The Lowdown
G’day, it’s Rusty here.
Look, I’m going to be straight with you: the next couple of weeks are looking pretty grim for a proper paddle at Triggs Beach (Adelaide). We’ve got a long stretch of tiny, weak swell and mostly onshore or cross-onshore winds messing things up. If you’re desperate for a splash, there are a few moments where the ocean goes glassy, but you’ll be surfing ankle-biters at best. The water temp is sitting at 58°F, which is about normal for this time of year, so nothing weird there, just cold.
The first real chance of anything surfable doesn’t show up until the morning of Tuesday the 26th of August. We’ve got a bit of a push from the northwest, with swell around 3ft but a period of only 4 seconds. That’s just windslop, and with a strong 25 mph westerly blowing straight onshore, it’s going to be a messy, blown-out mess. The combined energy is a weak 35, so don’t get your hopes up. This is more of a kite-surfing day than a surfing day. The wind hangs in from the west through Wednesday the 27th, and while the swell bumps up slightly to 4ft from the WSW with a period of 6 seconds and energy of 87, it’s still onshore junk. The conditions are still poor; the wind is just too strong and from the wrong direction for any clean waves.
After that, it’s another flat spell right through to the end of the month. There’s a glimpse of some cleaner conditions on Friday the 29th of August with a cross-offshore breeze from the south, but the swell is a puny 0.3ft. It’s pretty to look at but there’s nothing to ride. The same story continues into the first week of September.
The best of a bad bunch might be on the morning of Monday the 1st of September. We have glassy conditions with a light offshore from the NNE, and a tiny 0.3ft of south swell with a long 17-second period. Combined energy is only 6, so it’s weak, but at least the surface will be clean. It’s not worth getting out of bed for unless you just want to sit on your board and enjoy the calm. There’s a slightly better window on Wednesday the 2nd of September, with a glassy morning and a 0.3ft swell from the southwest at 15 seconds. Again, it’s flat, but it’s clean.
So, honestly, this is a lean 16-day run. Triggs is as inconsistent as it gets, and with this lack of swell, it’s not looking like it’ll turn on. It’s sheltered from the good WSW swell direction, and we’re not getting any of that. Keep the board in the car, but maybe just for the drive. The ocean will come back; it always does.
Rusty.
