The Lowdown
G’day, Rusty here. Lookin’ at the next couple of weeks for Trestraou, and honestly, it’s a bit of a mixed bag. We’ve got some swell on the horizon, but the wind is gonna be a constant battle. The water temp is about average for this time of year, which is fine.
The first decent pulse comes in on Sunday, August 30. We’ve got a 5ft swell from the west, with a 9-second period bumpin’ through. The wind is a moderate offshore from the southwest, so the morning session is actually clean. There’s moderate wave energy (371) pushin’ in, but it’s not a world-beater. The surf is just surfable, nothing to write home about.
Monday, August 31, sees a big jump in size. The swell hits 8ft from the west, with a period of 10 seconds, and the energy is gettin’ solid (1232). But the wind is a fresh cross-shore from the WNW, and it’ll be lumpy and choppy. Not great. Tuesday morning, September 1, the wind backs off a bit to a gentle breeze from the WSW, and the swell drops to 4ft. It’s a cross-offshore wind, so it’s clean, but the wave energy is a weak 281. It’s surfable, but ordinary.
Things get a bit interesting on Saturday, September 5. The morning is glassy – a slight air from the southwest, which is a major positive. The swell is 6ft from the WNW with a 11-second period, a proper groundswell. The energy is moderate (643). This is the standout of the first week. Clean, decent size, and a long period that’ll wrap in nicely. Crowds are possible here, so get in early.
The second week has a few moments. Thursday, September 10, the afternoon glass off again with a light breeze from the ENE. The swell is a small 4ft from the west with an 8-second period, but it’s glassy. The wave energy is low (218), so it’s a longboard or a funboard session. Then, the real one to watch is Friday, September 11. The morning brings a 7ft swell from the west with a 12-second period, a very long period groundswell. The energy is strong (1277). The wind is a moderate offshore from the southwest, so it’ll be clean. This is the best of the whole run. It’s a big swell, but over 8ft it’s for experts only, and 7ft is in that sweet spot for experienced surfers. The long period will make it a bit straight at the beach, but it’s definitely worth a paddle.
Saturday, September 12, gets a bit wild. The swell is 10ft from the west with a 10-second period, but the wind is a fresh breeze from the west, and the afternoon is a near gale at 31 mph. Too big and too messy for a paddle. Kite surfers might be having a field day, but for us, it’s a no-go.
The rest of the second week is a write-off with smaller swell and cross-shore winds. No real standouts. So, to sum it up: the best windows are Saturday morning, September 5, and Friday morning, September 11. The 11th is the real gem, if the forecast holds.
Rusty.
