The Lowdown

G’day, Rusty here, and I’ve been staring at the charts for our local stretch. The surf’s gonna start off small but clean, then build into a proper south-west groundswell that’ll get serious, maybe even a bit too serious for the beachie. Let’s break it down.

Tuesday the 11th kicks things off with a clean 4.3 ft WSW swell, period 14 seconds, and glassy conditions in the morning with a slight offshore breeze. The water’s sitting at 56.3°, which is about average for this time of year, nothing weird. The energy’s moderate (756). That afternoon, the wind goes glassy again, so it’s a real nice, mellow day to ease into the water. Not a standout, but a solid start.

Wednesday the 12th drops off a fair bit. Swell dips to 2.6 ft with a long 17-second period, but the wind swings cross-off from the ENE, getting a bit fresh at 12 mph. The energy’s weak (412). It’s tidy enough for a grovel but not much to write home about.

Thursday the 13th sees a bit more life. Morning delivers 3.6 ft from the WNW, 10 seconds, with cross-off breeze and moderate energy (608). The afternoon is where it gets interesting – 4.9 ft from the west, period 12 seconds, and light cross-off winds. The energy jumps right up to 1126, and the wave comment says it’s excellent for experienced surfers. That’s a good sign.

Friday the 14th, morning swell is 5.9 ft from the WSW, long 16-second period, light cross-off wind, and energy is pumping at 1594. The comment says excellent for experienced surfers. This is a proper day. The afternoon stays solid with 4.6 ft and the same long period, energy still high at 1126. This is the start of the real run.

Saturday the 15th morning, the swell hits 6.2 ft from the WSW, 17-second period, light cross-off, and the energy is 2130. The comment says excellent for experienced surfers. This is a standout session – clean, long-period groundswell, and the wind is kind. But be warned, it’s a beach break, and that long period can make the waves a bit straight and walled. Best for intermediates and above. The afternoon sees the swell jump to 8.2 ft from the WSW, but the wind goes cross-shore and the energy spikes to 3360. The comment says marginal, with a cross-chop starting to mess things up. It’s getting big.

Sunday the 16th, morning swell is 9.8 ft from the SW, 16 seconds, energy 3929, and the wind is light cross-shore. The comment flags it as too big for this break. This is getting into expert-only territory, and even then, it’s a beach break, so it’ll be a washing machine. The afternoon drops to 7.5 ft, but the wind picks up to 12 mph cross-shore, making it choppy. Not worth it.

Monday the 17th gets absolutely thumped. Morning swell is 11.5 ft from the SW, 14 seconds, energy 6660, and while the wind is offshore and clean, the comment says it’s too big. The afternoon is 13.1 ft from the SSW, energy 8519. That’s a huge, powerful swell. For a beach break, this is not a paddle surf day – it’s more of a kite-surfing setup if you’re into that. I’d sit this one out.

Tuesday the 18th, we get a breather. Swell drops to 4.6 ft from the SW, 14 seconds, and the morning is glassy with a slight offshore breeze. Energy is 1374. The comment says excellent for experienced surfers. This
