The Lowdown
G’day, Rusty here. Bit of a quiet spell ahead for Sixtynine, I won’t lie. The next week or so is basically a flat, wind-affected write-off. We’ve got a long gap with no surf on offer right up until the first recommendation kicks in on Friday, August 6th, more than a week away.
The water temp is sitting at 80°, which is about average for this time of year – no surprises there.
The standout window is that first Friday morning, August 6th, through the weekend. For Sixtynine, a small long-period groundswell from the west is showing around 2–2 ft, with a period stretching to 14 seconds. Combined wave energy reads moderate at 107 (Fri morning) and builds to 153 by Saturday morning – that’s enough to get your attention on a clean, glassy day. The wind turns glassy or light cross-offshore, so conditions should be smooth. It’s not big, but for a spot that’s been dead for days, this is the best on offer. Just know that with such a long period (over 15 seconds on some pulses) and a beach setup, the waves could be a bit straight and fat – better for a longboard or a funboard.
Beyond that, the following week stays very small and ordinary. Saturday, August 8th still has that glassy west swell around 2 ft, holding the energy (150-153) but it’s not going to blow you away. No other standouts in the second week.
Right now, it’s a waiting game. Be ready for that first glassy morning in August – it won’t be epic, but it’ll be surfable and clean.
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.
