The Lowdown

Gap at the start, folks. Don’t even bother looking at the ocean until Wednesday the 5th. It’s flat and messy through Tuesday the 4th, with weak, junky SE windswell and onshore junk. Water temp is sitting at 65°, which is pretty much normal for this time of year – nothing weird going on there.

First real chance to get wet is Wednesday morning, the 5th, at Barra da Lagoa. It’s not pumping, but it’s clean. We’ve got a glassy 3ft of SSE swell, period around 10 seconds. Combined energy is only 169 – weak. It’s small and ordinary, but if you’re jonesing, it’s a paddle. The afternoon goes downhill with a cross-on breeze, so make it a dawn patrol session.

Thursday the 6th is a write-off. The swell drops, the wind goes cross-shore, and it’s just poor. Friday the 7th through Monday the 10th is a flat, blown-out mess. Clean cross-off winds, but there’s simply nothing to ride. The ocean is doing nothing. You’re looking at a solid four-day drought there.

Tuesday the 11th is still flat. Wednesday the 12th sees a slight bump, but it’s short-period ENE slop – 3ft at 6 seconds. That’s windswell junk, and the energy is only 67. Forget it. Thursday the 13th and Friday the 14th are also flat. Another three days of nothing.

Now, here’s the one that’s got my attention. Saturday morning, the 15th. It’s a week out, so don’t book a flight yet, but the models are showing something real. Barra da Lagoa has a clean 7ft of SSE groundswell, with a 13-second period. Combined energy is 1657 – that’s strong. This is the standout of the whole window. The wind is light and cross-off, so it should be glassy. This is a proper winter swell. It’s big, though – over 8ft is expert-only, and this is 7ft, so it’s still in the experienced surfer range. Beginners, stay on the beach. The long period means it’ll be lined up and powerful. This is the one to circle on the calendar.

The afternoon of the 15th gets messy with an onshore ENE breeze and a short-period drop-off. Not worth it.

Sunday the 16th is howling cross-on with 25 mph winds. Garbage. The 17th has some clean leftover swell – 3ft at 12 seconds – but it’s crossed up and just ordinary. The 18th and 19th have some inconsistent, small SE pulses, but nothing that gets the heart rate up. The energy is moderate at best, and the wind is all over the place.

Bottom line: There’s a big gap up front, a long flat spell, and then one proper day – Saturday the 15th. That’s your wave. Everything else is a struggle.

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.

If you surf the same spot (Barra da Lagoa) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
