The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the radar for Praia do Aventureiro. It’s a bit of a mixed bag over the next couple of weeks, so let’s get into it.
The first few days, honest truth, are a write-off. Tuesday and Wednesday are looking pretty average at best. We’ve got some small, jumbled swell and cross-onshore winds making a mess of things. It's not going to be worth paddling out unless you’re just desperate for a splash. The wave energy is weak, sitting around 304 to 632, and the swell is short-period stuff. Not good.
We have to wait until Thursday morning for the first real glimmer. The wind goes glassy with the swell coming from the south at 3ft and a period of 12 seconds. It won't be big, but it will be clean. That’s the kind of morning where you can get a few fun ones without the chaos. The energy is moderate at 363.
The following weekend stays pretty quiet. Small surf and ordinary conditions rule the roost. But then, Sunday the 13th, things start to light up. We see a pulse of south swell pushing 6ft early in the day with that gorgeous glassy morning. The energy jumps to a strong 723. This looks like the first really good window. The only problem is the wind is forecast to swing onshore and get raw in the afternoon, so you gotta be an early bird to make the most of it.
That swell sticks around for Monday and Tuesday, but the winds stay messy. There’s plenty of energy in the water, with readings up to 1739, but the cross-onshore chop will make conditions pretty tough. If you’re an experienced surfer, it’s worth a look, but the surface is going to be lumpy.
We get another reprieve on Wednesday the 16th morning. The wind goes glassy again with 4ft of south-southeast swell at a 12-second period. It’s cleaner, light, and offers some fun, user-friendly waves.
After that, get ready for a rough patch. From Thursday the 17th through to the end of the forecast, it looks poor. The winds stay strong and onshore, the swell drops off and becomes disorganised, and the energy sinks back down. The period even drops below 8 seconds at times, which means super weak, choppy waves. There are days where there’s just nothing on offer, and you’re better off doing something else with your time.
There’s a tiny blip on the 22nd with a offshore wind and 4ft of clean-ish swell, but it’s not going to be anything special. It’s a long stretch of blank days, so patience will be key. For a spot like this, it’s just part of the rhythm. The standout sessions are clearly the glassy mornings on the 13th and the 16th. That’s when it’ll be worth the effort.
So, to sum it up: we’ve got some rough starts, and a long flat spell at the end. But there are a couple of days that should get the heart rate up. Keep an eye on those Sunday and Wednesday mornings. This is Rusty, signing off.

Information about the Praia do Aventureiro Surf forecast
The above surf forecast table for Praia do Aventureiro provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.
