The Lowdown
Righteo, Rusty here, and I’ve gotta be straight with you. For the next sixteen days, what we’ve got on offer at Trestles (Lowers) is, well, a whole lot of nothin’. This spot is usually a gem, but the forecast is looking flat, windy in the wrong direction, and just plain messy.
We’re starting off with a gap right from the jump. The first few days – from Sunday the 9th to about Wednesday the 11th – it’s all poor surf conditions with onshore winds. The swell is tiny, around 2ft to 3ft, and coming from the SSW, which isn't what we want. The period is short, around 13 to 15 seconds, so there’s no real energy to speak of. The combined energy is weak (352) on the Sunday afternoon. Honestly, don't even bother paddling out.
We get into the thick of the second week – Thursday the 12th through to maybe the following Wednesday – and it's more of the same grind. Swells hover around 2ft to 4ft, but the wind is cross-onshore from the W or WSW. It’s just choppy and junky. A few afternoons like Thursday the 13th and Saturday the 15th show a marginal call, but with a period of 16 seconds and combined energy starting to creep up (443 and 743 respectively), there’s a little more push in the water. But the wind is still a problem.
For a standout... look, there isn’t one. Not a single recommendation makes the cut. The best you might get is a very early morning paddle on the 14th or 15th if you’re desperate, when wind is lighter, but it's still skinny and wobbly.
The one thing I will say: the water temp is a story for the first day. On Sunday 9th, the water is running at 76°F, which is a massive 8°F warmer than usual – that’s very unusual. So if you’re going for a swim, it’ll be like bathwater, but it won’t help the surf.
Everything after the 16th of August looks just as poor. The swell drops back to 1ft to 2ft with cross-onshore winds again. No standouts, no hope in sight. It’s a long, flat run for Trestles. Forecasts change, mate, but right now, the water looks more interesting for kites than surfboards.
Rusty.
