The Lowdown
G’day, it’s Rusty here. Let’s cut to it – the next couple of weeks at Barra da Lagoa are looking pretty average to be honest. We’ve got a stretch of days with very little on offer, especially through the middle of the period. If you’re keen, there’s one standout window coming up that’s worth keeping an eye on, but it’s a patience game. The water temp is running about average for this time of year, so nothing weird there.
Right now, Wednesday morning is actually the cleanest we’ll see for a bit. It’s glassy with a slight air, and there’s a small 3ft SSE swell rolling in with a 10-second period. The combined energy is weak at 118, so it’s not going to blow you away, but it’s surfable and clean. The swell direction is coming from the SSE, which is not quite the ENE optimum for this spot, so it’s a bit ordinary. Still, for a quick splash on a longboard, it might be your best bet for the next few days because the afternoon drops off and the rest of the week turns to rubbish.
Thursday and Friday are poor. The wind switches cross-shore and picks up, with rain showers on Friday afternoon. Wave heights are tiny or onshore, and energy is negligible. Saturday’s a write-off with no swell to speak of and a fresh breeze, though it’s clean. Sunday the 13th sees a bit more size – 7ft from the SSE with a 10-second period and moderate energy (855) – but it’s cross-shore and choppy, making it messy and not worth your time unless you’re desperate. By Monday the 14th, it’s smaller and still onshore.
The standout is Tuesday the 15th morning. The wind goes light cross-off from the SSW, and the ocean cleans right up. There’s 4ft of SE swell with a 9-second period and moderate energy at 176. It’s not big, but it’s clean and surfable, and after all the junk, that’s a win. Given the crowd profile is “often” here, don’t be surprised if a few others have the same idea, but the clean conditions make it worthwhile. This is the best on offer in the whole run.
After that, the middle of the month is pretty bleak. From the 16th through the 19th, it’s mostly small, onshore, or just flat – no real surf to speak of. There’s a brief blip on Sunday the 20th with 4ft SSE swell, but the wind is cross-onshore and choppy, so it’s poor. The 21st morning is glassy again with a tiny 3ft SSE swell and weak energy at 78 – surfable but nothing special.
The last few days of the period, from the 22nd to the 24th, are small and messy, with the swell fading to almost nothing by Thursday. Honestly, if you’re flexible, the Tuesday the 15th morning is the one to chase. The long-range stuff is promising but less certain, so keep an eye on it. Otherwise, it’s a quiet stretch – a bit of a flat spell, but that’s how it goes sometimes.
Signing off – Rusty.

Information about the Barra da Lagoa Surf forecast
The above surf forecast table for Barra da Lagoa provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Barra da Lagoa can be found by selecting the local surf guide option on the grey menu. Our Barra da Lagoa surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

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 Barra da Lagoa 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.
