The Lowdown
Alright, Rusty here. Let’s talk waves. The start of this 16-day stretch is a bit of a write-off – the first couple of days are blown out with crummy onshore winds. But it’s not all bad news, there’s some proper swell coming, you just gotta be patient.
First real chance is Wednesday the 11th. It’s not gonna be perfect, but there’s rideable surf on offer. The swell is short-period and a bit weak, but it’s a start.
The standout, the one you’ve been waiting for, is Saturday the 12th. We’re looking at 8 to 8ft of south swell with a 10-second interval, and the energy level is through the roof. The wind goes offshore, and it’s gonna be glassy and clean. This is the day to clear your schedule. The water’s a touch cooler than normal, about 64°, so grab the booties if you’re sensitive.
After that, it gets a bit bleak for a few days with onshores and rain making a mess of things. But then, Tuesday the 15th rolls around. The wind is offshore again, and there’s a solid 6ft of ENE swell with moderate energy. It won't be as big as Saturday, but the conditions will be just as clean. Another top-tier session.
The final week is all about picking your moments. There are a few mornings with clean conditions, but the swell is inconsistent and the winds are fickle. Nothing really holds together for a full day. There’s a few glimmers at the end of the week with offshore wind, but the swell is small. It's a waiting game.
So, to sum it up: your two best bets are Saturday the 12th and Tuesday the 15th. Both are clean, both have some push, and both are worth the effort. Make the most of them.
Rusty out.

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.
