, and it’s an inconsistent reef break. The next 16 days look slim overall, with a couple of small windows that could work if you’re on it.
We kick off on Tuesday, 18 August. Morning swell is about 4ft from the ENE with a short 8-second period, but the wind is a light cross-off from the NW – clean enough to surf. The combined energy is moderate at 208. Afternoon bumps up to 4ft, still clean.
Wednesday morning, 19 August, drops to 3ft but goes glassy with a light SSW breeze. That’s a beautiful combo for a small wave – clean and smooth. Energy is weak at 118. Afternoon gets messy.
From Thursday, 20 August, through Sunday, 23 August, it’s mostly small and weak, with a moment on Friday morning, 21 August – 2ft and offshore wind, but the energy is only 51 (very weak). Not worth suiting up for unless you’re desperate.
Monday, 24 August, is a notable ramp-up. Swell hits 4ft from the SE with a 14-second period – proper groundswell. The energy jumps to 433 in the morning and 504 in the afternoon (strong). The wind is cross-on, which keeps it from being perfect, but there’s enough juice for a reef break.
Tuesday, 25 August, is the standout. Only 3ft from the SE at 13 seconds, but the wind is light cross-off from the NW, so it’s clean. Energy is 253 (moderate). Water temp is about average for the time of year. Crowds are possible here. For an inconsistent spot, this is your best window.
From Wednesday, 26 August, onward it’s mostly poor – onshore winds, rain, and choppy conditions. There’s a small chance on Friday, 28 August – 2ft with offshore NW wind – but it’s barely ridable.
The final week from 29 August to 2 September is a bust: constant cross-on winds, rain, and rough conditions. By 2 September, heavy rain, 2ft from the SE at 13 seconds, but it’s all cross-on and ugly.
Bottom line: Aim for Tuesday, 18 August, for the cleanest head-high waves, or Tuesday, 25 August, for better quality in smaller surf. The rest is a washout.
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.
