The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ over the next couple of weeks.
Straight up, Triggs Beach Adelaide is pretty much a write-off for the entire 16-day window. We’re looking at a long, long stretch of nothing good. From now through to about the 22nd of August, it’s mostly flat or just dribble. The only real bump in the road is Saturday the 22nd afternoon, where a 5.6ft swell from the NNW sneaks in, but it’s got a short period of 6 seconds and cross-onshore winds at 10 km/h, making for rough conditions. Plus, with moderate wave energy (198) and that cross-onshore chop, it's not going to be clean. Honestly, that looks more like a kiter’s setup than a paddle surfer’s.
Even when there's a tiny pulse, the wind is usually junk or the swell is too small or too weak to bother with. The water temp is sitting at 57.2°, which is pretty much bang on average for this time of year, nothing wild there.
After that, we get another week of mostly flat or tiny, weak swell until the end of the window. The morning of Monday the 24th sees a 3.0ft swell from the WSW with gentle offshore winds, but the combined energy is a weak 55 and period is short at 6 seconds. It’ll be clean, but there’s just no grunt behind it. There are no standouts here, folks. It’s a lean stretch.
Sorry, but there’s nothing worth paddling out for.
