The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s cooking at Peak Rock over the next couple of weeks.

We’ve got a solid run of SW groundswell on the horizon, but it’s not all smooth sailing. The wind is gonna be our biggest battle, especially early on. The water’s sitting at 57°, which is pretty much bang on average for this time of year, so no surprises there.

The first few days are a bit of a write-off, honestly. Saturday the 5th and Sunday the 6th are pumping with size – 8ft to 8ft of SW swell – but the wind is just howling. That 25 mph offshore on Saturday morning will have the wave faces clean, but paddling back out will be a proper mission. The afternoon gets messy with a cross-off. Sunday is cross-shore and choppy. It’s not worth getting too excited about.

Monday the 7th drops right off, with the swell fading to 3ft. The energy is weak, and the wind is cross-shore. A total skip day.

Now, here’s where it gets interesting. Tuesday the 8th, the swell drops a bit to 4ft, but the wind goes light and clean – a 9 mph cross-off from the west. The energy is moderate, but with a period of 18 seconds, this is proper long-period groundswell. That’s going to wrap in and offer some beautiful, lined-up waves. It’s a classic reef-break day for the experienced crew. The morning is the call.

Wednesday the 9th is a total beast. We’re talking 13ft of SW swell with a 19-second period and a massive energy reading. That’s a serious amount of water moving. But the wind is a fresh cross-onshore, making it lumpy and dangerous. That’s for experts only, if anyone, and honestly, it’s more of a big-wave tow-in or possibly a kite day than a standard paddle session.

The swell stays big through Thursday the 10th and Friday the 11th, but the wind is still a problem – cross-shore and cross-onshore, keeping things choppy.

Then, we get a window. Saturday the 12th. The morning is glassy. Dead calm, 3 mph from the NNW. Swell is a clean 8ft from the SW with a 15-second period. The energy is solid. This is the standout. Peak Rock, glassy, with a solid groundswell. It’s not for beginners at 8ft, but for the rest of us, it’s going to be epic. The afternoon turns onshore, so get out early.

Sunday the 13th is another good one. The morning is clean with a light cross-off from the NNE, and the swell holds at 7ft. Perfect for a long, fun session.

The week after that, from the 14th, the swell drops off and the wind gets messy again. There’s a spike of 10ft windswell on the 15th, but with a short 9-second period, it’s just a lumpy mess. Not for us.

The real long-range promise is on Friday the 18th of September. The swell is back up to 10ft from the SW, with a long 16-second period. The wind is a light cross-off from the NNE. The energy is strong. That’s a powerful, clean, expert-level day. It’s a ways out, so keep an eye on the charts, but it has the potential to be the best of the whole window.

Bottom line: The first weekend is a write-off. Tuesday the 8th is a nice, clean, longer-period day for the experienced surfer. Saturday the 12th morning is your top pick – glassy Peak Rock with a solid 8ft groundswell. And keep an eye on Friday the 18th of September for a potential power session.

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.
