The Lowdown
Alright crew, Rusty here with the lowdown. Gotta be straight – the outlook for Barra da Lagoa over the next couple of weeks is pretty grim. We're looking at a long stretch of flat, weak, or just plain messy conditions. It’s a tough run, and the forecast shows very little to get excited about for a while.
The only time we see any real pulse of energy is around Monday the 14th of September. The morning brings a small 4ft swell from the SSE with a short period of 8 seconds, carrying moderate energy (149). It’s not much, and the cross-off wind from the SSW at 12 mph will keep it clean enough for a beginner session. The water is sitting at 64°F, which feels a bit colder than usual for this time of year. That afternoon the swell drops back to 2ft, but the period stretches to 11 seconds, giving it a little more shape, and the energy bumps up to 221. It’s still just ordinary, but with a light breeze, it’s the closest we get to something rideable. Tuesday morning the 15th is similar – 3ft from the SE at 9 seconds, clean under light SSW winds. That's really the only stretch worth mentioning, and even then, it’s nothing to write home about.
After that, it’s a brutal run of tiny or non-existent surf. Wednesday the 16th is flat. Thursday the 17th is flat with glassy conditions, but no waves. Friday the 18th has a 3ft SSE swell but cross-shore winds mess it up, and then it’s back to near-flat through the weekend and into the next week. The 19th of September has a glassy morning with 2ft of SSE swell, but the wind turns onshore in the afternoon. From the 20th through to the 28th, we see only tiny dribbles of 1ft or less, often with poor wind, and many days are completely flat.
To be honest, if you're determined to get wet, the Monday and Tuesday of the 14th and 15th are your only real shot, and even then it’s a marginal beginner session. The rest of the period is a write-off for paddle surfing. Given the lack of quality and the persistent onshore or cross-shore winds, this setup actually looks more interesting for kite surfing than paddle surfing during the breezy afternoons.
The area is usually fairly consistent, so a blank run like this is a bit unusual, but sometimes you just have to wait it out. Forecasts can change, so don't lose all hope.
