The Lowdown
G’day, I’m Rusty. Let’s cut to the chase – the forecast for Barra da Lagoa is a slow starter. The next week and a half is mostly flat, tiny, or blown out. There’s a real gap of quiet days from August 28th right through to September 2nd where you’ll be lucky to get a knee-high bump, and the conditions are ordinary. The water temp is sitting at 65°F, which is about average for this time of year.
The first real glimmer comes on Wednesday September 2nd, when a solid SSE swell pushes in at 8ft with a period of 11 seconds. The energy is strong (1324), but it’s cross-shore with a bit of chop, and the wind is cross-on – so it’s more for the experienced crew. That’s a big drop for a beginner. Then Thursday September 3rd morning cleans up nicely with a 6ft SSE swell, light offshore wind from the S, and clean conditions. The energy is moderate (616) and it’s a solid, rideable wave – but it’s not a standout.
The true standout, the best on offer, rolls in on Monday September 7th. Morning session sees a 8ft SSE groundswell with a long 14-second period, light offshore wind from the NW, and glassy clean conditions. The energy is pumping (1886). This is a proper swell, but at 8ft it’s pushing into expert territory – too big for beginners. The wind is clean, but the long period groundswell might make it break a bit straight at the beach, so watch for that. It’s a powerful, deep-water swell that’s well worth the paddle out. The afternoon is a bit windier but still clean, though the wind pipes up to 19 mph from the S. The rest of the second week fades into smaller, wind-affected surf or bigger onshore slop, so that Monday morning is your best bet.
