Alright, this is Rusty. Let’s talk about what’s cooking at Sixtynine.
Honestly, it’s a slow start. The first week or so is mostly flat, with hardly any surf to speak of. There’s a long gap of several days where you’re just looking at tiny ripples or no waves at all. Don’t bother paddling out until midweek of the second week – that’s when things finally turn on.
The best of the whole outlook lands on Tuesday the 14th through Thursday the 16th of July. That’s the window to circle.
Tuesday the 14th afternoon is the real standout. Swell builds to 3ft out of the W with a solid 16-second period (groundswell), and combined wave energy hits a moderate 422. The wind goes glassy – flat calm – and with that long period, the waves will have real push and shape. This is a point-break setup kind of swell, so expect clean, lined-up sets. Crowds are possible here, so get in early.
Wednesday the 15th keeps the party going. Morning is glassy again, swell 3ft from the WNW at 16 seconds, energy up to 474. By afternoon it’s 3ft from the W at 16 seconds, energy hitting 516 – that’s the peak of the swell. Glassy conditions both sessions. This is the best you’ll see.
Thursday the 16th afternoon is still solid with 3ft from the WNW, 15 seconds, and glassy wind, though energy drops a touch to 385.
The water temp is about 81° – a touch warmer than normal for this time of year, so you’ll be fine in a shorty or even just boardshorts.
For beginners, anything over 5ft can be intimidating, but here the biggest is 3ft, so it’s manageable for most. Experts will enjoy the long-period groundswell on the cleaner days.
If you’re itching for anything earlier, Sunday the 12th afternoon has a brief moment of glassy conditions with 1ft from the SW at 16 seconds, but the energy is low and the surf is just ordinary. Not worth rushing for.
After the 16th, it fades away fast, dropping back to tiny waves and poor conditions through to the end of the outlook.
So, bottom line: the real action is from Tuesday the 14th afternoon through Thursday the 16th. Don’t waste your time before that.
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.
