The Lowdown
Alright, mates, Rusty here. Let's cut through the noise and get straight to it. We've got a solid run of swell on the cards for Peak Rock, but it's a mixed bag of quality. The first few days are a bit of a tease, then things start to get real.
The window kicks off on Monday, August 31st. Monday morning at Peak Rock (Peak-Rock) sees a clean 6.9ft SW groundswell pushing in with a 14-second period. The light cross-off wind keeps it tidy, and with the combined swell energy at 1828, there's some proper push to it. It's a touch on the bigger side for the intermediates, but it's clean. The afternoon glass-off is the real deal though – the wind drops to a glassy 3 mph and the swell holds a solid 6.6ft. That's the kind of session you remember.
Now, pay attention, because Tuesday and Wednesday (Sept 1 & 2) get blown out. We get hit with a strong northerly offshore on Tuesday, 25 mph in the morning. It's clean and offshore, but that wind is howling and it's going to be a battle just to get out back. It's a classic "looks better than it is" situation. The swell is still decent – 5.9ft with a 16-second period – but that wind makes it a paddle workout, not a pleasure cruise. Wednesday is similar, with a moderate cross-off breeze, but the call is still "marginal." The waves are there, but the conditions are just okay.
Then comes Thursday, September 3rd. The swell jumps up, but so does the wind and the chop. Thursday morning is 9.8ft of SW swell with rain showers and a fresh cross-off, but the afternoon gets messy – 11.5ft SW and a fresh cross-shore wind that's going to make it lumpy. The energy is huge – 7454 – but this is when you need to be an expert and understand the chaos. Friday, September 4th, is better. The wind goes offshore again, and you've got a powerful 9.8ft SW groundswell with a long 16-second period. It's big and it's demanding, but it's clean. This is the first real standout, but only for the experienced crew.
Saturday, September 5th, is a washout. Near gale-force winds – 34 mph – and the swell is pumping to 13-16ft. The numbers are scary, but the wind is howling onshore-ish. This is not a surf day; this is a "watch from the cliff" day. If anything, the setup looks more interesting for kite surfing than paddle surfing. Forget it.
Sunday, September 6th, sees the swell back down to 8.2ft in the morning, and it's still clean, but the real gem is Sunday afternoon. The wind drops to a slight air, and the swell settles at a clean 7.2ft (SW). The energy is moderate at 1524, but it's glassy and the reef will be handling it nicely. This is a quality pick for a more relaxed session.
Monday, September 7th, is back down to the smaller end, 5.9ft, and the wind is fresh offshore. It's clean, but just not as much juice. Then Tuesday, September 8th, starts to fire up again. Morning is a clean 9.8ft WSW swell with a moderate offshore, and it's building. The afternoon jumps to 13.1ft with a 11-second period, and it's clean with only a gentle breeze. The energy is strong (3809) and the reef will be holding its shape. This is another one for the experienced.
Now, here's where it gets interesting. Wednesday, September 9th, is the day to circle on the calendar. We've got a big, powerful 11.5ft SW groundswell with a very long 19-second period. That's serious energy – 9510 on the combined scale – and the wind is just a gentle cross-off in the morning. This is the stand-out of the whole run. That long period will love the reef, and it'll have real size and push. It's a proper groundswell event. The afternoon turns onshore (S) which will mess it up, so make the morning session on Wednesday count.
Thursday, September 10th, holds some size – 9.8ft SW with a 17-second period – and the morning is glassy with a gentle offshore. That's a solid day, but it's the calm before the storm. Friday, September 11th, is another big one: 9.8ft SW with a 19-second period

Information about the Peak Rock Surf forecast
The above surf forecast table for Peak Rock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Peak Rock can be found by selecting the local surf guide option on the grey menu. Our Peak Rock 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 (Peak Rock) 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 Peak Rock 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
