The Lowdown

Right folks, let’s have a look at what’s going on out there. I’m looking at the full 16-day window, and I gotta be straight with you—it’s a flat spell for a long time. We’re looking at more than a week of nothing but poor surf conditions starting from Thursday the 23rd of July. There’s a whole lot of cross-shore wind and flat water, not a single wave worth paddling for. The first real whisper of a pulse doesn’t show up until Thursday the 30th of July, but even then it’s still marked as poor.

On Thursday the 30th of July, the afternoon finally sees a tiny 1.0ft swell creeping in from the SW with a super long period of 18 seconds. That’s a groundswell, but the energy is weak (49). The wind is onshore from the WNW, so it’s not going to be clean. Friday the 31st of July stays similar, still small and messy.

The real story starts to turn around Wednesday the 5th of August. The afternoon at Sixtynine goes glassy, with a light NW breeze. The swell is still tiny at 1.0ft from the SW, but the period is a very long 16 seconds. The energy is still weak (65), but that glassy wind is a major positive. This is a brief moment of hope.

Then, Thursday the 6th of August is the standout. The morning at Sixtynine is glassy again, with a light NW wind. The swell picks up a touch to 1ft from the WNW, and the period is a very long 16 seconds. The combined energy is moderate (114). It’s not big, but it’s clean. The afternoon gets even better—calm, glassy conditions, with a 2ft swell from the W at 14 seconds, and moderate energy (104). This is the best on offer. The water temp is about average for the time of year.

So, if you’re itching for a paddle, Thursday the 6th of August at Sixtynine is your window. The swell is small, but with that glassy wind and long period, it’ll be clean and lined up. It’s a consistent spot, but crowds are possible, so keep an eye out. The forecast for the end of the second week is promising, but less certain.

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.
