The Lowdown

Righto, let’s have a look at Peak Rock. This is a reef setup that takes a south‑southwest swell and it’s fairly consistent, so there’s surf to be had across the next couple of weeks. The water temp is about average for this time of year, nothing unusual there.

We kick off Saturday the 12th morning with a solid 7ft SW groundswell packing serious energy (2575). The wind is light offshore from the north, making for clean, lined‑up waves – proper excellent conditions but only for experienced surfers at this size. That afternoon goes glassy with the wind dropping to zero, a 7ft SW swell rolling in at 15 seconds (2026). This is the standout of the whole run: clean, glassy, powerful. If you can handle it, Saturday is the day.

Sunday the 13th sees a drop to 5ft SW, but the wind cranks up to 19 mph from the north, offshore but a bit of a battle – fresh and clean but hard work. Not the pick.

By Monday the 14th, the swell fades to 3ft and the wind stays strong offshore. The energy drops to 372 – weak. Surfable but nothing to get excited about. Tuesday and Wednesday get messy: big 8ft to 12ft SW swells but with strong cross‑shore winds and rain showers. The power is there (4766 on Tuesday arvo) but the quality is poor. This setup looks more interesting for kite surfing than paddle surfing.

Thursday the 17th and Friday the 18th improve a bit. Thursday morning sees 7ft SW with a gentle cross‑shore breeze – still a bit lumpy but workable. Friday morning is the better bet: 6ft SW with a moderate offshore from the NNW, clean and lined up (1238), good for intermediates.

Then we hit a bit of a quiet patch late in the first week, with small clean waves but barely enough oomph.

But hold onto your board – Monday the 21st is a big one. A 10ft SW groundswell with a very long 18‑second period, light offshore from the NNW, and massive energy (6507). This is for experts only. The waves will have serious push and long gaps between sets – a proper groundswell that will love the reef at Peak Rock. Over 8ft, so beginners stay out. That morning is the second real standout: clean, powerful, and intimidating.

Tuesday the 22nd keeps the goods – 8ft to 10ft SW, moderate offshore, clean and pumping. Another day for experienced crew.

The following week stays active with solid 7ft to 8ft SW swells and generally clean conditions, though winds shift around. Friday the 25th morning is worth a mention: 7ft SW, 16 seconds, light breeze and clean (2383) – again, more for the skilled lot.

Crowds? Peak Rock can get them sometimes, but with this size and the expert nature of the waves, you’ll likely have plenty of room. The reef handles long‑period SW swell beautifully, so those 16‑18 second groundswells will wrap in nicely.

Bottom line: this whole stretch is for intermediate to expert only. Saturday 12th and Monday 21st are the absolute standouts – both glassy or light offshore, both powerful groundswells. The gap around the middle of the first week (Monday arvo to Wednesday) is a write‑off for quality surfing due to strong onshore winds and chop. Otherwise, there’s plenty of clean, strong swell to go around.

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.
