The Lowdown
Alright folks, Rusty here. Let’s talk about the next couple of weeks at Praia da Boraceia.
The surf this week starts off with some size, but it’s going to take a few days for things to clean up. The water is sitting at a touch warmer than average for the time of year, about 71°, so it’s pretty comfortable out there.
Monday the 24th has the most swell with Southerly 7ft waves pushing through, but the wind is a light cross-onshore and there’s a bit of rain around, so the conditions are messy. The combined swell energy is strong at 1779 (moderate to strong), but the onshore breeze is killing any real quality for a paddle. That afternoon stays similar.
We finally get a window on Tuesday the 25th morning. The wind swings NE, going cross-offshore, and those Southerly 6ft waves have a solid 14-second period behind them, giving them some real push. Combined energy is still a healthy 1256 (moderate). This is the standout session of the week – clean and surfable. By Tuesday arvo, the wind goes glassy from the SSE as the swell drops to 5ft, making for some very nice, clean afternoon waves.
Wednesday the 26th morning is looking excellent for experienced surfers. It’s glassy, the swell is 4ft from the SSE, and that period stretches out to a very long 16 seconds. That’s proper groundswell, which means long waits between sets but plenty of power. The combined swell energy reads 1189 (moderate). This will be best for a longboard or a step-up, and the point will hold it nicely.
Thursday the 27th morning is another gem. Glassy conditions, a W wind, and a clean 6ft SSE swell with 14-second period. Combined energy is 1190 (moderate). This is right up there with Tuesday for quality.
After Thursday, the size backs off noticeably. Friday the 28th still has some clean 6ft waves in the morning with no wind at all – glassy perfection – but the period drops to 8 seconds. It’s fun, but not the same grunt. The combined energy is 688 (moderate). That afternoon drops further.
From Saturday the 29th right through to the end of the first week, we’re looking at a big gap of small, weak surf. The swell height drops below 3ft and combined energy falls below 200 most days. Not really worth the paddle, unless you're on a foamie.
Moving into the second week, there’s a glimmer early on. Wednesday the 2nd of September morning shows a pulse of 6ft Southerly swell with 8-second period and glassy conditions. Combined energy climbs back to 777 (moderate). That’s the best bet in that stretch, but it's a shorter-period swell, so expect a bit more chop at the beach break. Thursday the 3rd drops off fast. The rest of the week stays small and weak, with only occasional waist-high options that are ordinary at best.
Because this spot is a beach break, those long-period swells we saw are prone to closing out a bit straight, but the good wind days will make up for it. Crowds are possible here, so keep an eye out.
So, to sum it up: Don’t stress about the slow spell at the end of this week or the middle of next. The standout sessions are Tuesday the 25th and Thursday the 27th – that’s where you want to be. The Wednesday the 26th morning is also a beaut for the experienced crew.
Rusty.

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 da Boraceia 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.
