The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cooking for the next couple of weeks.
There’s a bit of a slow start, but then things get real interesting. The first few days are a bit of a mixed bag, but the standout window is shaping up for Sunday the 26th, and there’s another promising pulse early in the following week.
Monday the 20th starts off with a glassy, clean 5 ft swell from the ENE at Praia do Porto (beach/jetty). The water is sitting at 63°, which is a bit colder than normal for this time of year. The combined energy is moderate (325), and with the wind being glassy, it’s worth a paddle. The afternoon stays glassy and clean at 5 ft.
Tuesday the 21st sees a bump in the swell energy. The morning is a bit messy with a cross-on wind, but the afternoon cleans up nicely with a cross-off breeze and a solid 6 ft from the NE, with strong combined energy (729). That’s a good session.
Wednesday the 22nd has a clean morning with offshore wind and 4 ft waves, but the afternoon goes to sh*t with a strong cross-on wind and choppy conditions. Skip it.
Thursday the 23rd is a solid day. Offshore wind in the morning with 4 ft from the SSW, and the combined energy is strong (506). The afternoon holds clean with a cross-off breeze and 5 ft from the S. Good surf.
Friday the 24th kicks off with a glassy morning, 5 ft from the SE and a longer period of 9 seconds, giving it decent shape. Combined energy is solid (644). The afternoon gets a bit iffy with onshore wind.
Saturday the 25th is a bit of a mixed bag. The morning is clean with a cross-off breeze and 4 ft waves. The afternoon brings a risk of thunderstorms but the wind goes offshore at 12 mph, with 5 ft from the ESE and strong energy (533). Worth a look if you don’t mind the lightning.
Now, here’s the big one. Sunday the 26th is the standout. The morning has a massive 10 ft swell from the SSE with a period of 10 seconds and an *insane* combined energy of 3689. That is a lot of power. The wind is offshore at 16 mph, so it should be clean. This is for experienced surfers only – way too big for beginners. The afternoon drops to 8 ft from the SE, still pumping with 1345 energy and excellent conditions for those who know what they’re doing. This is the session to aim for.
Monday the 27th is still solid, with a clean morning of 6 ft from the SE and offshore wind. The afternoon gets a bit onshore, so get out early.
Then things go quiet. From Tuesday the 28th through to Saturday the 1st of August, the surf is pretty poor. Mostly onshore winds, short period swells, and choppy conditions. There’s a big gap of poor surf for about 5 days.
But don’t give up. Monday the 3rd of August looks promising again. The morning is glassy, with a 6 ft swell from the NE and very strong combined energy (671). The afternoon holds clean with offshore wind. That’s another good one to mark on the calendar.
Tuesday the 4th of August starts glassy with 5 ft from the NE, but the afternoon goes onshore and messy.
So, overall: the cream of the crop is Sunday the 26th for the big, powerful, offshore swell, and Monday the 3rd of August for a clean, glassy session. Surf’s up.
Rusty.
