The Lowdown
Alright folks, Rusty here. Let's check out the stretch ahead.
Right off the bat, it's flat and quiet. The first few days are a bust with tiny, weak swell. Things don't start to feel like you could get a wave until Tuesday the 25th, and even then it's small but clean.
The real standout is the morning of Sunday, August 30th. There's a clean 3ft swell from the SW, with a nice long period of 17 seconds, and the wind is glassy. The water is sittin' around 60°, which is about normal for the season. The energy is moderate, and the whole setup is glassy – that's a morning you wake up early for. It's a beginner-friendly wave, so grab the longboard.
The other one to mark on the calendar is the morning of Saturday, September 6th. That's a different story. The swell jumps to 8ft from the W, with a period of 12 seconds. The energy is strong, and it's glassy in the morning. This is for experts only. It's a powerful, serious wave that will test you, but for the experienced crew, it's got the makings of the best session of the whole outlook.
For the rest of the time, the afternoons get chopped up by onshore wind. The mornings are the window, but the waves are small and inconsistent. There's a solid week of small, clean conditions from the 25th to the 30th, so plenty of time to get wet, just don't expect anything overhead.
So, to wrap it up: the 30th of August is the pick for the everyday surfer, and the 6th of September is the one for the big-wave heroes. The rest is small and clean but not much to write home about.
Rusty.

Information about the Cox Bay Surf forecast
The above surf forecast table for Cox Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cox Bay can be found by selecting the local surf guide option on the grey menu. Our Cox Bay 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 (Cox Bay) 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 Cox Bay 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.
