The Lowdown
Alright, let's get this straight. This is a 16-day outlook for just one spot, so it's a deep dive on what's coming for Estaleiro Reef.
Right off the bat, we've got a bit of a wait. The first few days are a tease. You've got some small, workable waves but nothing that's really going to get the blood pumping. The swell is pretty weak, with a combined energy reading of just 236, and it's a short-period 8-second windswell from the ENE. On Friday morning, the 17th, it's clean with a light offshore, but it's just 4ft. It's surfable, but you’ll be scratching for the good ones. The afternoon gets cross-shore and a bit bumpy. Saturday and Sunday are more of the same – small, clean in the mornings but turning messy as the day goes on. It's a pretty flat start to the window.
Now, we do see a bit of a pulse coming through on Wednesday the 22nd and Thursday the 23rd, but the swell drops right down to 3ft and 3ft. It gets glassy on Wednesday morning, which is nice, but you're surfing on tiny waves. It's a quiet period.
Then we hit a bit of a rough patch. The 24th and 25th see the wind turning onshore, making things choppy and ugly. Not worth getting wet for, honestly.
But then, hold on to your board. The real action starts to build towards the end of the month. Things start to get interesting on the 29th of July. The swell picks up and the period extends. By Thursday the 30th, we’re looking at a monster pulse. The combined energy jumps to a massive 1650, and the swell is 7ft from the SSE with a 12-second period. That's a lot of power. However, the forecast says it's too big for this break. This is a reef, and that much water moving around could get dangerous. The wind is light cross-onshore, so it might be a bit of a washing machine. This is strictly for the brave and experienced.
Now, for the standout. The best chance for a proper session looks like Friday the 31st of July, and into Saturday the 1st of August. On Friday morning, the swell drops to a more manageable 5ft, but it's got a solid 14-second period from the SE. The wind is light offshore. The energy is still high, sitting at 976. The report says "very good surf conditions," and I can see why. That's a proper groundswell with clean, offshore winds. The afternoon gets even better for the experienced crew, with 6ft from the ESE at 13 seconds and an energy reading of 1239. The wind is light cross-offshore, keeping it clean. This is the one to circle on the calendar. It’s a long-range call, so keep an eye on it, but it’s promising.
Saturday morning looks like a solid backup, with 5ft of clean swell and a light offshore breeze. The energy is still healthy at 872.
So, the long and short of it: The first week and a half is a slow grind with small, average waves. The second week builds into a powerful swell that might be too much for the reef on the 30th, but then cleans up into a really good window on the 31st and 1st. That's your best bet.

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.
