The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, it’s a tough one. We’re lookin’ at a long, dry spell with absolutely no surf to speak of for the first couple of weeks. From Friday the 24th of July all the way through to the end of the month, we’ve got flat, poor conditions. The wind is mostly cross or cross-off from the NNE, but with no swell to work with, it doesn’t mean a thing. The water temp is sittin’ around 80°F which is pretty much bang on average for this time of year, so no surprises there.
We finally see a tiny bit of life creepin’ in around the 29th of July, but it’s a pathetic 1ft – that’s barely a ripple – and it’s straight onshore from the west with a short, snappy 4-second period. That’s not gonna be worth paddlin’ out for. The energy is a measly 3 (combined energy of all swells directed here), so really, it’s just a tease.
We go through another flat spell at the start of August, with just a few glassy moments but no wave height to back it up. The water’s still warm and calm, but there’s just nothin’ to ride.
The first real chance of somethin’ worthwhile shows up on Saturday the 8th of August. We’ve got a 1ft swell from the WNW with a 14-second period, and the wind is a clean cross-off from the NE – that’s the best look we’ve had. The energy is up to 115 (combined energy of all swells directed here), so it’s got a bit of push behind it. Sixtynine is a fairly exposed spot, and with the swell direction matchin’ the optimum WNW, it could actually shape up okay. The swell is small, so it’s fine for all levels, and the wind’s gonna keep it glassy and clean. The only bummer is crowds are possible here, so if you’re keen, get in early.
The 8th of August is the clear standout. After two weeks of flatness, that Saturday afternoon is the one to circle. The 1ft WNW swell with that long, clean period and offshore wind makes it the best on offer in a pretty bleak forecast window.
Rusty.

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