The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of surf coming up at Black Rocks Jetty, a reef break that’s very consistent and exposed to the SW. It’s an advanced spot, so you need to know what you’re doing. The water temp is about normal for this time of year, so nothing weird there.
The action kicks off Tuesday morning, August 11th, with some clean 4ft SW swell. The wind is cross-off and light, so the lines will be nice. The combined energy is 610, which is moderate. Tuesday afternoon goes glassy with the same 4ft SW – that’s a beautiful call for a late session.
Wednesday the 12th starts a bit wonky with onshore wind, but the afternoon cleans right up with glassy conditions and 4.3ft SW swell. The energy drops a touch to 526, but it’s still very good. Thursday the 13th is a bit of a mixed bag – morning is cross-on and choppy, but the afternoon glassed off with 3.6ft SW. The energy is dropping.
Now, here’s the standout. Friday morning, August 14th. 5.2ft SW swell, glassy as glass, and the combined energy is 1434 – that’s strong. This is exceptional surf for experienced surfers. The afternoon is even smaller at 3ft, but with a 21-second period groundswell, it’s got that long, waiting energy. That very long period will make it peel nicely at this reef, but it’s not for the faint-hearted.
Saturday the 15th gets bigger, with 5.6ft then 6.6ft SSW, but the wind is cross-on, putting some chop on the face. The energy is huge (2996 and 4122), but the quality is down. Sunday morning the 16th is a glassy 7.5ft SSW – that’s big, expert-only territory. The energy is 2977, and it’s clean. Sunday afternoon stays glassy at 6.9ft.
Monday the 17th drops back to 3.9ft SW with glassy winds, still solid. The energy is 1060. Things fade from Tuesday the 18th onwards, with small 1.6-2.6ft SW swell. The glassy mornings are nice for a log, but it’s ordinary.
The second week takes a turn. Around August 22nd, a big SSW swell arrives, hitting 13ft in the afternoon, but the wind is howling cross-on at 12-22 mph. That’s a no-go for paddle surfing – that setup looks more interesting for kite surfing than anything else. The energy is massive (8548), but it’s all windblown. The rest of the week is messy with cross-on winds and fading swell.
So, the standouts are Friday morning, August 14th, and Sunday morning, August 16th. Friday for the clean, strong SW swell, and Sunday for the big, glassy groundswell. Both are for experts only.

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. Our Black Rocks Jetty surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Black Rocks Jetty) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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).
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.
