The Lowdown
Alright, I’m Rusty, and I’m looking at what’s goin’ on for our stretch of coast. The forecast window is a full 16 days, but I gotta be straight with you—it’s a slow start. There’s a real long gap here with nothing worth paddling for. The first couple of weeks are a grind, but there’s a light at the end of the tunnel.
The first real chance to wet your line comes on Friday the 23rd of July. Before that, from the 17th through the 22nd, it’s a write-off—poor conditions, small weak swell, and messy wind. That’s a solid six days of no-go. Save your wax.
On Friday the 23rd, the morning session at Praia do Aventureiro shows a little pulse. The swell is 3 ft out of the SSW, with a period of 10 seconds, and the wind drops to glassy. The combined energy is moderate (196). It’s not big, but it’s clean. That’s a surfable window if you’re keen for a longboard or a foamie. The water temp is a mild 71°, and that’s basically normal for this time of year—nothing weird about it.
Saturday the 24th and Sunday the 25th stay small but rideable. The swell holds around 3 ft to 3 ft from the south, with clean conditions in the mornings thanks to light cross-offshore breezes. A few tiny rollers, nothing to get excited about.
Now, if you’ve got patience, the real standout is sliding into view on the morning of Tuesday the 28th of July. That’s the pick of the whole run. The swell is 4 ft from the S, period 13 seconds—that’s a proper groundswell. The wind goes glassy. The combined energy is strong (614). The break is a point, so that long-period energy will wrap in nicely. Conditions are set to be clean and good. This is the one you circle on the calendar. It’s a beginner-friendly spot, but with 4 ft and a long period, it’s still gonna be fun for all levels.
The week after that, on the 1st of August, the Saturday morning also looks promising. We’ve got 4 ft from the S again, period 11 seconds, and clean cross-offshore wind. The energy is strong (681). It’s a solid option, but the Tuesday is the real gem.
A couple of late warnings: around the 30th and 31st of July, the swell gets bigger—6 ft to 7 ft—but the wind is onshore or rainy, and the quality drops. That’s messy, choppy stuff. Not our day.
So to wrap it up: the first week and a half is a bust. Then you get a few small clean days, then Tuesday the 28th is the absolute standout. After that, the 1st of August is a good backup. Don’t waste your energy on the rest.
Rusty.

Information about the Praia do Aventureiro Surf forecast

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Praia do Aventureiro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
