The Lowdown
Alright crew, Rusty here again. Let's break down what we've got in the old hammer units. It's a skinny period overall, with only Flies on the menu, a beach/jetty break with a southwest exposure.
Forget the next few days. Right now through early next week, the wind is blowing from the wrong directions and it's choppy as hell. On Monday, August 3rd, there's a pulse of energy with the combined swell energy hitting 599 and 837, and wave heights around 8ft to 8ft. But it’s coming with strong, messy cross-shore winds from the SSW and SW. That's not a surf report, that's a warning. Looked better for a kite.
Tuesday, August 4th teases us. A clean, cross-offshore north wind and a light breeze on the morning session, with a 4ft S swell. The energy is moderate at 191. It’s described as "surfable waves but very ordinary conditions." A short 8-second period keeps it from being anything special, and the afternoon turns ugly again.
Now, here's your one real shot. Friday, August 7th. Morning brings a clean WSW cross-offshore breeze at 15 km/h, a solid 5ft SSW groundswell with a combined energy of 359, and a 7-second period. They’re calling for "good surf conditions." That 5ft is a decent size for intermediates, but too big for beginners. The wind is right, the wave energy is there, and it's the clear standout. The swell direction is a little off the optimum for Flies (SSW vs SW), but the clean conditions make it the best bet. Crowds are "sometimes," so don't expect it to be empty.
After that, it's a long, slow decline. From the 8th onward into mid-August, we’re looking at smaller surf, bad wind, and weak energy. By the 12th and beyond, wave heights drop below 3ft and the energy numbers fall into the double digits. It’s pretty much flat by the 16th and 17th, with just a couple of feet of weak, short-period junk.
Water temps were a perfectly normal 71°F at the start, nothing unusual there.
So, to put it plainly: your best bet is Friday, August 7th, early morning. Get in the water before the wind swings and the crowds show. The rest of the 16 days is pretty much a write-off.
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.
