The Lowdown
Alright, Rusty here again. Let’s break down Black Rocks Jetty in feet and miles per hour.
Water temp is pretty much normal for this time of year. This reef handles groundswell real well.
Saturday the 5th opens with a clean 5ft SW swell, 14-second period, light cross-off wind. Good start. But the big one is Wednesday the 9th: glassy, 13ft of SW groundswell, 17-second period. That’s some serious energy (8885). Experts only – that’s a heavy, powerful wave. Wednesday afternoon is still glassy at 12ft.
Monday the 7th gets choppy with cross-on wind and 8ft surf. Tuesday the 8th cleans up a bit with cross-shore wind, and the afternoon hits 10ft SSW (7726 energy), but still has a bit of chop.
From the 10th, we’re into the 4ft to 6ft range with a lot of glassy conditions. Thursday the 10th is clean with 6ft S swell. Sunday the 13th morning offers a 4ft, 18-second period SSW groundswell – a treat for experienced surfers if the tide plays nice.
The window fades from the 17th, with smaller 2ft to 3ft swells, weak energy. Still rideable but nothin’ to write home about.
Best bets: Wednesday morning, 9th September – big, clean, expert territory. And Thursday the 10th morning for a clean 6ft S swell.
Rusty out.

Information about the Black Rocks Jetty Surf forecast
The above surf forecast table for Black Rocks Jetty provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Black Rocks Jetty can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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).
