The Lowdown
Alright, let’s get into what’s cooking for the next couple of weeks. We’ve got one main spot that’s gonna be the focus: Peak Rock – a reef that’s pretty consistent and likes a south-southwest swell. The water temp is about normal for this time of year, so you’re not looking at anything wild.
The first session to get excited about is Friday morning, September 11th. It’s a beauty: glassy conditions, a light 3 mph breeze from the southwest, and a solid 7 ft swell from the same direction. The period is a long 15 seconds, so that’s real groundswell energy – the combined energy is pumping at 2394. That’s moderate to strong. The break will be clean and powerful, but at 7 ft on a reef, it’s for the experienced crew. It can get a bit crowded here sometimes.
Friday afternoon the wind shifts to a light cross-onshore, and the swell pushes up to 8 ft with a combined energy of 3159. It gets a bit lumpy, so the quality drops.
Saturday morning, September 12th, is another standout. The wind is light and cross-offshore from the north-northeast, keeping things clean. The swell is 7 ft from the southwest with a 16-second period – that’s very long period groundswell, perfect for a reef. Combined energy is 2575. It’s for the experienced surfer, but the conditions are primo. Crowds are a possibility.
Sunday morning, September 13th, we get a fresh offshore wind from the north at 19 mph, and the swell drops to 5 ft. The period is still 14 seconds, so there’s shape, but the combined energy is down to 1132. It’s rideable, but nothing special.
Then we hit a lull. Monday and Tuesday see the swell drop right off and the wind gets messy. The combined energy on Monday is under 500, and by Tuesday morning it’s trying to pick up again with a 10 ft swell, but that’s accompanied by a 19 mph cross-shore wind making it a lumpy, cross-chop mess. That’s really only for the hardcore or the kite surfers. The quality is poor.
Wednesday, September 16th, the swell is still big at 10 ft in the morning, but the wind is onshore from the south, making it bumpy. Not great.
Now, Thursday morning, September 17th, we’re back in business. The wind is light and cross-offshore from the west-northwest, the swell is 6 ft from the southwest with a 14-second period, and combined energy is 1463. Conditions are clean. That’s a good solid session for the intermediate crowd.
The rest of the week into the weekend (September 18th to 20th) is a mix of fresh offshore winds and dropping swell. The combined energy sits around 900 to 1400, so it’s okay, but not a standout. The wind stays clean, so you’ll get some fun lines, but the size drops to 5 ft to 6 ft.
Monday morning, September 21st, is a real highlight for the second week. Light offshore wind from the north, a 6 ft swell from the southwest with a 14-second period, and combined energy of 1442. Glassy and clean – that’s the kind of morning you paddle out for.
The forecast gets a bit more uncertain from there, but Tuesday, September 22nd morning has a fresh offshore wind from the north at 19 mph, a 6 ft swell, and combined energy of 1742. It’s clean, but the wind is strong, so expect some texture.
By Wednesday, September 23rd, the wind turns nasty onshore from the south-southwest, and the swell is around 5 ft but messy. That’s a write-off.
The last real standout I can see is Saturday morning, September 26th. Glassy conditions with a light easterly breeze, a 6 ft swell from the southwest with a long 15-second period, and combined energy of 1551. Clean, powerful, and for the experienced surfer. That’s a great way to finish the run.
So, to sum it up: the best bets are Friday morning, September 11th, Saturday morning, September 12th, Thursday morning, September 17th, and Monday morning, September 21st. If you can only pick one, the Friday the 11th and the Saturday the 12th are the true standouts for the whole period – glassy or clean, with solid groundswell and good energy. The long-range ones like Monday the 21st and Saturday the 26th look promising, but it’s a bit further out, so keep an eye on it.

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.
