The Lowdown
Alright, let’s see what’s cooking for the next couple of weeks.
Right off the bat, Friday (21st) and Saturday (22nd) are a bit of a wash. The swell is tiny and weak, with poor conditions – not worth paddling out for. The water is a touch warmer than usual for this time of year at 68°.
Come Sunday morning (23rd), things start to look a little more promising. Estaleiro Reef is seeing a 2ft swell from the SE with a 12-second period, and the wind is glassy. That’s a rare treat – smooth, clean conditions. The combined energy is still low at 133, but for a quiet session, it’s surfable.
Monday (24th) sees a jump in energy with a 4ft SE swell carrying a 14-second period (585 combined energy), but the wind is cross-onshore, so it’s a bit messy. Still, the long period gives it some punch, and on a reef setup like this, those longer lulls between sets can make the paddle out a bit easier.
The standout for the first week is Tuesday morning (25th). Glassy conditions again, with a 3ft SE swell at 13 seconds (206 energy). The forecast says “expect good surf conditions” – and with clean glass, this is your best bet for a proper go. It’s small but clean.
Wednesday afternoon (26th) also looks tidy with a 3ft SE swell and glassy winds (460 energy). Another good window for a relaxed session.
Thursday morning (27th) stays clean with a 3ft SE swell, 13-second period, and light cross-offshore winds (382 energy). The reef will be working nicely.
Friday (28th) through Sunday (30th) mornings all have clean conditions with offshore or cross-offshore winds, and swell around 3–4ft from the E. The period drops to 8–9 seconds, so it’s more windswell, but with the right wind, Estaleiro Reef can still give you some fun little waves.
Monday (31st) morning is only “surfable but very ordinary,” but the afternoon brings a clean 4ft E swell, 8-second period (206 energy) with light cross-offshore winds – another good call.
Then we hit a rough patch. Tuesday (1st September) through Thursday (3rd) mornings are all poor with strong cross-onshore winds and choppy conditions. Not worth it.
The real highlight of the entire forecast shows up on Friday morning (4th September). That’s a 6ft ENE swell, but with a short 6-second period, and glassy winds. The combined energy is 547 – moderate, but the glassy conditions will make it feel clean. The afternoon also looks good: 5ft NE swell, 7-second period, with light cross-offshore winds (515 energy). This is the best on offer – a solid little pulse with perfect wind. It’s not huge, but for a reef, it’ll be peeling nicely.
Saturday (5th September) goes downhill fast with strong onshore winds and rain – a total washout.
So overall, the pick of the bunch is Friday the 4th of September. Glassy morning, clean afternoon, and a bit of size. Tuesday the 25th of August is your next best for a glassy, clean session. Keep an eye on the long-range stuff – it’s promising but not locked in yet.

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.
