The Lowdown
G'day, Rusty here. Let's have a look at what's cooking for Praia do Aventureiro over the next couple of weeks. It's a bit of a mixed bag, but there's a window of genuinely good surf if you're an experienced surfer.
The main pattern is a solid pulse of south swell arriving late in the week, with the standout being Wednesday morning, 26 August. That morning you're looking at a clean 5 ft swell from the S, and the wind is dead calm – glassy as. The wave energy is strong (1365), and with a 12-second period, it's a proper groundswell. This spot is a point break, so that long period will wrap in nicely. It's not a beginner wave at this size (over 5 ft), but for anyone with a bit of experience, that's the session to aim for. The water temp is about average for the time of year.
Tuesday, 25 August, is a write-off. You've got 7 ft to 7 ft southerly swell, but the onshore wind and questionable tides make it a waste of time.
Friday, 28 August, sees the swell drop quickly. Morning has 3 ft from the S, but it's weak (708) and still borderline. By the afternoon it's down to 3 ft (321) and just poor.
From Saturday, 29 August through to Monday, 31 August, we bottom out. The swell goes tiny and short period (8-9 seconds), with very low energy (160 or less). High pressure sets in with light winds, but there's just nothing to ride. That's four straight days of flat to near-flat conditions.
Heading into the new week, things perk up a little. Wednesday morning, 2 September, brings 5 ft of S swell (441) with light onshore wind. Not great. But Wednesday afternoon and all-day Thursday, 3 September, see glassy conditions return with 4 ft to 5 ft southerly swell (375-379). The period is 9-10 seconds, so it's a bit shorter, but for a mellow session in clean conditions, it's surfable.
Looking further ahead to the second week: Saturday, 5 September, has a 6 ft pulse from the SSE (874) with a clean offshore wind, but the period is 11 seconds and the wind is moderate, so it's promising but less certain. Sunday and Monday ease off again.
So, the pick of the entire 16 days is Wednesday, 26 August morning. Glassy 5 ft south swell at a consistent point break with solid energy. If you can surf that size, get on it. The other window is the glassy afternoons on 2 and 3 September for a smaller, more relaxed paddle.
Stay stoked,
Rusty

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.
