The Lowdown
Alright, let’s get into it. This is Rusty, bringing you the straight-up word on the surf for Praia do Porto.
Right now, it’s quiet. There’s not much happening as we kick off Wednesday the 22nd of July. The morning is a write-off—choppy, cross-on wind, and poor conditions. But hang in there, because the afternoon shapes up nicely. By then, the wind swings offshore-light and we’re looking at clean 5ft waves from the NE. It’s small, but it’s a start.
The best window in the early part of the forecast hits on Thursday the 23rd afternoon—solid, powerful, and for experienced surfers only. We’ve got a 7ft SSW swell with a 9-second period and offshore wind. The combined swell energy is very strong (1384), making for punchy, well-shaped waves. This is the standout call for the first week. Beginners, sit this one out.
Friday the 24th and Saturday the 25th serve up cleaner, more manageable surf. Friday starts with 6ft from the SE and light offshore wind, while Saturday morning is absolutely magic—glassy conditions, 5ft SE swell, and calm winds. That’s a beautiful, user-friendly session for intermediate surfers. But as we move into Sunday the 26th, it drops right off. Onshore wind, small swell, and we’re into a flat spell that stretches for several days.
From Sunday the 26th all the way through to the end of July, it’s pretty grim. The 27th through the 31st are mostly onshore, tiny, and not worth paddling out. A little bump appears on the 29th and 30th with small, clean waves, but nothing you’d set your alarm for.
Now, for the next week—and this is the one to circle on your calendar—the surf fires back up on Sunday the 2nd of August. We’ve got clean, glassy 4ft waves from the S with a long 12-second period. The real gem, though, is the 5th of August, Wednesday morning. That’s an expert-only session: a solid 8ft SSE groundswell, 11-second period, glassy conditions, and combined energy through the roof (1671). This is the standout of the whole 16-day window. It’s a full week out, so keep an eye on it, but the potential is huge.
Water temp is around 66°F, which is pretty normal for this time of year.
Alright, that’s the full picture. Praia do Porto’s got two real highlights: Thursday the 23rd afternoon for experienced surfers, and that glassy Wednesday morning on August 5th for the big-wave crew. The flat spells in between are dry, but the quality when it comes is worth the wait.
Rusty.
