The Lowdown

Alright folks, Rusty here with a look at the coming swell window for Peak Rock.

We’ve got a wild run ahead, with some serious size and energy on the way, but the winds are going to be the gatekeeper. The water temp is sitting at a balmy 57°, which is a touch warmer than normal for this time of year, so that’s a nice little bonus.

Right now, it’s a no-go. Tuesday and Wednesday (15th-16th) are a write-off. We’re looking at a solid 10ft to 12ft SW groundswell with a period of 13-15 seconds, and the combined energy is massive (2462 to 6178), but a strong cross-shore wind is just ruining it. It’s messy cross-chop. Leave the board in the car.

Thursday (17th) is still a bit average. The swell drops to 7ft (1513 energy) but the cross-shore wind is still creating a lumpy surface. You could find a sneaky one, but it’s marginal at best.

Now, Friday the 18th is where we get a window. The swell settles to a manageable 6ft from the SW, but the big change is a NW offshore wind. It’s clean. The combined energy is still strong (1929). This is excellent for experienced surfers. The offshore will groom that SW groundswell nicely, and with the reef setup, it should hold shape. The wind is moderate, so it will be clean but still a bit of work. This is the standout of the first week.

Saturday (19th) is similar, with a fresh NW offshore keeping it clean, but the energy is dropping off (1162). Still a fun 6ft swell. Sunday the 20th is a drop-off; the swell gets small and the wind goes sideways again.

We hit a quiet spell with small, clean but weak surf from Monday the 23rd through the 25th. The morning of the 23rd has a N offshore wind and 5ft swell (962 energy), and by the afternoon of the 23rd it goes glassy with only 4ft swell. That glassy condition is a treat, a real rarity. It’s not pumping, but if you want a longboard and no wind, that’s your window.

Then, the ocean re-fires. Tuesday the 22nd already showed a spike to 10ft with a 16-second period (5335 energy), but it was onshore and choppy. That big pulse really hits hard again on Saturday the 26th. We get 8ft from the SW with a 19-second period and a massive 5102 energy reading. But, it’s a fresh cross-onshore wind. That long period (over 15 seconds) means it’s a proper groundswell, which is good for a reef like Peak Rock, but the wind is going to chop it up badly. This is strictly for experts if anyone is brave enough, but honestly, the quality looks poor.

The rest of the window into the end of September is the same story: plenty of size (7ft to 8ft), solid energy, but the wind angles are all wrong. It’s a frustrating run of onshore and cross-onshore breezes, keeping the surface chopped and lumpy. Not one to get excited about, unless you’re into that sort of messy, powerful session.

The best bet is Friday the 18th. Get out there for the morning session before the crowds get wise.

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.
