The Lowdown
Alright, let’s get into it.
The next couple of days are a write-off, plain and simple. We’ve got some messy, short-period swell and onshore junk making a mess of things. Don’t even bother looking at the water until we get past this initial rough patch. We’re looking at a couple of days of nothing before things start to clean up.
Sunday, August 9th is where it starts to get interesting. The wind swings offshore for the morning, and while the swell is a bit average at 4ft from the SSE, there’s decent energy behind it. This will be your first real chance to get wet, but it’s not the standout.
The real winner here is Monday, August 10th. We’ve got a proper groundswell from the south, pushing 7ft in the morning, with that clean offshore flow holding all day. The period is a nice, well-set 13 seconds. This is the pick of the first week. Praia do Porto will be handling this well, with those long-period lines wrapping in nicely. It’s got a good shape to it, not too crazy, but enough push to get you moving.
Tuesday the 11th is also very good, with a drop in size to around 6ft but with the wind going glassy in the afternoon. That’s a beautiful thing to see. The swell is still from the south with a 12-second period. This is a super fun day, especially for a longer board.
There’s a bit of a lull and some cross-onshore junk on Wednesday and Thursday, but nothing terrible. We get a bit of a reset on Thursday the 13th with a glassy morning and a 5ft, 12-second SSE swell. It’s worth a paddle if you’re keen.
Friday, August 14th has some size again, 7ft in the morning, but the wind starts to get messy, turning cross-shore and then cross-onshore in the afternoon, so it won’t be as clean.
The following weekend and into the new week, from the 15th to the 19th, things go a bit flat and junky. The swell drops, but more importantly, the wind is onshore and the period drops right out to 7-8 seconds. That’s just windswell mush. This is a proper blank run of about 5-6 days where you’re better off doing something else. The water temp is sitting pretty average for this time of year, so no surprises there.
Looking further out, there’s a glimmer of hope for Thursday, August 20th. The morning is dead glassy, with a small 4ft SE swell at 12 seconds. It’s small, but it’ll be clean. Then, the real long-range promise is Friday, August 21st. We’ve got a S swell at 5ft, 10-second period, with offshore WSW winds in the morning. It’s not huge, but it could be a fun, clean end to the run. It’s a way off, so treat it as promising rather than a sure thing.
Overall, Monday the 10th looks like the standout for quality and size. Tuesday the 11th is a close second for the clean conditions. Don't sleep on that Thursday the 20th glass either. For a beginner, keep in mind that anything over 5ft is getting into more challenging territory, and when it’s over 8ft, it’s expert only. This run doesn’t get that big, but Monday’s 7ft will still be a handful for some.
Rusty out.

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.

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.
