The Lowdown
G’day, Rusty here. Alright, let’s break down what’s coming for Peak Rock over the next 16 days. It’s a reef break that’s fairly consistent and likes a SSW swell, but we’ve got a real mix of conditions, so you’ve got to pick your moments.
Water temp is about 57°F, which is normal for the season, nothing crazy there.
The real standout kicks off this Saturday, September 12th. We’ve got a solid 2.2m (about 7ft) SW swell rolling in with a very long 16-second period – that’s proper groundswell, and the combined energy is a strong 2575. Wind is light offshore from the N, so it’s going to be clean. This is for experienced surfers given the size, but it’s the pick of the first week. Then Saturday afternoon goes dead glassy with 2.1m (7ft) SW swell – dreamy conditions for a few hours.
Sunday the 13th the swell drops to 1.6m (5ft) with a fresh 30 km/h (19 mph) N offshore wind – clean but a bit of a battle. Energy is moderate at 1134. Afternoon same story. Not the best.
Monday the 14th is small, 1.0m (3ft) with a moderate NW offshore. Clean but tiny, energy only 372.
From Tuesday the 15th to Thursday the 17th it gets messy. Swell builds to over 2.5m (8ft) but wind turns cross, cross-on, and onshore with gusts up to 40 km/h (25 mph). Energy numbers are high – up to 6538 – but it’s lumpy and choppy. This setup looks way more interesting for kitesurfing than paddle surfing.
Friday the 18th brings some relief. Morning has 1.5m (5ft) SW swell with a moderate NW offshore, energy 1305. Clean and okay. Not a standout.
Saturday the 19th has fresh 35 km/h (22 mph) NNW offshore winds with 1.8m (6ft) SW swell. Clean but windy. Energy 1315.
Then a quiet spell from Sunday the 20th to Tuesday the 22nd. Swell drops to 1.0m (3ft) and wind goes onshore or cross, poor quality. The 22nd has 3.0m (10ft) SW swell but blown out by onshore winds. Skip it.
Here’s the real gem. Wednesday the 23rd of September. Morning has 2.2m (7ft) SW swell with a 15-second period, energy 2566, and a light NNE cross-off breeze. Clean, powerful. That’s a proper session.
Thursday the 24th is another beauty. Morning has 2.1m (7ft) SW swell with gentle cross-off, and afternoon goes dead glassy – 2.0m (7ft) SW, zero wind, energy 2205. The standout of the entire forecast.
Friday the 25th sees a massive jump. Morning is 3.0m (10ft) SW swell with an 18-second period, energy 6177, light cross-off wind – clean but huge. Experts only. Afternoon drops to 2.5m (8ft) with moderate N offshore, still solid.
Saturday the 26th is a write-off – gale force offshore winds at 50-65 km/h (31-40 mph). Hard to paddle, even if clean.
Sunday the 27th finishes with a bang. Morning has 4.0m (13ft) WSW swell with a fresh cross-off, energy 5119 – monstrous but clean. Afternoon goes absolutely mental: 6.5m (21ft) SW swell with energy 14435. 30 km/h (19 mph) cross-off wind keeps it clean but it’s for big-wave chargers only.
Bottom line: the opening Saturday and Wednesday/Thursday of the second week are the true standouts. The 23rd and 24th are the best on offer. The final Sunday is for the brave.
Rusty signing off.

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.
