The Lowdown
Alright, let’s talk about Estaleiro Reef. This is a reef break, intermediate level, and it’s inconsistent – it doesn’t just fire up out of nowhere. The first solid window is Sunday the 16th. The water’s reading about 66°, which is pretty much spot on for this time of year, so nothing weird going on there.
Sunday the 16th afternoon, we’ve got some clouds and a light cross breeze from the NE at 6 mph. The swell is 5 ft from the E with a short 8-second period. The combined energy is weak (276). It’s surfable, but it’s marginal. The best window starts to show on Monday morning the 17th. That morning is looking clean with a light cross-offshore breeze from the N at 6 mph. The swell holds at 5 ft from the ENE, period still short (8 seconds). The energy is still weak (279), but the clean conditions make it the pick of the early sessions. Tuesday the 18th and Wednesday the 19th are a write-off, honestly. The wind goes onshore, the swell drops, and it gets messy. By Thursday the 20th, the swell is dropping to 3 ft, energy is weak (89), and it’s just not worth a paddle.
Friday the 21st afternoon brings a nice change. A clean offshore breeze from the WNW at 6 mph hits the 3 ft E swell, period still short (8 sec). Energy is weak (176). It’s surfable, but nothing special. Then we hit a real flat spell. From Saturday the 22nd right through to the end of the month, the conditions are poor. The wind is mostly cross-onshore or onshore, and the swell gets confused. There’s a spike in energy on the 24th and 25th, with the swell hitting 5 ft and the combined energy climbing to 735 (moderate) and 796 (moderate), but the wind is onshore, and the period is short to mid-range. It’s going to be a choppy, blown-out mess, more suited to the kite crew than a surfer.
The real glimmer of hope comes right at the end. Monday the 31st morning is a beauty. The wind goes glassy, flat calm from the SE at 3 mph. The swell is 4 ft from the E, period 8 seconds. The energy is moderate (340). This is a clean, glassy morning, and for a reef break that’s inconsistent, that’s the standout. If you can get there, that Monday morning is the one to circle. The wind will be light and the waves will be clean. The rest of the second week is a bit of a gamble, with the light winds and moderate energy, but Monday the 31st is the clear winner.

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.
