The Lowdown

G'day, Rusty here. Look, I've had a good squiz at the charts for the next couple of weeks, and I've got to be straight with you—it's a pretty grim period for the Flies (beach/jetty). We're looking at a long stretch of tiny, weak, and often messy surf. The water's sitting at a toasty 76°, which is a touch warmer than normal for this time of year, so at least a dip won't be a shock.

The first real glimmer of hope doesn't pop up until late in the game. We've got a whole lot of nothing from now until basically the 21st of August. There's a big gap of more than a week where the surf is just too small and poorly organised to bother with. The energy is in the single digits or low double digits for most of it, with heights hovering around 1.0ft to 1ft.

Finally, on Friday the 21st of August, things start to look a bit more interesting. The morning sees a fresh offshore breeze from the NNW, cleaning up a 6ft SSW swell with a short 7-second period. The combined energy jumps to 293 (moderate), which is the most significant we've seen. The afternoon drops a touch to 5ft from the S with a gentler breeze, giving clean waves. This is the standout window, but it's still just a marginal forecast with iffy tide potential.

After that, it fades again. The 22nd drops back to 2ft, and by the 23rd we're looking at a 2ft SE swell with a bit of cross-off wind, which is okay but nothing special. The final days of the forecast have basically no swell energy at all, with some onshore junk.

So, to be honest, the only window worth thinking about is Friday the 21st of August. It's the biggest swell of the run, and the wind is good. The swell direction from the SSW is not ideal for the optimum SW direction, but it'll still produce some waves. Keep your expectations in check, but it's the best we've got.

Rusty.

Information about the Flies Surf forecast

The above surf forecast table for Flies provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Flies can be found by selecting the local surf guide option on the grey menu. Our Flies 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 (Flies) 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 Flies 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.
