The Lowdown
G’day, Rusty here. Let’s cut straight to it. The next couple of weeks at Praia do Aventureiro are a mixed bag, but if you’re patient, there are a couple of proper windows hiding in there. The start is slow, with a lot of slop and onshore junk, but the back half of the period is where the real potential lives. Keep your eyes on the 23rd and the 25th through the 27th – that’s where the magic is.
Right now, Saturday the 15th is a write-off. We’ve got rain showers and a moderate breeze, and the swell is a messy 7ft from the SSE at 13 seconds, but the energy is all over the place – 1365 on the combined scale, which sounds big, but it’s not doing us any favours. The water’s sitting at 72°, which is a touch warmer than average for this time of year. Not a session to get excited about. Sunday the 16th is even worse – poor conditions and clean waves are a no-go.
The gap stretches through most of next week. Monday through Thursday is all marginal surf at best, with the odd glassy morning on Thursday the 20th but tiny, weak swell around 2ft and only 55 in the energy department. It’s not worth paddling out for anything meaningful. That’s a solid four or five days of nothing happening. Friday the 21st is still poor, with cross-off winds but clean lines – just no size to get your hopes up.
Saturday the 22nd starts to show a pulse. Glassy early, with about 4ft of S swell at 7 seconds, but it’s just “surfable” – nothing special. The afternoon goes to junk with the wind. But then, Sunday the 23rd is your first real standout. Morning is glassy calm, clean as a whistle, and we’ve got 6ft of S swell with a 12-second period, and the energy jumps up to 974 – solid, moderate-to-strong push. This one is a proper point break session, but note that this is a long-period groundswell, so it might be breaking a little too straight for the beach. Still, for a point, it’s going to be fun. The afternoon goes to chop with a 12 mph onshore, so you want to be out there early.
Monday the 24th brings more size, with 7ft to 8ft of S swell at 14-15 seconds. This is big – over 5ft, so it’s pushing into more experienced territory, and the energy is strong, hitting over 2000. But the wind is cross-onshore, so it’s going to be lumpy. Not the cleanest, but the potential is there for capable surfers.
Tuesday the 25th is the other standout. The morning is cross-onshore, but the afternoon is glassy with 7ft of S swell at 14 seconds and energy at 1721. For experienced surfers, this is going to be excellent – long period, solid size, and clean. This is the one to circle on the calendar.
Wednesday the 26th backs off a bit, with 6ft, still S but the wind goes cross-shore. Thursday the 27th comes back strong – glassy all day, with 7ft to 8ft of S swell at 10-12 seconds. The morning is very good, and the afternoon’s swing to the SSW keeps it clean. This is your other big window.
After that, the run fades. Friday the 28th has a morning glassy drop to 3ft, and then the whole weekend drifts back into the ordinary. By the 30th, it’s mostly poor, with small S swell and onshore junk.
So, bottom line: the first eight or nine days are a slog. The true standouts are the mornings of the 23rd and the 25th-27th. Big southern groundswell, long periods, and clean conditions if you time the tides right. Remember, the long-period stuff is best on this point setup, so keep it in mind. This isn’t a beginners' swell – it’s over 5ft and pushing past 7ft, so only go out if you’ve got the confidence. The energy is moderate-to-strong, so there’s plenty of push.
Crowds are possible here, especially when the surf’s firing, so get in early. If you miss the window, the rest of the fortnight is a non-event, but this place tends to stay in the game – forecasts shift, so keep an eye out.
Rusty out.

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.
