The Lowdown
Alright folks, Rusty here. Let's take a hard look at the local surf scene. We've got a long 16-day window ahead, but to be honest, it's looking pretty grim. The first proper surfable conditions don't show up until well into the second week, so prepare for a long, flat spell.
The water temp is sitting at 65°F at the start, which is pretty much bang on normal for this time of year, so no complaints there, but you won't be needing a thick wetsuit for the first week because there's nothing to paddle into.
The pattern is dead flat with tiny, wind-chopped waves or no waves at all for the first week. The only real blip of hope comes out of nowhere on Wednesday, August 5th at Barra da Lagoa. Early morning we get a glassy surface with a 2ft swell rolling in from the SSE. The period is 10 seconds, the combined energy is a moderate 114 (moderate wave energy), and with a light westerly breeze making it glassy, this is the first real chance of the outlook. The swell direction is coming from the SSE, which is OK, but the optimum for this spot is ENE, so the banks might not be doing their best work. Still, it's the best on offer for a solid week.
After that, it's back to a long run of nothing until the 7th of August. On Friday, August 7th, we get a carbon copy of the 5th – another early morning glassy session with a 2ft SSE swell, 11-second period, and a combined energy of 107 (moderate wave energy). The wind is glassy from the SW. This is a standout only because everything else is so poor. The waves will be small, but clean.
Then, the outlook gets a bit more interesting towards the very end. On Tuesday, August 11th, the swell jumps up to 3ft from the ESE, but the period is a short 7 seconds. The wind is a strong cross-offshore from the S at 16 mph, so it will be clean, but that short period means the waves will be weak and crumbly. The combined energy is 123 (moderate wave energy). This is a bit of a wildcard – clean, but not great shape.
The final highlight is on Thursday, August 13th (that's next week). Early morning we get a glassy 2ft swell from the SSE, but the period is a very long 13 seconds, dropping to 16 seconds in the afternoon. The combined energy hits 179 (moderate wave energy). That's a proper groundswell pulse. The caveat here is that a long period SSE swell at a beach break like Barra da Lagoa can be a bit too straight and closed out. It might be better on the edges or if there's a sandbar working. The wind stays glassy in the morning, then goes cross-offshore from the S at 9 mph in the afternoon, so it'll be clean all day.
Honestly, if you're desperate, the 5th and 7th of August are your best bet for a tiny, clean surf. The 13th has more potential but is a week away and the long period might not play ball at this beach break. If the swell stays on the small side, it could be a fun beginner wave. The crowd profile at Barra da Lagoa says it's "often" busy, so even with this small stuff, expect company.
For the rest of the 16 days, it's a total write-off. There's no point even looking at the charts until that 13th of August window.
Rusty.
