The Lowdown
Alright, folks, Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty grim for a proper surf. I’ve scanned the charts for our stretch of coast, and it’s a whole lot of waiting around, staring at a flat, lumpy ocean.
The target is Triggs Beach Adelaide, a sheltered reef spot that usually needs a decent west-southwest swell to get going. To be honest, for the entire 16-day window, there is not one single recommended session. Every single call is rated as poor surf conditions. That’s a rare and frustrating blank run for this area.
Right now, through the weekend, we’ve got nothing. There’s a tiny pulse of swell on Saturday the 8th, maybe 4ft, but it’s wind swell with a short, weak 5-second period, and a fresh northerly wind will have it all lumpy and cross-chop. Not worth paddling out for. The energy is weak too, at 64 to 77 on the combined scale. Sunday the 9th is worse, with a strong onshore flow and rain. It’s a write-off.
There’s a slightly bigger pulse early next week, starting Monday the 10th. The swell builds to 5ft with a 6-second period, but it’s still coming from the west and the winds are on it. The energy is moderate, hitting 166, but the wind is going to make it a messy, onshore mess. By Tuesday the 11th, the wind swings north and howls at 22-25 mph, which will just chop up that 6ft of swell. It’s not going to be any fun.
We then go through a stretch of tiny, weak swell and flat spells from around the 13th to the 18th. There’s a few days with barely a ripple, and the water temp is 57°, which is about normal for this time of year, not that you’ll be in it much. The highlight of this period will be the clean, glassy mornings with no swell at all. Great for a paddle, terrible for surfing.
The final two or three days of the outlook, around the 19th and 20th, show a slight increase in wind swell, but it’s from the north, not our ideal west-southwest. The period is a dismal 4 seconds, so it’ll be soft and weak. I wouldn’t get your hopes up.
So, there it is. A flat, blown-out, and uninspiring outlook. For anyone thinking of getting wet, it’s looking more like a kite-surfing week than a surfing one. The breaks will be all chop and no shape. It tends not to stay this poor for long, and forecasts can change, but for now, you’re better off polishing your board and waiting for the next proper swell.
Rusty, out.
