The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Praia do Porto over the next couple of weeks.
It's a bit of a mixed bag to start with, but there's some real promise if you're patient. The water temp is sitting at about 66°, which is bang on normal for this time of year, so no surprises there.
The first real standout is Wednesday morning, the 2nd of September. We've got a 7ft SE swell rolling in with a 10-second period. The combined energy is solid at 935 (moderate wave energy), and we've got a clean 15 km/h offshore wind from the SW. That's going to put some real shape on the waves at Praia do Porto. This is a beach/jetty setup, so those long-period swells can sometimes break a bit straight, but with that offshore wind tidying it all up, it should be a fun morning for the more experienced crew. It's a bit much for the beginners though at over 5ft. Crowds are possible here, so get out early.
After that, Thursday the 3rd looks pretty average as a stiff onshore wind chops things up, and Friday the 4th is only small. We get a little pulse back on Saturday the 5th with a 3ft S swell, and light offshore winds again, making it clean and much more manageable for the beginner plus crew. That's a nice little session.
We go through a bit of a quiet patch early in the second week – Sunday and Monday are okay but nothing to write home about. Then, things get interesting again. The real standout for the entire period is Monday the 14th of September. We're looking at a 7ft ENE swell with a short 8-second period, but the combined energy is a massive 1405 (strong wave energy). What makes this a cracker is the 15 km/h offshore wind from the SW, keeping it clean. This is described as excellent for experienced surfers, and at over 7ft, it's definitely not for the faint-hearted. The wind will be holding it up nicely, so expect some power.
The following day, Tuesday the 15th, is a bit of a letdown with onshore winds, but then we get a glassy, calm morning on Thursday the 17th of September. A 5ft ESE swell, glassy conditions, and a score that suggests very good surf. It's a smaller, cleaner option for the end of the run.
So, to sum it up: the best bet is Wednesday morning the 2nd for a solid, clean swell, or if you're after a bigger, more powerful session, mark Monday the 14th in your calendar. The glassy day on the 17th is a great, less-crowded backup.
Rusty.
