The Lowdown
Right, folks. Rusty here. Let's have a look at what's coming our way for the next couple of weeks. Don't expect perfection early on, but there's a decent swell train lining up, especially for those who know how to handle a bit of power.
Overall, we're looking at a solid run of South West groundswell, with a classic long-period pulse hitting from Thursday the 13th. The water temperature is sitting at 64°, which is about a degree and a half cooler than average for this time of year – you'll feel that nip on a morning paddle.
The standout by a long shot is Cozies and Geeries, a reef and point set-up that loves a good West-South-West swell. The pick of the bunch kicks off on Thursday afternoon the 13th. We've got a clean 7ft of WSW groundswell with a very long 17-second period, pumping in a massive 2929 units of energy. That's proper groundswell. The wind is a cross-off from the South-South-West, which will keep the faces clean. This is the one to clear your schedule for.
Now, Friday the 14th keeps the pace. The early session is a bit tricky with a cross-shore wind, but Friday afternoon shapes up nicely. It drops slightly to 7ft, still from the WSW, period 16 seconds, and winds go cross-off again from the South-South-West. Another great window for experienced surfers.
The weekend gets a bit mixed. Saturday the 15th sees the swell drop to 5-6ft, and the wind turns cross-onshore, so it’ll be a bit bumpy. Sunday the 16th holds at 7ft but with a stronger cross-shore breeze, and some light offshore wind in the afternoon from the North-West. It's not the cleanest, but there's still swell to be had.
We hit a bit of a wall on Monday the 17th and Tuesday the 18th. A big pulse of 12ft swell hits, but it comes with strong onshore gales and rain. That’s a full-on blown-out mess. The energy readings hit over 6300, but without clean wind, it's for the kite crew, not for paddle surfing.
Things settle a touch from Wednesday the 19th, but it's still wind-affected. There's a real clean-up happening on Thursday the 20th. The morning brings a solid 12ft swell with a moderate cross-onshore, but the energy is huge at 6771. Still a bit rough around the edges.
Friday the 21st looks more promising again. Swell drops to 8-8ft, winds go light and cross-shore. That's a good, manageable size that should produce some nice lines. Saturday the 22nd is a write-off with onshore wind.
Now, for the second week, we're looking at a more unpredictable pattern. Sunday the 23rd of August has a morning slot with 7ft swell, but it's onshore. The afternoon jumps up to 8ft with a longer period and light northwest wind, so keep an eye on that one. Then Monday the 24th through Tuesday the 25th is a complete wipeout with gale-force onshores.
The real long-range gem to keep an eye on is Thursday the 27th of August. It’s a long way off, but the data suggests a massive 10ft WSW groundswell with a very long 18-second period, pumping out massive energy of 6657. The tricky bit is the moderate cross-onshore wind. If that eases, it could be an epic, powerful day. Friday the 28th sees a drop-off with the swell down to 8ft but with better cross-shore winds.
Keep the faith. The first week has a couple of blinders, and the last few days of the outlook have potential if the wind plays ball. This is Rusty, signing off.

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 Cozies and Geeries 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.
