The Lowdown
Alright, folks, Rusty here. Let's chew the fat on Peak Rock's 16-day outlook.
We start off slow. Wednesday the 19th is a total bust with a 40 km/h north wind making a mess. Don't even think about it. Things turn around Thursday the 20th. That morning you've got a clean 2 ft SW groundswell with a long 18-second period, and a light offshore from the NNW. It'll be glassy and inviting. The water temp is about average for this time of year. The energy is moderate (348), but with that long period, expect longer waits between sets. It's a fairly consistent reef, so you'll get waves, but it might be a little straight. Crowds are possible on a clean morning like this.
Friday the 21st is the real standout for the first week. The afternoon is your target. We've got a 4 ft SW groundswell, 15-second period, with a light cross-off from the WNW. The energy is solid (1312), and the waves are gonna have some real shape. "Very good surf conditions" is the word, and I believe it. This is the one to try and get out for.
Saturday the 22nd gets big. The swell hits 8 ft in the morning and 8 ft in the afternoon, still from the SW with a 15-second period. That's a lot of water. The energy is massive (2906), and it's only for the experienced crew. If you're not comfortable in heavy, overhead surf, take a pass.
Sunday the 23rd is still solid for the experts: 7 ft to 7 ft of SW groundswell, clean conditions, and light winds. Another top day for those who can handle it.
Monday the 24th drops to 5 ft, but a fresh offshore from the NNW keeps it clean. More manageable for a strong intermediate. Tuesday the 25th is a no-go with onshore winds.
From Wednesday the 27th through to Monday the 1st of September, the winds turn ugly. Strong onshores and cross-onshore winds make for lumpy, choppy conditions. There's plenty of swell, but it's not for paddling. With the size and these winds, it looks more interesting for kite surfing than paddle surfing.
Now, here's the long-range keeper. Tuesday the 1st of September morning. We've got a 6 ft SW groundswell, 14-second period, and a light offshore from the NNE. The energy is strong (1489), and the forecast says "excellent" for experienced surfers. It's a promising call, but being a week and a half out, don't book the time off just yet. Crowds are possible, so plan for an early start.
The rest of the first week of September looks okay, but nothing tops that Tuesday morning.
So, your best bets: Friday the 21st afternoon for a fun, clean wave, and Tuesday the 1st of September morning for a bigger, more powerful session. Saturday the 22nd and Sunday the 23rd are for the 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.
