The Lowdown
Alright, Rusty here for the Tramandai Pier (Platforma) in imperial.
We’re looking at a slow start with a long dry spell of nothing worth paddling for. From now through Wednesday the 19th, it’s just marginal. Swell’s only about 3ft from the ENE with a short 8-second interval, combined energy weak (204). Not worth suiting up. Thursday the 20th through Friday the 21st is straight-up poor—strong onshore and cross-shore winds, lumpy chop. That’s a gap of several days with no real surf.
Saturday the 22nd shows a pulse. Clean 6ft S swell with 9-second period, cross-offshore wind from the WSW, combined energy moderate (540). Still just marginal, but it’s a step in the right direction.
Sunday the 23rd is the clear standout. Solid 7ft to 8ft S groundswell, period hitting 12 seconds, clean cross-offshore wind all day, and combined energy jumping to 1215 in the morning and 1686 in the afternoon – that’s strong. The S swell matches up well with the break’s optimum (SSE), but remember it’s a beach and pier setup. Long-period groundswell at 12 seconds can make the waves break a bit straight here. Water temp is about 61°F, right around normal for the season.
Monday the 24th looks messy. Swell hits 8ft with a very long 14-second period from SSE, but cross-onshore wind ruins the face. Combined energy is massive at 2725 – that’s more of a kite-surfing day than a clean surf session.
Tuesday the 25th backs off again, waist-high SSE swell, cross or light cross-onshore, nothing special.
Wednesday the 26th morning is a gem. Glassy calm, zero wind, a clean 4ft SSE swell with 11-second period, combined energy 398. For a few hours it’ll be clean and fun. Afternoon turns cross-onshore and choppy again.
After that, it’s marginal to poor through the rest of August and into early September. There’s a glassy 2ft morning on Friday the 28th, but it’s weak. Sunday the 30th afternoon shows some potential: 5ft ENE swell with light offshore west wind, 9-second period, combined energy 501 – a decent little clean-up session.
The long-range standout is Thursday the 3rd of September. Morning has a 7ft E swell with offshore west wind, but only a 6-second period – weak and bumpy. Afternoon gets wild: the swell is predicted at 10ft from the ENE with 8-second period. That’s too big and short-period for this break – only experts, and even then it’ll be a messy beast. Combined energy hits 1147.
Best of the whole 16-day run? Sunday the 23rd of August with that solid 7ft-8ft S groundswell and clean cross-offshore wind. Circle that one. The glassy Wednesday the 26th morning is your backup for smaller, glassy fun. Everything else is a gamble.
Rusty.
