Black Rocks Jetty Surf Forecast and Surf Report

G’day, I’m Rusty. Let’s have a look at what’s on offer around Black Rocks Jetty.

We’re looking at a cracking run of surf coming up, with a nice little gap at the start before it really kicks off. The first session is Tuesday afternoon, August 4th, and from there it’s pretty much game on with clean conditions and a long, sweet run of swell. The standout days are definitely Saturday the 8th and Sunday the 9th – that’s where the stars align for some top-notch waves.

So, Tuesday afternoon, August 4th, we get things started with a clean 2.6ft S swell, period a solid 13 seconds, and the wind is glassy out of the west at 3 mph. The water temp is sitting at 76.8°, which is a touch warmer than normal for this time of year – feels like a little extra warmth in the water. Combined energy is moderate (304). It’s a nice little intro.

Wednesday the 5th tries to keep it going, but the wind turns cross-on in the morning and then onshore in the afternoon, so it’s a bit messy. Thursday the 6th morning is also questionable with onshore wind, but Thursday afternoon cleans right up: glassy conditions again, 2.9ft SSW swell, 13-second period, and moderate energy (315).

Friday the 7th is a mixed bag. The morning has glassy wind but the swell is a bit weak at 2.6ft (191 energy). The afternoon is very interesting: glassy, calm wind, and a 1.3ft SSW swell with a massive 22-second period. That’s a very long period groundswell – it’ll be a bit fat and straight at the beach, but on a reef like Black Rocks Jetty, it could produce some real lines. Combined energy is moderate (335).

Now, Saturday the 8th is the first real standout. Morning: 3.6ft SW swell, 18-second period, glassy, calm wind – clean as a whistle. Combined energy is strong (779). The afternoon pushes to 3.9ft, 16 seconds, still glassy, and energy jumps to 916. This is proper surf. The swell direction is SW, which is the optimum direction for this spot. This is the best on offer early on.

Sunday the 9th keeps the party going. Morning: 3.9ft SW, 15 seconds, glassy, energy 656. Afternoon: 3.6ft SW, 14 seconds, glassy, energy 476. Beautiful, consistent conditions.

Monday the 10th morning is still glassy with 3.9ft SW, 14 seconds, and energy 593 – very good. The afternoon gets a bit onshore, so it drops off.

Tuesday the 11th and Wednesday the 12th are both glassy mornings and afternoons with 3.9ft to 4.3ft SW swell, 14 to 15-second periods, and energy in the 500s to 700s. This is a long run of clean, surfable waves.

Thursday the 13th, the swell pumps up to 7.9ft SW, 13-second period, with glassy wind both morning and afternoon. Combined energy is through the roof at 1982 and 2017. This is excellent surf, but at 7.9ft, it’s only for experienced surfers. The reef will handle it well, but beginners need to sit this one out.

Friday the 14th morning stays big at 7.2ft SSW, 12 seconds, glassy, energy 1687 – excellent for experienced crew. The afternoon gets messy with cross-shore wind at 6 mph and a weird 21-second period, so it’s marginal.

Saturday the 15th is the absolute standout of the whole run. Morning: 7.5ft SW, 18-second period, glassy wind, combined energy a massive 3468. Afternoon: 6.9ft SW, 18 seconds, glassy, energy 3426. This is the big one. The swell size is pushing into expert territory, but the direction is perfect, the wind is glass, and the period is long. This is the best week of surf we’ve seen in a while.

Sunday the 16th holds size at 8.2ft SSW, 17 seconds, but the wind turns cross and cross-on, so it’s a bit messy. Energy is still huge (4248), but the wind ruins the glass.

Monday the 17th drops back to 4.6ft SW, 15 seconds, glassy, energy 1186 – excellent again, but smaller. Afternoon is 3.9ft, 14 seconds, glassy, energy 988 – very good.

Tuesday the 18th morning turns onshore and the swell drops to 3.3ft, so it’s marginal. Tuesday afternoon glassy again with 2.3ft SW, 13 seconds, energy 321 – good for a small wave.

Wednesday the 19th finishes the run with glassy conditions, 2.3ft S swell, 11 seconds, and energy 201 – a nice little clean wave to end on.

If you’re picking one or two days, Saturday the 8th and Sunday the 9th are the sweet spot for size and cleanliness, but the real belter is Saturday the 15th –
