The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – we’ve got a pretty grim 16-day stretch ahead for Flies. The swell is small, the wind is mostly messy, and there’s hardly a session worth paddling out for. The first solid surf doesn’t even show up until Monday the 3rd of August, and even then it’s a write-off.
We kick off on Saturday morning the 1st of August with a tiny 2ft S’ly swell, period a weak 8 seconds, and a cross-shore breeze that’s chopping things up. Combined energy is a paltry 84 (weak). Water temp is sitting at 71°, which is about average for this time of year. It’s poor – don’t bother.
Sunday the 2nd is even smaller, 1ft to 2ft, onshore wind, and the period drops to 4 seconds at one point. Just leave your board in the car.
Then Monday the 3rd of August – we see a jump in size to 6ft in the morning, 6ft in the afternoon, from the S, period 7-8 seconds. Combined energy hits 303 and 477 (moderate to strong). But here’s the catch: it’s blowing a strong 19-25 mph cross-shore with light rain, making it a total mess. The wave comment says “poor surf conditions.” This is more of a kite-surfing setup than a paddle session.
Tuesday the 4th has a marginal morning with 5ft S swell, period 8 seconds, and a light NE cross-shore – the only hint of something barely rideable, but the combined energy is still only 234 (moderate), and the wind state is lumpy. It’s a 1/10 – not worth rushing.
From Wednesday the 5th through to Sunday the 16th, it’s a long, bleak run. Swell stays under 5ft (mostly 1ft to 4ft), winds are cross or cross-on, and combined energy drops below 200 (weak to moderate). The only tiny glimmer is on the morning of Wednesday the 12th of August: a 3ft S swell, period 7 seconds, with a light NNW offshore wind, giving clean conditions. But it’s only 94 (weak) combined energy – ordinary surf. The morning of Thursday the 13th also has a 2ft S swell with a glassy offshore NW wind at 3 mph, but again, tiny.
Honestly, over this whole 16-day window, there’s nothing that stands out. The best on offer is the Wednesday morning the 12th, with a clean offshore wind, but the waves are small and weak. If you’re desperate, that’s your window. Otherwise, keep your wax dry.
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.
