The Lowdown
Alright, Rusty here, let’s break down the Peak Rock window.
The pattern is a long run of SW groundswell, but the wind is going to be the deciding factor. The first few days are messy, but if you wait, it gets good. The standout is Monday morning, August 31st. That’s the one.
The water is sitting around 56°, just a touch warmer than average for the season.
Friday, August 28th – Afternoon is a dud. 2.1m SW swell, 17-second period, but a 12 mph cross-on wind from the SW chops it up. Energy is moderate (2507). Pass.
Saturday, August 29th – Morning is the call. 1.8m SW swell, 14-second period, with a 9 mph cross-off wind from the W. Clean, fun, moderate energy (1328). Afternoon gets cross-shore, so get it early.
Sunday, August 30th – Another morning session. 1.8m SW swell, 13-second period, cross-off wind from the WNW at 9 mph. Clean enough. Moderate energy (1217).
Monday, August 31st – This is the one. Morning has a 2.1m SW swell, 14-second period, and a light 6 mph cross-off from the WNW. That’s glassy potential. The energy is moderate (1828). The afternoon gets a light cross-on, so the early bird catches the wave.
Tuesday, September 1st – Morning is a no-go. 25 mph offshore from the N is too strong. You won’t be able to paddle out. Afternoon is better with an 18 mph offshore from the NNW and a 1.6m swell, but it’s still a battle.
Wednesday, September 2nd to Friday, September 4th – Mixed cross-shore and cross-off conditions. Swells stay in the 1.9m to 2.5m range, SW, with periods of 13-15 seconds. Energy is moderate to strong (1214 to 3178). Friday afternoon, September 4th, has a 2.5m, 15-second SW swell with a 12 mph cross-off from the WNW and strong energy (3178). Good, but Monday morning is still cleaner.
Saturday, September 5th to Sunday, September 6th – Getting bigger and windier. Saturday morning is 28 mph offshore from the NNW, 2.3m SW swell. Brutal for paddling. Sunday morning is 3.0m with 28 mph cross-off wind. This is expert-only, and the energy is strong (2757). On those windy days, the setup might be better for kite surfing than paddle surfing.
Monday, September 7th to Wednesday, September 9th – Swell drops, period shortens. Monday afternoon is a poor 2.5m, 7-second windswell with cross-shore chop. Not worth it.
Thursday, September 10th to Friday, September 11th – Thursday is a mess with 18 mph cross-shore winds. Skip it. Friday, September 11th morning, though, is a long-range promise. A 2.3m SW swell, 16-second period, cross-off wind from the WNW at 9 mph, and strong energy (3676). Could be a hidden gem if the wind behaves.
Saturday, September 12th – Finishing strong. Morning has a 1.8m SW swell, 17-second period, and offshore wind from the NNW at 12 mph. Energy is strong (2101). The afternoon is even lighter, with 6 mph offshore wind and 1.6m swell. Clean, easy.
Best on offer: Monday, August 31st, morning session.

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.
