The Lowdown
G’day, Rusty here. Let’s unpack what’s coming for Estaleiro Reef. This is a spot that needs a bit of patience, but there are a few solid sessions on the horizon. The water’s sitting around 68°, which is pretty normal for this time of year.
The first real chance to get wet comes Thursday morning, September 3. We’ve got a clean 3ft swell from the ESE, period around 11 seconds, and light offshore winds from the NW. The combined energy is moderate (280), and it’s glassy. That’s a nice little session for intermediates. The afternoon gets ruined by a cross-shore breeze, so hit it early.
The standout for the first week is Wednesday, September 9. The morning shows a 4ft ENE swell with a short 7-second period, but offshore W wind keeps it clean. The afternoon is the real star: zero wind, glassy conditions, and a 5ft NE swell with a 7-second period. The combined energy jumps to 442 (moderate), and the wave quality is good. This is the pick of the bunch – glassy, clean, and fun.
Thursday, September 10, brings more size. Morning has 6ft ENE with glassy conditions and combined energy at 695 (strong). That’s for experienced surfers. The afternoon gets 8ft ENE with 8-second period and combined energy of 1319 (very strong). That’s too big for this reef – experts only, and even then, it’s a handful. The wind is offshore and glassy, but the size is the issue.
Friday, September 11, morning offers a cleaner 5ft ENE swell, offshore wind, and combined energy of 305 (moderate). Good for intermediates. The afternoon turns to junk with cross-onshore winds.
The second week has some clean windows. Sunday, September 13, morning: 4ft E swell, 9-second period, offshore NW wind, combined energy 331 (moderate). Clean. Monday, September 14, morning: 4ft SE swell, 10-second period, cross-offshore wind, combined energy 371 (moderate). Clean and surfable. Tuesday, September 15, both morning and afternoon are clean with offshore winds, 4ft and 4ft SE swells, periods of 12 and 11 seconds, and combined energy around 420 (moderate). That’s a nice long-period groundswell that will work well on the reef.
The best on offer is Wednesday, September 9 afternoon – glassy, clean, and fun. For a bigger wave, Thursday, September 10 morning is a strong option for experienced surfers. The second week’s best is Tuesday, September 15, with clean conditions and a solid groundswell.
Crowds at Estaleiro Reef are sometimes around, so you might have company. The spot is inconsistent, so when it’s firing, it’s worth the wait.

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.
