The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s heading our way for Praia do Porto. Gonna be a bit of a slow start, but there’s some real quality sneaking in if you’re patient.
The water is sitting at 61°, which is much colder than normal for this time of year – a solid 5° below average. You’ll be wanting a decent steamer for sure.
The opening weekend is a write-off. Saturday the 18th and Sunday the 19th are nothing but messy, cross-onshore winds and poor surf. The energy is moderate to strong (1178 and 908), but it’s all choppy and ugly. Don’t bother.
The first real chance comes on Monday the 20th. The morning is the standout. We’ve got a clean 7ft NE swell with glassy conditions – the wind is dead calm. The energy is strong (1048). It’s a beach/jetty setup, so that long period isn’t an issue, and the offshore wind direction is SW which is a bonus. It’s a bit of a standout for the week, but the afternoon turns onshore and messy.
Tuesday the 21st is also a good call. The morning has a clean 5ft ENE swell with a light offshore wind from the SW. The afternoon turns glassy. Nice, clean conditions all day. The energy is moderate (322-327).
There’s a bit of a lull mid-week with some rain and smaller swell, but conditions stay clean.
Looking further out, Saturday the 25th afternoon is a great shout. The swell bumps up to 6ft from the ENE, the wind goes glassy, and the energy is strong (730). It’s a real surprise in the middle of a lean patch.
Then, the big one. Saturday the 1st of August morning. This is the pick of the whole forecast. We’ve got a 8ft E swell, glassy conditions, and massive energy (1697). This is excellent surf for experienced surfers. The wind is calm, the waves are pumping. The afternoon turns onshore, so get on it early. It’s a bit of a wait, but it looks like it could be worth it.
So, for the best on offer: Monday 20th morning for the glassy 7ft NE swell, and Saturday 1st August morning for the big, clean 8ft E swell. The rest is a mix of average conditions and onshore slop. Keep your eyes on the sky for that first Saturday in August.
Rusty.
