The Lowdown
Alright, Rusty here. Let’s talk about the next couple of weeks. It’s a dry spell, no two ways about it. The charts are showing a long stretch of nothing before we finally see a little bump.
We’re looking at a solid 13-day gap with no real surf to speak of. From Thursday, August 6th, all the way through Tuesday, August 18th, it’s mostly flat or close to it. The swell is tiny, the period is short, and the wind is mostly cross or onshore, just messing up what little bump there is. There’s a brief moment on Monday, August 10th, where it’s glassy, but the swell is only 2ft and weak, with combined energy at just 40. Not worth paddling out for.
Things finally start to change around Wednesday, August 19th. That’s our only real window. The best bet is Flies. This is a beach and jetty setup, fairly consistent. The swell direction is from the S and SSW, which is a good match for the break. On Wednesday morning, we’ll see a 6ft S swell with a period of 8 seconds. It’s a bit of a step up in size, so it’s for the intermediate crew. The combined energy will be solid at 329, so there’s some push. The wind is a clean cross-offshore from the north, which will keep the surface smooth. The water temperature is about average for this time of year.
By Wednesday afternoon, the swell drops slightly to 5ft from the SSW, but the period shortens a touch to 7 seconds. The energy is still strong at 259. The wind stays light and cross-off, so it’ll still be clean. It’s not a classic, but it’s the only show in town. This is definitely a spot where crowds are possible, so you might have some company.
That’s it. The second week looks pretty quiet again after that one little pulse. August 20th and 21st see the swell drop back down and the wind turns onshore. It’s just a short-lived window.
So, if you’re itching, pencil in Wednesday, August 19th. It’s not a world-class day, 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.
