The Lowdown
Alright, let’s talk about Sixtynine. The next week and a half is looking pretty grim, with a real small window of tiny, clean waves and then a long flat spell that stretches all the way to the end of the month. The best you’ll find is a little Thursday afternoon session on July 16th – it’s only 3ft of west swell, but with a 15-second period that’s proper long-period groundswell, so the shape should be nice even if the size is tiny. The wind goes glassy, so it’ll be clean as a whistle. Combined energy is moderate at 272, so there’s a bit of push despite the height. That’s about as good as it gets. Friday afternoon July 17th has a bit of 2ft with glassy conditions too, but it’s weaker. After that, the swell fades fast – Saturday morning drops to 2ft with cross winds, and by Sunday it’s down to 1.0ft. From Monday July 21st onward, it’s basically flat. There’s a tiny 0.3ft showing up on July 27th and again on the 29th and 30th, but that’s barely a ripple. The whole run from July 22nd through the end of the forecast period is mostly zeros. So if you’re desperate for a paddle, Thursday afternoon July 16th is your only real shot – small but clean, and consistent enough for an intermediate.

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.
