The Lowdown

Right, let’s have a look at what’s on the table for the next couple of weeks, my friends…

First up, we’re looking at Trestles (Lowers). It’s a beach and reef set-up, exposed to the south-west swell, and it’s a spot that’s consistently working. The water temp? About average for the time of year, nothing unusual there.

Now, I’d be lying if I said this was a blockbuster period. The first few days are… well, they’re a struggle. Thursday 13th and Friday 14th we’ve got some small south-west swell rolling in, around 2ft to 3ft with a period of 16 to 18 seconds. That long period gives it some shape, but the wind is on it or cross-onshore. It’s not clean. The wave energy is moderate, but it’s just not happening. Those sessions are written off. Saturday 15th sees a tiny bump – up to 4ft – but with cross-onshore wind again, it’s messy and the quality is low. The whole weekend and into Monday 17th is a write-off, honestly. Very small and blown out. Combined energy drops into the three-digit numbers (around 366 to 717), which is just weak wave energy.

We’re going to hit a real slow stretch here. From Monday 17th onwards through until around Friday 21st, it’s all poor conditions and ankle-snappers. Swell height barely breaks 3ft and it’s mostly light onshore wind in the morning. The combined energy falls back into the low 200s to 300s. Not a single standout recommended.

After that, we get a slight flicker of hope around Sunday 23rd. There’s a bit of a long-period south-west swell coming through – 2ft with a period of 19 seconds. That’s a proper groundswell, and it’s long period, so it’ll be clean and peel nicely along this point. But it’s still tiny, and the wind is cross-onshore in the morning. The wave energy is moderate at 424, but the quality is still poor. Not a good call.

Monday 24th into Tuesday 25th sees a tiny, but not terrible, pulse: 2ft to 2ft south-west swell, 16 to 18 second period, and *finally* the wind goes onshore light. Those conditions are marginal but at least it’s clean. The swell energy is still low at around 306 to 430. For a dedicated surfer it’s rideable, but it’s not worth getting excited about. After that, we’re back to flat and poor conditions through to the end of the period.

Honestly, there’s not one true standout across this whole 16-day window. It’s a long, lean period with mostly small, poor-quality surf that’s either blown out or just too weak. If you’re desperate, you could paddle out on Tuesday 25th morning for a few long-period knee-high waves with clean conditions, but that’s the best of a bad bunch. Forecasts can change, and it’s not often this area stays so quiet for this long, but for now, the board stays in the car more than it hits the water.

Later days, Rusty.
