The Lowdown
Alright folks, Rusty here with a look at what’s on the cards for the Tramandai Pier (Platforma) stretch over the next couple of weeks.
Honestly, it’s a bit of a slow grind to start. We’re looking at a few days of marginal conditions before anything really gets going. The water is sitting at 59.9°, which is about 2.3° colder than normal for this time of year, so you’ll want a decent steamer if you’re paddling out.
Sunday the 13th kicks off with a small 3.9ft S swell, but the period is a short 7 seconds, giving the waves that weak, crumbly feel. The combined energy is only 234, so it's pretty weak. Wind is a cross-offshore from the SW, which will keep things clean, but the overall vibe is just marginal – a bit of a shoulder-hopper. That afternoon turns messy with onshore wind. Monday 14th is more of the same, small S swell with light cross-shore wind, but again, nothing to write home about. The energy stays under 340.
Tuesday morning 15th is the first flicker of hope. A 3ft S swell bumps up to a 10-second period, giving the waves a bit more push. The combined energy climbs to 323. A clean WSW cross-off breeze means it should be rideable and tidy. The surf is small, but clean lines for the log or a fun mid-length. That afternoon the wind swings and chops it up again.
Wednesday 16th sees the swell pick up. The morning has a 5.6ft S swell with an 8-second period and cross-off wind – clean, but still a bit weak in the period. Energy jumps to 727, so there’s some moderate grunt there. The afternoon builds to 6.6ft with a 10-second period, and energy surges to 906. This is a proper moderate swell. The wind goes cross-shore, so there’s a slight chop, but the size and period will push through. This could be the best session of this first week, but it’s not a clean sheet.
Thursday 17th is a write-off. NE winds are cross-on at 15 to 19 mph, making for lumpy, choppy conditions. Don't bother.
Friday 18th is small again, and the wind is on it. Saturday 19th the swell drops right off – only 1.6ft to 2.3ft – with poor onshore wind.
Sunday 20th we see a pulse of ENE swell at 5.9ft, but with a period of just 6 seconds, it's messy windswell. Onshore wind from the E makes it a write-off. The afternoon gets bigger at 7.5ft, but the wind goes straight onshore. That's kite-surf territory, not a great paddle.
Now, Monday 21st is where things get interesting, but it’s a week and a day out. The morning sees a solid 8.2ft ENE swell, but with a 9-second period. The combined energy hits a massive 1975 – that’s strong energy. The wind is light onshore from the ESE, so the wave quality will be questionable. It could be a powerful, messy beast. The afternoon drops to 6.9ft E swell with a cross-shore wind, which cleans it up a bit, but still energy over 700. If the wind plays ball, there could be some serious grunty waves, but it’s a long-range call.
Tuesday 22nd holds some size at 5.6ft with a 9-second period, but the wind is cross-on, keeping it chunky. Wednesday 23rd drops back to 3.9ft and is messy.
Thursday 24th is a tease. The swell is 4.6ft from the S, but with a 12-second period – that’s a proper groundswell. Energy is 720. The problem is the wind is cross-on from the NE, and in the afternoon it turns ENE. So you have a good quality swell being ruined by the wind. It’s frustrating.
Friday 25th is small again with a long-period groundswell, but the wind is onshore.
Then, Saturday 26th is a real highlight on the horizon. It’s small – only 2.6ft – but it’s a long-period S groundswell at 11 seconds. The best part? The wind is glassy. A light NE breeze, almost nothing. The combined energy is 208, so it’s weak, but for a log or a fun single-fin, those clean, glassy lines will be perfect. This is the standout session if you want a clean, cruisy morning.
Sunday 27th brings back some size. The morning has a 5.6ft S swell with a cross-off wind – clean and punchy. The afternoon jumps to 8.2ft S swell with a 10-second period and energy at 133
