Alright crew, Rusty here with the lowdown.
First thing to know: the water’s running real cold for this time of year, about 3°F colder than usual, so you’ll need a thick suit.
The first surf worth paddling for is on Thursday the 9th, but it’s rough. We got 3ft of short-period ESE swell with a nasty cross-on breeze at 12 mph, making it choppy and messy. The energy is weak (128), so I’d wait.
Friday the 10th is much better. Friday morning is glassy with a light W wind, and a clean 2ft ESE swell. The period is 14 seconds, proper groundswell, so the shape will be there even if it’s small. It’s clean and glassy – perfect for a longboard. Friday afternoon, the swell bumps to 3ft with a 12-second period, a light cross-off S wind at 6 mph, and the energy hits a moderate 445. It’s clean, but the wind is a little off, so it’s a good option.
Saturday the 11th is a tough one. Morning has 5ft of ESE swell at 13 seconds, but with a cross-shore wind and rain showers, the surf is marginal. The energy is decent (700), but it’s not going to be pretty. The afternoon drops to 3ft and gets messy.
Sunday the 12th is the one. Sunday morning is the standout. We get 5ft of ESE swell with a 12-second period, and the wind is glassy from the SW at just 3 mph. The energy is strong at 759, and the conditions are forecast to be very good. This is going to be clean, with nice lines. The size is into the intermediate zone, but it’s manageable. The swell direction from the ESE is right on the money for the optimum here (ENE). This is the best of the whole forecast.
Sunday afternoon, the wind swings to the S at 16 mph, and the swell drops to 4ft with a shorter 9-second period. Leave it.
Monday the 13th is a total washout with strong S winds and small, weak surf.
Tuesday the 14th morning is workable. We get a clean 5ft from the SSE with a 10-second period, and a light cross-off NW wind at 6 mph. The energy is moderate (360). It’s okay, but not as good as Sunday.
From Wednesday the 15th right through to Thursday the 24th, there’s a big gap of several days with no swell, just flat and choppy conditions. Then on Friday the 24th, a pulse of 5ft SSE swell shows up, but with a short 8-second period and a cross-on wind, it’s going to be a messy, blown-out mess. Not worth it.
So, the real highlight is Sunday morning, July 12th at Barra da Lagoa. Glassy, clean, 5ft of groundswell, and strong energy. Get on it.
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 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.
