The Lowdown

Alright folks, Rusty here. Let’s have a look at what's cooking for our local stretch.

We’ve got a solid run of surf lined up, starting straight away. The first week is the real highlight, with a couple of absolute standout windows that any experienced surfer will want to be on. There’s a bit of a lull around the middle of the second week, but it looks like things might kick back off towards the very end of the forecast period, though that’s a long way out.

First up, Saturday the 12th we get off to a decent start at Black Rocks Jetty. It’s not massive, with a clean 5ft swell out of the SSW, but with glassy conditions and that longer 14 second period, it’ll be well-shaped. The combined energy is moderate, so it’s a nice warm-up.

Sunday the 13th is the first absolute standout. The swell bumps up a touch to 5ft from the SSW, and the period stretches out to a very long 17 seconds. This is pure groundswell energy. Conditions are glassy calm, making for excellent surf for experienced surfers. The wave energy cranks up to strong levels. This is a reef break, and with that long period, it’ll be holding up beautifully. Crowds are possible here sometimes, but this is the day to be out.

Monday the 14th and Tuesday the 15th morning see some cross-onshore wind creep in, making things choppy and marginal. The swell hangs around, but the quality drops off. Tuesday afternoon, though, the wind swings back to offshore WSW, the glass comes back, and the swell jumps to a clean 6ft from the SSW with 17 second period. That's another session of excellent, powerful surf.

Wednesday the 16th is the second absolute standout. The swell builds to a solid 8ft from the SSW. That’s expert territory – too big for beginners for sure. The energy is very strong. With glassy offshore SW wind and a 15 second period, this is as good as it gets for serious surfers. The morning will be firing. The afternoon drops to a still excellent 8ft.

From Thursday the 17th into the weekend, the swell drops back down. Waves are smaller, around 3ft to 5ft, with some lighter offshores and glassy windows. It’s cleaner but much smaller, with weaker energy. Monday the 21st offers a nice little return with 5ft SSW swell and glassy conditions, promising well-shaped waves.

The middle of the second week, Tuesday the 22nd and Wednesday the 23rd, looks poor. We’ve got rain showers and onshore winds, creating messy, choppy conditions with surf dropping to under 3ft. A bit of a dead spot there for about two days.

Thursday the 24th and Friday the 25th are more promising, but the waves are small (2ft - 3ft). It’s clean and glassy though, so there might be a fun little ripple for the longboard or a foamboard.

Now, for the far end of the forecast. Saturday the 26th looks marginal during the day, but then Sunday the 27th shows a big pulse. We’re talking about a 8ft SW groundswell with a 16-second period, and glassy conditions. That’s very strong energy and would be another expert-only day. But this is over a week away, so consider it a promising rumor until we get closer.

Stay safe, read the conditions, and I’ll see you in the water.
