The Lowdown
Right then, let’s have a look at what’s on the table for Triggs Beach Adelaide over the next couple of weeks. To be straight up with you, it’s a pretty quiet spell. For a sheltered little reef setup like this, we need things to line up, and they’re just not doing that for most of the run. The water’s sitting around 59°, which is pretty normal for this time of year, so nothing unusual there.
We kick off with a long gap. From Friday the 11th right through to Saturday the 19th of September, there’s really nothing worth paddling out for. The combined swell energy barely gets into double digits – we’re seeing numbers like 0 and 10 for most of it – and wave heights are either flat, or faffing about with weak little 0.3 ft to 2 ft bits of windswell. Winds are a mix of cross-off and cross-on, but even when it’s clean, there’s simply no push. It’s a frustrating stretch, just flat and quiet.
Now, we finally see something on Sunday the 20th. The morning brings a slight lift with a 4 ft swell from the west. It’s short-period windswell, only 6 seconds, so it’ll be a bit jumbly and soft. The combined energy hits 104, which is at least moderate, but the wind flips to a light cross-shore. For a sheltered north-west facing reef like Triggs, a west swell with a light breeze might just offer a few crumbly, workable waves for a beginner. It’s not going to be pumping, but it’s the best we’ve got in this whole run.
After that little blip, it drops away again. Monday the 21st has a tiny 0.3 ft south-west groundswell with a 14-second period – long gaps between sets, but no real size to it. Then Tuesday the 22nd shows a 3 ft south-west swell, but it’s short period again at 5 seconds, with a clean cross-off wind. The energy is moderate at 46, so it’ll have a bit more grunt than recent days, but it’s still a mushy, weak windswell. From Wednesday the 23rd onwards it’s back to tiny, inconsistent leftovers, barely registering.
Honestly, there’s no standout session here. If you’re desperate for a splash, Sunday the 20th morning is your best bet, but keep the expectations low. The rest is just a long, drawn-out flat spell. It’s one of those periods where the forecast could easily change, so keep an eye on it, but for now, don’t hold your breath.
