The Lowdown
Alright folks, Rusty here. Let’s have a good look at what’s coming up for Praia da Baleia. We’ve got a mixed bag over the next couple of weeks, but there are some definite windows of clean waves to get excited about. The water temp is sitting about average for this time of year, so nothing out of the ordinary there.
We kick things off on Wednesday, 2nd September, with a morning session that’s looking tidy. The swell is a clean 4ft from the south with a short 8-second period, but the wind is glassy and the energy is moderate (400). It’s a good start for the week, especially for beginners as the size is manageable. The afternoon gets a bit lumpy though, with the wind picking up onshore and the swell jumping to 6ft.
Thursday the 3rd sees a bit more size but the wind isn’t doing us any favours. The morning has a cross-shore breeze with a 5ft SSE swell and a longer 11-second period, which brings some decent energy (547). The afternoon gets cross-onshore, making it a bit of a struggle to find a clean face.
Friday the 4th is a real gem. The morning is completely glassy, calm as can be, with a 3ft SSE swell and an 11-second period. The energy is lighter (315), but the conditions will be perfect for a long, cruisy session. This is a standout for the week if you’re after clean, small waves.
The weekend takes a turn for the worse. Saturday the 5th and Sunday the 6th are dominated by rain and onshore winds, with the swell getting messy and short-period. The energy drops right off (lowest at 99), and the swell is a mushy 2ft to 6ft, but it’s poor quality. I’d be giving the weekend a miss.
Monday the 7th is still a bit average with light rain and cross-onshore winds, but the swell holds at 5ft from the south with a slightly better 9-second period. It’s marginal at best.
Now, Tuesday the 8th is where things get interesting. The afternoon is a real standout. The wind goes glassy, the swell is a solid 5ft from the south with a long 11-second period, and the energy is strong (592). The conditions are clean, and the longer period will give the waves some punch. This is a great session for intermediate surfers.
Wednesday the 9th and Thursday the 10th hold some promise. Thursday morning especially is looking clean with a cross-offshore breeze and a 5ft east swell with an 8-second period. The energy is solid (681). The afternoon on Thursday goes glassy again with a 5ft ESE swell, making for another clean, fun session.
The following week starts to fade. Friday the 11th has a glassy morning with a 5ft ESE swell and a 9-second period, but the energy is moderate (381). The weekend of the 12th and 13th is small and messy, with the wind turning onshore on Sunday and the swell dropping to below 3ft. There’s a three-day gap here with no real recommendations.
The real highlight of the entire forecast lands on Tuesday, 15th September. The morning is glassy, completely calm, with a 7ft SE swell and a 9-second period. The energy is massive (1269) – that’s strong, powerful surf. This is only for experienced surfers as it’s over 8ft, but the conditions will be excellent, with clean, glassy waves. The afternoon on the 15th and the morning of the 16th also hold very good conditions with glassy winds and 6ft SE swell, perfect for those who are comfortable in bigger surf.
The final day on the 17th is a nice way to wind down, with a glassy morning and a 4ft SE swell with a long 11-second period. The energy is moderate (424), but the clean conditions will make for a fun, easy session.
Rusty out.
