The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for Praia do Porto.
First thing you gotta know: the water is way colder than normal for this time of year. We’re talking a serious anomaly of -3°, so a wetsuit is non-negotiable. It’s gonna feel like a different season out there.
The start of this forecast is a write-off. The first few days are a mess of onshore and cross-onshore winds, with poor, choppy conditions. The swell is there, but it’s messy. From Thursday the 16th right through to Sunday the 19th, it’s all pretty average. Combine that with wind speeds up to 15 mph and it’s a pass for me.
It’s not until Monday the 20th that we get a glimmer of hope. That morning, the wind goes completely glassy – 0 mph – and we’ve got a 5ft swell from the ESE at 8 seconds. The energy is moderate (357). The conditions are clean, and it’s the first real sign of life. You’ll want to be on it early, because the afternoon turns onshore again.
Tuesday the 21st is a solid day. The morning starts with a light offshore breeze from the SW at 3 mph, with a 5ft NE swell. The combined energy is moderate (363) and the waves will be clean. The afternoon stays clean with a cross-offshore wind. That’s a good one.
Wednesday the 22nd is a sleeper. Moderate rain, but the wind is light and cross-offshore. The swell drops to 4ft from the S, but it’s clean all day. For a small-wave board, it’ll be fun.
The real standout, the one you circle on the calendar, is Thursday the 23rd. That morning is glassy – 0 mph wind – with a 5ft swell from the SSE, and a period of 10 seconds. The energy is moderate to strong (551). It’s clean, it’s got some push, and it’s the best conditions we see all week. Don’t sleep on it.
Things get a bit wild again after that. Friday the 24th has a 6ft S swell but short period. The morning is cross-shore and messy, but the afternoon cleans up with a cross-offshore breeze. Saturday the 25th has a strong offshore wind – 22 mph from the SW – and a 5ft SE swell. That’s a lot of wind, but it’s offshore, so expect clean, bumpy faces. More of a challenge.
Then we hit another quiet patch. Sunday the 26th and Monday the 27th have some good, clean conditions with light winds, but the swell is inconsistent. Monday the 27th morning is a gem: glassy, and a 6ft ENE swell with 7-second period. Combined energy is strong (707), and it’s rated as very good. That’s a solid morning session. The afternoon, however, is ruined by an onshore breeze.
The rest of the run into the end of the month and into the first days of August is a real mixed bag. There’s a moment on Thursday the 30th with a glassy morning and a 4ft E swell at 10 seconds (506 energy), but otherwise, it’s mostly onshore wind and chop. The good windows are short and sharp.
Overall, the best of the best is Thursday the 23rd for the glassy, clean conditions and decent swell. Monday the 27th morning is a very close second. The rest of the time, you’ll be picking your windows carefully.
Rusty.

Information about the Praia do Porto Surf forecast
The above surf forecast table for Praia do Porto provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia do Porto can be found by selecting the local surf guide option on the grey menu. Our Praia do Porto 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 (Praia do Porto) 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 Praia do Porto 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.
