The Lowdown
Alright folks, Rusty here, and I gotta be real with you. Looking at Sixtynine, it’s a grim picture for the next couple of weeks. The water’s a warm 27°, pretty normal for the season, but that’s about the only good news.
We start with a big nothing. From Tuesday the 21st all the way through Sunday the 27th of July, it’s flat. Zero. Nada. There’s a tiny 0.7ft WNW bump on Tuesday morning, but it’s not worth the paddle. The wave comments just say “poor surf conditions” over and over.
Finally, on Monday the 27th, we get a 1ft SW swell with a 9-second period, but the wind’s messy. Still a no-go. More flat spells follow with small, weak swells and cross-onshore winds.
The only tiny glimmer is Saturday, the 1st of August. The combined swell energy hits 137, so there’s something moving. A 2ft W swell with a 12-second period shows up, and the wind goes glassy in the afternoon. But the call is “surfable waves but very ordinary conditions”. It’s a weak groundswell for a beach break; it’ll be straight and unexciting.
After that, it’s back to tiny 1ft to 1ft WNW swells with glassy mornings, but the energy is gone. By August 5th, we’re back to tiny 1ft SW groundswell with glassy conditions but no power.
Honestly, this is a flat spell. For a spot like this, it’s a blank run. I wouldn’t bother. Forecasts can turn, but right now, there’s nothing to ride at Sixtynine.
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.
