The Lowdown
G’day, Rusty here, lookin’ at what’s on offer for Praia do Porto. There’s a bit of a wait for the good stuff, with a few days of ordinary conditions before we get a proper window. The water’s sittin’ around 66°, which is pretty much spot on for this time of year, so nothing unusual there.
Alright, let’s get into it. Thursday the 23rd of July kicks things off with a solid 6ft south swell, coming in at 8 seconds. It’s got a moderate energy level (576) and a clean offshore breeze from the SSW. This is a good start, expect clean surf. The real standout, though, is Friday morning the 24th of July. The swell drops to 6ft but shifts to the southeast with a longer 9-second period, and the wind goes glassy – dead calm. The energy’s bumped up a bit (670), and the conditions are set to be very good. This is the pick of the first week, no doubt.
Saturday the 25th of July sees the swell drop to 5ft from the southeast, but the wind swings cross-onshore, messing up the surface. Conditions are marginal. By Sunday the 26th, the swell fades to 3ft, and with a longer 12-second period but cross-onshore winds, it’s poor. The wave energy is weak (367). Monday and Tuesday are small and weak, with a few glassy moments but nothing to get excited about. Wednesday the 29th has a brief glassy window in the afternoon on a 2ft, 10-second south swell, but it’s ordinary.
Thursday the 30th of July is a bit interesting – a small 3ft easterly swell with an 8-second period, and a clean offshore wind in the morning. Energy is low (177), but it’s clean. Still, not a standout.
We hit a dry spell from Friday the 31st of July through to Saturday the 1st of August, with poor conditions and messy wind. Then on Sunday the 2nd of August, the morning glass-off returns with a 3ft south swell and a long 11-second period. Energy is moderate (324) and the waves look clean – a solid, if small, option.
Now, into the second week, things get more promising but less certain. Monday the 3rd of August brings a 5ft SSE swell with a 10-second period, but the wind is onshore and messy. The energy’s getting stronger (613), but the wind is a problem. Tuesday the 4th is similar. The real standout of the whole outlook is shaping up for Wednesday the 5th of August and Thursday the 6th. On Wednesday morning, we’ve got a 8ft east swell with a 9-second period, and the energy is very strong (1394). This is a big, powerful swell, but the wind is onshore, so it’s marginal. Thursday morning sees the swell hit 8ft from the east-northeast, with an even stronger energy reading (1544). This is pushing into expert-only territory, and with the wind still onshore, it’s not clean. The long-range call is promising for size, but the wind needs to cooperate.
Friday the 7th of August has a 7ft ENE swell with a cross-offshore breeze, which cleans it up a bit, but the energy is still moderate (497). Not a standout, but a decent end to the period.
Overall, the best bet is Friday morning the 24th of July – glassy, clean, and a solid 6ft SE swell. The second week’s big swell on the 5th and 6th is a raw power event, but only for the experienced crew, and the wind is a gamble.
Rusty.

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.
