Copacabana Surf Forecast and Surf Report

Alright, Rusty here. Let’s break it down.

We’ve got a slow start, then a few good windows, and a heavy run into the second week. The first real surf shows up Friday morning, the 28th of August, so the first couple of days are a write-off.

Friday morning, 28th August – Copacabana starts clean and glassy. A 4ft northwest swell, period around 7 seconds, with moderate energy (212). The wind is dead calm, so the surface is smooth. Good way to get the weekend started.

Saturday, 29th August – Morning is even better. Glassy again, with a 5ft northwest swell, period stretching to 9 seconds, and energy at 291 (moderate). The sets have more push. This is the pick of the early days.

Sunday, 30th August – Now we’re cooking. The morning is glassy, with a 6ft northwest swell, period hitting 10 seconds, and energy at 627 (strong). That’s the best combo of the week: clean, solid, and powerful. The afternoon shifts onshore, so get out early.

Monday, 31st August – The swell holds at 5-6ft, but the wind is more mixed – cross-onshore and onshore. Energy is still strong (480-635), but the quality drops. Still surfable, but not as clean.

From Tuesday, 1st September, through to Wednesday, 9th September, we hit a long flat stretch. The swell drops below 3ft, and energy is weak (under 100). The wind is a mix of glass and cross-off, but there just isn’t enough swell. A few 2ft to 3ft days, but they’re ordinary. A dry run.

Thursday, 10th September – Finally, something promising. The morning sees a 6ft swell from the NNW, period 8 seconds, and energy at 808 (strong). The wind is light cross-shore, so it’s a bit choppy but rideable. The afternoon bumps to 7ft, still from the NNW, but energy drops to 644 (moderate-strong). This is for experienced surfers – that size is pushing it.

Friday, 11th September – The standout of the entire forecast. Morning sees a 8ft NW swell, period 9 seconds, and energy at 1040 (very strong). The wind is light cross-onshore, so there’s some texture, but the power is massive. This is a big, powerful groundswell – only for experts. The combined energy reading is off the charts. If you’re advanced, this is your window.

So, the best bets: Saturday morning, 29th August, for the clean, fun-size waves, and Sunday morning, 30th August, for the best combo of size and glass. The real standout is Friday, 11th September – serious power, but only for the brave.

Keep an eye on that later window – it’s promising but not locked in.

Rusty.
