The Lowdown
G’day, it’s Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty bleak for a proper paddle on the South Coast. We’ve got a long stretch of small, weak surf and messy winds, so if you’re hanging out for a wave, you might be waiting a while. But don’t bin the board just yet – there’s a small window down the track that might just save the run.
We’re looking at Triggs Beach Adelaide, a sheltered reef break that needs a solid WSW swell to get going. The water temp is sitting about average for this time of year, so nothing wild there. For the first week, it’s a write-off. Monday the 3rd has a tiny 2ft cross-onshore chop, and it just gets smaller and more disorganised from there. The energy’s weak, with combined readings mostly in single digits or low teens, so it’s barely a ripple. Wednesday and Thursday are flat as a tack, with the odd 1ft to 1ft dribble, and cross-shore winds aren’t helping. Friday’s got a clean-looking light breeze but the swell’s gone – you’re looking at 0.3ft, so don’t even bother.
Then we hit the weekend of the 8th and 9th of August. Saturday afternoon kicks up a bit of a windswell to 5ft, but it’s accompanied by a strong 28 mph cross-shore and messy conditions. The energy jumps to 123, so there’s some push there, but it’s not for the faint-hearted and definitely not for a beginner – over 5ft is pushing it. Sunday’s just as ugly with a strong onshore breeze. Honestly, the setup looks more like a kite-surfing day than a surf day.
The middle of the following week, the 10th and 11th, sees a bit more life. Monday’s got 3ft from the WNW, but it’s cross-onshore and choppy. Tuesday the 11th has a more solid 5ft from the north, with the energy hitting 154, so there’s some proper power in the water. But the winds are still cross-shore, and the period’s a short 6 seconds, so it’s likely to be lumpy and uninviting. Still well under 8ft, so not an expert-only zone, but the quality just isn’t there.
Now, here’s the one to keep an eye on. Friday the 14th of August. The morning has a clean 6ft from the WNW with light offshore winds – that’s the best combo we’ve seen all run. The energy is up at 158, which is strong, and the conditions are finally glassy. It’s the standout of the fortnight, no question. A bit later in the afternoon, the swell drops to 5ft and goes glassy, which would still be fun, but the morning looks like the pick. It’s a reef, so that longer period would help, though it’s only 5 seconds here, so the shape might be a bit ordinary.
After that little highlight, it fades fast. The 15th and 16th drop right off, with tiny 0.3ft to 3ft leftovers and a clean but empty lineup. The 17th has a small 2ft from the west, but the winds turn messy again. By Tuesday the 18th, it’s flat.
So there you have it. Don’t rush out this week – it’s a dead loss. Keep your powder dry for Friday the 14th. That’s the one. It’s not a full-blown classic, but it’s the best we’ve got, and the clean conditions will make it worth the drive.
Rusty.
