The Lowdown

G’day, Rusty here. Alright, let’s break down this Peak Rock run over the next couple weeks. There’s plenty of swell on the cards, but you gotta pick your moments – the wind swings around a bit.

The first chance to get in the water is the afternoon of Thursday, August 20th. It’s small at 2ft of SW groundswell with a long 17-second period. The water temp is 56.1°F, right about average for this time of year. The wind is a light cross-offshore from the WNW at 9 mph, so the surface is clean. Energy is moderate (364). A nice gentle start.

Friday the 21st steps up to 4ft with a 15-second period, but the wind bumps up to 16 mph, still cross-off. The energy is moderate-strong (985-1289), but the forecast flags tricky tide windows. Not a top pick.

Saturday the 22nd brings big 10ft SW swell, but the wind is howling at 19 mph. Morning is cross-off, afternoon turns to a full cross-shore. The energy is very strong (6594) but the ocean is messy with cross-chop. This is for experts only – honestly, it’s looking more like a kiteboarding day than a paddle session.

Now, Sunday the 23rd is the real winner of the first week. The morning offers 7.5ft of SW swell with a 14-second period. The wind goes light offshore from the NNW at just 9 mph – clean, clean, clean. Energy is strong (2448). The forecast says it’s excellent for experienced surfers. The afternoon gets even better: wind dropping to 3 mph, nearly glassy, and clean 6.5ft waves. This is the one to lock in. Crowds are possible here sometimes, and with conditions this good, expect a few other folks out.

Monday the 24th is a step down – still 5ft of SW swell, but a fresh 19 mph offshore wind from the NNW makes for clean but choppy, fast faces. Energy (953-1107) is moderate. It’s surfable, but not a stand-out.

Tuesday the 25th turns ugly – 7ft of WSW swell with onshore wind and some light rain. The afternoon brings 10ft with strong onshore wind. Wednesday and Thursday are sloppy with onshore chop and moderate energy. Poor conditions.

Thursday the 27th afternoon offers a clean-up. The swell is 4ft from the SW with a 12-second period, and the wind goes light cross-off from the NW at 6 mph. Energy (983) is moderate. The forecast says very good surf – a nice little window after the slop.

Friday the 28th is a mixed bag – 6ft of SW swell with a long 17-second period has good potential, but a fresh 19 mph offshore wind from the NNW keeps things clean but powerful. Energy is strong (2114). Good for strong surfers.

Saturday the 29th and Sunday the 30th are blown out – strong onshore winds, small 2.5-3.5ft slop. Energy drops to weak-moderate (238-557). A wasted weekend.

Monday the 31st of August is a sneaky one. The swell is 4ft from the WSW with an 11-second period. The wind goes light offshore from the N at 9 mph – gentle and clean. Energy (600) is moderate. Not huge, but clean and glassy for a fun paddle.

Then Tuesday the 1st of September is a real gem. The morning is 2ft of SW groundswell with a 17-second period and light cross-off wind. The afternoon though – glassy conditions, wind from the SSE at just 3 mph, and a clean 2.5ft SW swell with a 16-second period. Energy (741) is moderate. This is a dream session for a longboard – clean, glassy, long lines.

Wednesday the 2nd of September gets punchy. Morning is a clean 6ft SW swell with a moderate offshore wind from the N. The afternoon is a big one: 10ft of WSW swell with offshore wind from the NNW at 12 mph. Energy is very strong (3347) and conditions are excellent for experienced surfers. Another standout for the brave.

Thursday the 3rd of September keeps the run going with 8ft of SW swell and a fresh 22 mph offshore wind from the N. Clean but powerful – only for the fit. Energy (3078) is very strong.

Friday the 4th of September ends the run with 10ft of WSW swell and a strong cross-shore wind at 22 mph. Energy hits very strong (6096-8901) but the ocean is lumpy cross-chop. Kite surfers will love it; paddlers will struggle.

So, to wrap it up:

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.
