The Lowdown
Alright, ol’ mate Rusty here. Let’s have a look at what’s on offer. The good news is we’ve got some stuff to work with, but it’s a bit of a mixed bag to start. We’ll be surfing at Praia do Porto, a beach/jetty setup that’s fairly exposed and prefers swell from the SE. The water is sitting at 62°, which is a bit colder than normal for this time of year – that’s about 3° cooler than usual, so you’ll be reaching for the extra rubber.
So, the first proper window where it all comes together is Monday, July 20th. The morning is looking prime – we’ve got a clean 7ft swell from the NE, period of 8 seconds, and the wind is glassy. Absolutely no chop, which is a major positive. The combined swell energy is moderate at 881, so there’s some push there. The afternoon fades a bit with a cross-on breeze, but the morning is the pick. Tuesday, July 21st, is also a beauty. Glassy conditions again in the morning with 5ft from the ENE, and then the afternoon turns glassy with 6ft from the NE. The energy is up to 733 in the afternoon, so expect some fun, clean lines.
Wednesday, July 22nd, still has a glassy morning with 4ft, but the wind swings onshore in the arvo and it gets messy. Then we get a nice shift. Thursday, July 23rd, brings a clean offshore wind from the SW, with a 6ft to 7ft swell from the S and SSE, period 9 seconds. This is a proper setup with moderate energy (639-704). The wind is offshore and clean, so the waves will be holding up nicely. Friday, July 24th, keeps the good vibes with light offshore winds and 6ft to 6ft from the SE, glassy conditions in the afternoon.
The standout in the whole run, though, is Thursday, July 30th. We’ve got a solid 8ft swell from the S, with a 10-second period, and the combined energy is a massive 2308 – that’s strong wave energy. The wind is light and cross-off, so the surf will be clean and powerful. That’s a big day for experienced surfers only. The afternoon then drops to 7ft and 811 energy, still very good.
For the first week, the best call is Tuesday July 21st afternoon for the glassy conditions and solid 6ft, or Thursday July 23rd for the offshore winds. The real standout is Thursday July 30th for the big, clean groundswell.
There is a bit of a flat patch from around July 25th to July 29th where the surf is small or messy, so don’t bother paddling out then. After that, the last day of the run, August 1st, has a glassy morning with 5ft from the NE, and then a clean offshore wind in the afternoon with 5ft, so that’s a decent end to the outlook.
Right, that’s the story. Get out there and get wet.
