The Lowdown
G’day, I’m Rusty, and here’s the surf outlook for your local spot.
Honestly, the next 16 days are a tough stretch. There’s no classic swell coming, and most of the time it’s flat or junk. The first real look comes on Monday, August 19th, morning, and you’ve got a long quiet spell from the 13th through the 18th before that. Mark it if you’re keen, but keep expectations low.
Flies is the only break in the game—a beach and jetty setup that’s fairly consistent, but it can get some company sometimes. Water temp is about average for the season.
Monday, August 19th, morning – This is your best window. Flies gets a south swell at 4 ft, 7 seconds, with moderate energy (131). Wind is offshore from the NNW at 6 mph, keeping the surface clean. It’s not big or punchy, just surfable waves with ordinary conditions, but that offshore breeze makes it the standout of a flat run. The south direction isn’t the ideal SW the break loves, but you’ll find some rideable lines.
Saturday, August 23rd, morning – Another small hope. A south swell of 2 ft at 6 seconds (weak energy at 43), but the wind goes glassy. That’s a rare gift here. It’s still poor surf overall, but glassy conditions could give you a few clean, gentle waves if you’re patient.
After that, it’s ugly. Strong onshore winds, lumpy chop, or tiny swell take over. The week starting August 25th is dead with 19–22 mph southerlies thrashing things. Thursday, August 28th, morning has offshore NW wind at 12 mph, but the swell is only 1 ft—barely a ripple.
If you’ve got a kite, the stronger south wind days around August 16th and 21st might be more fun than anything on a surfboard. For paddle surfing, hang tight and watch for a change.
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.
