The Lowdown
Alright, lemme give it to you in feet and miles per hour. This is Rusty again for Praia do Aventureiro.
First week is a total dud. From Saturday the 18th through Thursday the 24th, it’s mostly poor surf – tiny waves, cross or onshore breezes, and not much to ride. There’s a couple of so-so moments (Monday afternoon the 20th and Thursday morning the 23rd), but nothing worth paddling out for.
The first real highlight is Saturday morning the 25th of July. Swell hits about 4ft from the SSE, with a 9-second period, and the wind is light cross-off out of the SW – clean as a whistle. The energy is moderate (355). This is a point break, beginner-friendly, and it breaks consistently. Crowds are possible, so you might have company. Water temp is about 71°, which is normal for this time of year.
Next up is Monday morning the 27th of July. Swell again around 4ft, but from the ESE, period 7 seconds, and the wind goes glassy – dead calm from the WNW. That’s about as perfect as it gets for a clean session. Energy is moderate (349). Short period, but with glassy conditions, it’ll be fun for everyone.
After that, the forecast gets messy again. The 28th and 29th have onshore winds and marginal surf. The 30th is ordinary. The 31st is poor. Then on the 1st of August, there’s a bigger swell (6ft SE, 10s, energy 889), but the wind is cross-on and the comment says marginal – tide issues likely. The 2nd of August morning is similar: 6ft SE, 10s, energy 889, but cross-on wind and a marginal note. Not a standout, but worth checking if the wind changes.
So your best days are Saturday the 25th and Monday the 27th. After that, it’s a long wait. The point break is reliable, but the first week is a wash. Stay patient.

A general guide to surfing at Praia do Aventureiro can be found by selecting the local surf guide option on the grey menu.

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.
