The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at Black Rocks Jetty.
We’ve got a nice run of surf starting this Saturday, 22 August, and rolling through the end of the month. Water temp is around 77°, a touch warmer than usual for this time of year—nothing wild, but it’s a nice bonus. Overall, the pattern shows a solid pulse of SSW groundswell with clean, glassy conditions, making for some excellent sessions, especially if you’ve got some experience.
Saturday afternoon (22 August) kicks things off with 5ft from the SW, 13-second period, glassy, and wave energy at 1050—strong. This is excellent for experienced surfers. Sunday (23 August) gets even better: morning brings 8ft from the SSW at 14 seconds, glassy, energy at 2313. Afternoon holds at 7ft, still glassy. Monday (24 August) keeps the quality high: 7ft morning, 8ft afternoon, both glassy and from the SSW, energy at 2368 and 1889. These are the standout days—long-period groundswell, clean, and plenty of power.
Tuesday (25 August) drops to 5ft, still glassy and clean. Wednesday morning (26 August) holds at 5ft, but afternoon sees a drop to 3ft with a super long 18-second period, cross-off wind keeping it clean. That’s a groundswell with great shape for this reef. Thursday (27 August) turns ugly: 8ft morning with onshore wind, then 10ft afternoon with strong cross-onshore wind at 15 mph—poor, choppy. Friday (28 August) is even bigger: 13ft morning with fresh cross-onshore wind, lumpy. Afternoon is 12ft with cross-shore wind. These days are more for kite surfing than paddle surfing.
Saturday (29 August) bounces back: morning glass with 12ft from the SSW at 15 seconds, energy at 5097—exceptional for experts. Sunday (30 August) stays clean with 8ft and 7ft, glassy. Monday (31 August) fades to 5ft in the morning, still glassy, but afternoon gets a light cross-onshore breeze and 4ft.
From Tuesday 1 September, the surf drops off hard. Tuesday morning is 3ft, afternoon 3ft. By Wednesday 2 September it’s 1ft. There’s a long gap of small, marginal waves through to Sunday 6 September, with only occasional knee-high sets. Thursday 3 September offers a brief uptick to 4ft with offshore wind, but it’s small. Friday 4 September bumps to 5ft but with onshore wind.
The best days are Sunday 23 August through Monday 24 August—clean, glassy, 7–8ft SSW groundswell with long periods and strong energy. Black Rocks Jetty is a consistent reef break that loves SW swell. Crowds are possible, so expect a few locals out. That’s your window.
Rusty out.
