The Lowdown
Alright, let's break down what’s on tap for Estaleiro Reef over the next couple weeks.
It’s a slow start, no doubt. The first few days are a bust – small, choppy, cross-onshore winds making a mess of things. Nothing to bother with on Monday or Tuesday.
The first real chance comes on Wednesday the 12th. The morning is glassy with a 3ft southeast swell, period around 12 seconds. That’s a clean window. The afternoon gets even better with a light offshore from the west, clean surf, same 3ft swell. That’s the first real session.
Thursday the 13th morning is a beauty: clear, light offshore from the west, a 3ft southeast swell with a 15-second period. That’s long-period groundswell, perfect for this reef – it’ll wrap in nicely with some punch, and the long sets make paddling easier. The water temp is about 67°, which is standard for this time of year. The afternoon gets blown out by a strong cross-onshore, so make it an early one.
Friday the 14th morning is another gem. Glassy conditions, 2ft SE swell, clean lines. The afternoon gets a little crossed up, though.
The weekend is a bit of a mess. Nothing solid.
The next real standout is Tuesday the 18th morning. A clean 4ft swell from the SSE with a light cross-offshore from the NW. Swell energy is moderate. The period is short at 8 seconds, so it’ll be a bit more stacked-up, but the wind is right and the size is there.
Another nice window comes on Thursday the 20th afternoon – glassy, 2ft SE swell with a 13-second period. Small but clean.
Friday the 21st morning is a good one: 4ft from the ENE, 8-second period, and glassy conditions. Worth getting up for.
Looking way ahead, Tuesday the 25th shows a massive jump in swell energy – 6ft from the east, but with a cross-onshore wind from the SSE. The energy reading is 777, which is strong, but the quality will be lumpy. Probably better for a kite than a surfboard that day.
The pick of the whole run? Thursday the 13th morning or Friday the 14th morning. That combo of light offshore, glassy water, and that 13 to 15-second groundswell is what Estaleiro Reef was made for. Crowds can pop up sometimes, so get there early. The long-range stuff past the 21st is promising but still a bit of a gamble.

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.
