The Lowdown
Alright, ol' mate Rusty here, and let's have a look at the charts for Praia do Aventureiro. This is a pretty consistent little point break, so it's got some character, even if the waves aren't all-time. The water's sitting at a touch warmer than usual for this time of year, about 73°, nothing too crazy.
Right off the bat, we've got a bit of a mixed bag. The first couple of days are small but clean. Tuesday the 15th has some knee-high 3-foot waves from the south with an 11-second period, and a light cross-offshore breeze. It's not gonna blow you away, but you'll score a few fun ones, and with the wave energy sitting at (287), it's pretty weak. The crowds will be there sometimes, but it's nothing a patient surfer can't handle. Wednesday morning the 16th sees a slight bump to 4-foot, but the period drops to a short 8 seconds, making for a bit of a lumpy mess, though the offshore wind makes it rideable.
Now, Thursday the 17th through Saturday the 19th is a total write-off. We've got onshore winds blowing straight into the face, up to 19 mph, and the swell gets messy and lumpy. That's a few days you can sleep in or go find something else to do. The wave energy jumps into the moderate range (between 346 and 447), but it's all wind chop.
The real highlight of this whole outlook is Sunday the 20th, first thing. We get a glassy, dead-calm morning with a solid 6-foot swell from the east-southeast, and a wave energy reading of (779) – that's a proper pulse. It's a little under 8 seconds period, so it's a bit of a wind swell, but with glass-off conditions at a point break like this, it's going to be peeling nicely. It's on the bigger side, but for the experienced crew, this is the standout session of the fortnight. Get out there early because the afternoon onshore kicks in.
After that, we settle back into small, clean conditions for a few days. Monday the 21st is a no-go with onshore wind, but Tuesday the 22nd morning is glassy with 3-foot waves and really weak energy (130). The 24th and 25th also have some glassy windows with waist-high 4-foot and 3-foot waves, but the energy is low. It's a good time for a longboard or a foiler.
Then, hold onto your boardies for the end of the month. Monday the 28th sees a serious ramp-up in size. We're looking at 8-foot waves from the south with a long 12-second period, and a massive wave energy reading of (1423). This is expert-only territory – it's way too big for beginners. It's a little tricky because the wind is a light cross-onshore, which might put a bit of a crinkle on the face at a point break like this. However, the period is long enough that the sets will have proper power. The 30th of September also cleans up nicely in the afternoon with a light offshore wind and 5-foot waves, making for some very good conditions again.
So to sum it up: the best wave of the next two weeks is undoubtedly the glassy Sunday the 20th morning session. The second standout is the big, powerful swell on the 28th for the experts only. Everything else is small and clean, or blown out.
Rusty, signing out.

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.
