The Lowdown

G’day, Rusty here. We’ve got a solid run of surf coming up at Black Rocks Jetty, a reef break that’s very consistent. The water temp is sitting at 76°, which is about normal for this time of year. The pattern starts quietly, but builds into some serious groundswell later on.

Wednesday morning, July 15th, kicks off with clean 4ft SW groundswell, period 12 seconds, and the wind is glassy from the ENE. The combined energy is moderate at 700, and it’s looking very good – a nice, easy start. That glassy wind means the waves will be clean and inviting. The afternoon stays clean with offshore NE wind, but the swell drops to 4ft.

Thursday morning, the 16th, is a letdown – swell drops to 2ft and the wind is cross-off, so it’s small and marginal. That afternoon, it’s even smaller at 1ft. Not worth paddling out.

Friday the 17th has a new pulse of S groundswell, 4ft in the afternoon with a long 16-second period, but the wind is onshore from the SW. Combined energy is moderate (614), but the onshore wind will mess it up. The morning is even worse with cross-on wind.

Saturday the 18th is similar – a bit of swell around 3ft, but the wind is cross-on or onshore, making it poor. The best bet is to wait it out.

Sunday morning, the 19th, bounces back. Glassy WSW wind, 3ft SW groundswell with a 16-second period – clean, but the swell is small. The combined energy is moderate (492). The afternoon turns onshore again, so make the most of the morning.

Now, here’s where it gets good. Monday morning, the 20th, is a standout. Glassy SSW wind, 4ft SSW groundswell at 15 seconds, and the combined energy jumps to strong (1163). The report says excellent conditions for experienced surfers – this is a morning for the crew who know what they’re doing. The afternoon gets bigger at 7ft, but the wind goes onshore, making it more of a challenge.

Tuesday the 21st is a bit messy with cross-on wind, but the swell holds around 4ft to 6ft. The energy is moderate to strong (558 to 874). Not the cleanest, but there’s size.

Wednesday the 22nd brings a glassy morning again, 3ft SSW swell, but it’s short period at 10 seconds. The afternoon has a better 13-second period but cross-on wind. A small window for a clean session.

Thursday the 23rd has a glassy morning with 6ft SSW groundswell at 12 seconds – combined energy is strong (795). That’s a very good morning, with clean, punchy waves. The afternoon gets cross-on.

Now, Friday the 24th is a true highlight. Glassy WNW wind, 8ft SW groundswell with a 16-second period, and combined energy is very strong (2711). This is excellent for experienced surfers – big, long-period groundswell with glassy conditions. The reef will handle that period well, so expect some proper waves. The afternoon holds 8ft but the wind turns cross-on.

Saturday the 25th morning has cross-off wind from the NNW, 6ft SW groundswell at 14 seconds – still excellent for experienced surfers, with strong energy (1391). The afternoon brings rain showers and cross-on wind, so the morning is the call.

Sunday the 26th is a massive standout. Glassy NNE wind in the morning, 10ft SW groundswell at 16 seconds – combined energy is extremely strong (4026). This is for experts only. The afternoon is glassy calm with zero wind, 10ft at 16 seconds, and energy at 4202. This is the best of the run – huge, clean groundswell on a reef. Only paddle out if you’re confident.

Monday the 27th morning is cross-on, but the afternoon turns glassy calm with 8ft SW groundswell at 18 seconds – combined energy is exceptional (5146). The report says exceptional for expert surfers, and I agree. That’s a proper session for the big-wave crew.

Tuesday the 28th has glassy mornings and afternoons, 8ft to 7ft SW groundswell – excellent conditions, with very strong energy (3353 to 2866). Still for experienced surfers.

Wednesday the 29th and Thursday the 30th both have glassy mornings with 5ft to 6ft S/SSW groundswell, period 14 to 15 seconds, and combined energy still strong (1601 to 2664). Excellent conditions for experienced surfers through the mornings.

The absolute best of the lot is Sunday the 26th and Monday the 27th afternoons – huge, glassy, long-period SW groundswell. That’s the one to circle on the calendar. Crowds are listed as “sometimes” at Black Rocks Jetty, so you might have some company, but with size like that, most will be watching from the rocks.

Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Black Rocks Jetty may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
