The Lowdown

G’day, Rusty here, lookin’ at the charts for Peak Rock. It’s a reef break, fairly consistent, and it’s got a bit of a run ahead. The water’s sittin’ at about 56°, which is pretty normal for this time of year, so nothin’ wild there.

We start off with a bit of a pulse midweek. Wednesday the 12th, we’ve got a solid 8ft SW groundswell with a 16-second period pushin’ through, but the wind’s a cross-off at 20 km/h. The combined energy is a hefty 4630 (strong), and while it’s clean, the notes say it’s a bit marginal on the tide. The swell’s over 8ft, so this is really for the experienced crew only. Thursday the 13th, it’s still thumpin’ at 10ft SW, period hangin’ at 16 seconds, and the energy is through the roof at 5036. The breeze is a 25 km/h cross-off in the mornin’, but the afternoon glassin’ off a bit to 15 km/h, and that’s where the score picks up for the experienced surfers. It’s big, it’s got power, but it’s only for those who know what they’re doin’.

Friday the 14th, the swell holds at 10ft, but the wind starts to get messy. The morning’s still cross-off at 20 km/h, but by the arvo, we’re seein’ a cross-shore with a cross-chop, and the energy drops a bit to 3553. Saturday the 15th, it’s on the way down, 8ft in the mornin’ with a light cross-on breeze, and the energy is 2560. Saturday arvo, the wind swings onshore and it’s a write-off. Sunday the 16th, the swell drops to 6ft, but the wind is cross or onshore, and the energy is down to 1264. It’s lookin’ pretty average.

Now, there’s a bit of a lull through the middle of the week. Monday the 17th, it’s 5ft SW with a 14-second period, energy down to 985, but the wind is messy. Tuesday the 18th, we get a tiny window. The morning is clean, 4ft SW with a 14-second period, light cross-off wind from the NNE at 10 km/h, and the energy is 1100. It’s small, but it’s clean. Wednesday the 19th, it’s even smaller at 3ft, and by Thursday the 20th, it’s a very weak 2ft, even with a 25 km/h offshore. The energy’s below 300, so it’s barely a ripple.

The real standout, the one you’ve been waitin’ for, is Saturday the 22nd. The swell picks back up to 5ft SW, period is 13 seconds, but the wind is a solid offshore from the NNW at 20 km/h in the arvo, and the energy jumps to 1607. It’s clean, it’s got a bit of push, and the notes say it’s excellent for experienced surfers. That’s the session to circle.

But the big dog, the one that’s a fair way out, is on Wednesday the 26th of August. The forecast is pumpin’ a 12ft SW swell, with a 15-second period, and the wind is a dreamin’ cross-off from the NE at 10 km/h. The energy is a massive 7606, and the notes call it exceptional for expert surfers. This is a serious, serious groundswell. It’s a long-period swell, so it’ll be fast and powerful, and the reef at Peak Rock will love it. The wind is light, so it’ll be glassy. This is the one you mark on the calendar, but it’s a long-range call, so keep an eye on it.

Thursday the 27th, the swell drops to 6ft, but the afternoon goes glassy with a 5 km/h wind, and the energy is 1180. A nice little clean-up session to end the run.

There’s a bit of a gap through the 20th and 21st where it’s tiny, but the energy picks up again on the 22nd. If you’re a beginner, the swell over 5ft and especially over 8ft is too big for you, so stick to the smaller days around the 18th or 19th if you’re keen. The big stuff on the 26th is for experts only.

Rusty.

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.
