The Lowdown

Alright, this is Rusty. Let’s look at what’s coming.

We’ve got a solid run at Black Rocks Jetty. The water is 76°, which is a touch warmer than usual for this time of year. The real story is the pulse of SSW groundswell with a very long period – 18 seconds on Tuesday morning – that’s proper energy. The combined energy is 1633 (moderate to strong), and with a glassy 3 mph easterly, the waves will be clean at 5 ft. This is excellent for experienced surfers, but the long period means it’ll be a bit straight at this beach setup; expect lulls between sets. The afternoon picks up to 6 ft with glassy WSW wind, energy hitting 3099. Tuesday is your standout – clean, punchy, and consistent for the crew who know what they’re doing.

Wednesday the 16th is serious. Morning sees 8 ft of SSW swell at 15 seconds, glassy westerly wind. Energy is 3221 – strong. This is expert-only. The afternoon stays solid at 8 ft with glassy conditions, period drops a little. If you’re not comfortable in heavy waves, give this a miss.

Thursday the 17th drops to 5 ft in the morning, but the wind is onshore with a 13-second period – a bit messy. The afternoon is better: 4 ft with glassy W wind and 12-second swell, clean and fun with moderate energy (626).

Friday the 18th is smaller: 3 ft, glassy WNW wind. Energy is low (312). Good for beginners, not a standout.

Saturday and Sunday the 19th and 20th are very similar: 3 ft to 4 ft of SW swell, 14-15 second period, glassy or clean wind each afternoon. Energy stays moderate (390-579). Consistent, clean, and user-friendly.

Monday the 21st bumps back to 5 ft in the afternoon, glassy NW wind, 15-second period. Energy hits 898. That afternoon session is a gem.

Tuesday the 22nd is tricky. Morning is 3 ft and glassy, afternoon gets a 3 mph offshore NE wind with 3 ft of long-period swell (17 seconds). Clean but small – better for a point or reef.

Wednesday the 23rd: morning is a bit messy with cross-on wind and 5 ft, but the afternoon turns glassy with calm sea and 5 ft of SW swell. Energy 1026. That afternoon window is the pick of the day.

Thursday the 24th brings a solid late-run: 6 ft in the morning with glassy NNW wind and 17-second period, energy 2035. Another strong offering for experienced surfers. Afternoon similar at 5 ft.

Friday the 25th is smaller again, 4 ft, messy morning but glassy afternoon. Energy low to moderate (522). Not a standout.

Saturday the 26th: morning is tiny at 2 ft and cross-on, but the afternoon jumps to 6 ft with glassy conditions, energy 1216. That afternoon session is the one.

Sunday the 27th is a big warning: 8 ft in the morning with onshore wind and 15-second period, energy 2825. Huge and messy. Afternoon improves to 8 ft with clean cross-off N wind, but still only for experts.

Monday the 28th and Tuesday the 29th settle into a nice rhythm: 5 ft to 6 ft, clean offshore or glassy winds, moderate energy (683 to 1052). Solid surfing for the experienced.

Wednesday the 30th tails off to 3 ft and 3 ft with clean offshore wind, period staying long at 13-17 seconds. A nice way to end the fortnight, but dropping fast.

Standout: Tuesday the 15th – 5 ft to 6 ft, very long period, glassy all day, warm water. That’s the one. Followed by Wednesday the 16th for power, but keep it expert-only.

No gaps here – this break is very consistent, so waves every day of the 16-day run.

Rusty.
