The Lowdown
Alright folks, Rusty here. Let's get into it for the next couple of weeks at Praia do Porto. We've got a promising start before the wind turns on us, and then a solid run of clean conditions to close out the period.
The opening window is looking good. Tuesday the 11th kicks things off with a solid 7ft southerly swell, a 12-second period, and a clean, offshore breeze. The water is sitting at 67°F, which is pretty much normal for this time of year, so you can leave the thick rubber at home. The combined energy is pumping hard at a strong 1294, so there's plenty of power in the water. That morning session is the standout for the first few days – clean, punchy lines that will be a lot of fun.
We get a brief window again on Thursday morning the 13th. The swell is still a solid 7ft from the south, but the period jumps to a very long 14 seconds. This is a proper groundswell, and with a light offshore wind, it's going to be an excellent day for experienced surfers. The energy is very strong at 1559. This is a top pick.
Friday the 14th is a bit of a mixed bag. The morning is glassy, with a 5ft south swell and a 13-second period. The energy is still moderate at 1031, and it will be clean. The afternoon, however, gets a cross-onshore wind and the swell jumps to 7ft, which makes it a bit messy.
From Saturday the 15th right through to Tuesday the 18th, it's a bit of a write-off. The wind goes onshore or cross-onshore, blowing out what swell there is. The period drops to short 8 seconds, and the energy values fall away. There's a brief respite on Tuesday the 18th morning with a moderate offshore wind and a 5ft swell, but the energy is only a weak 394, so it's not going to be anything special.
Wednesday the 19th and Thursday the 20th are a bit cleaner with offshore winds, but the swell is small, dropping to 5ft and then 4ft, and the energy is weak. The period is short, so it's mostly for the longboard or a bigger craft.
The real magic, and the absolute standout of the entire forecast, is waiting for you on Monday the 24th. The afternoon session is going to be pristine. The swell is 7ft from the south, a very long 14-second period, and the wind goes glassy. The combined energy is a massive 1484. This is a heavy, powerful, clean swell. It's a call for the experienced crew, but it will be worth the wait.
The very end of the period, on the 25th and 26th, sees a big jump in size with a 10ft swell from the SSE and a very long 16-second period, but the wind is turning cross-onshore, making it a messy proposition. The energy is extremely strong (3873), but the conditions won't be doing it justice.
Overall, the best bets are the Tuesday morning 11th, the Thursday morning 13th, and the glassy Monday afternoon 24th. The rest of the run is a mix of wind issues and small waves.
Rusty.
