The Lowdown
Alright, Rusty here. Let's have a look at what's on the table.
Honestly, mate, the next couple of weeks are looking pretty grim for Flies. We've got a long stretch of poor surf conditions ahead, with only a couple of very brief windows where you might scratch a wave.
The water is running a bit colder than normal for this time of year, sitting at 69°, so you'll want the rubber on.
The first real chance for anything rideable isn't until Thursday the 30th of July, in the morning. There's a 5ft swell from the east (period 6 seconds) with a solid 19 mph breeze blowing cross-offshore. It's nothing to write home about – marginal at best – and the combined swell energy is a moderate 277. It'll be clean, but that's about it. That afternoon the wind picks up and the swell drops a touch.
We then hit another dead patch for a few days, with nothing worth paddling out for. Saturday the 1st of August, early, you might get a sneaky one. The wind goes glassy, offshore from the NNW at just 3 mph, and there's a small 3ft south swell pushing in (8 seconds). Combined energy is weak at 84, and honestly, it's surfable but very ordinary. For a short time, it'll be clean, so if you're desperate for a feel of the ocean, that's your moment.
After that, it's a whole lot of onshore slop and barely any size until we get to Tuesday the 4th of August morning. A 3ft south swell (7 seconds) with a light 6 mph offshore from the north will give you clean, but again, very ordinary waves. The energy is moderate at 107, so there's a bit of push, but it's nothing special.
The rest of the window is a write-off. Light winds, small swell, and mostly onshore. The last faint glimmer is on Sunday the 9th of August afternoon, when a gentle offshore from the NW and a tiny 3ft swell might give you a couple of clean but weak waves.
Look, Flies is a beach and jetty setup, and with these small, weak, short-period swells and the onshore winds, honestly, if you're into kiting, it might be more interesting than for a paddle surfer.
Best of the bunch? The glassy window on Saturday the 1st of August morning is your best bet, and maybe the clean offshore on Tuesday the 4th of August morning. Neither are standouts, they are just the least ugly.
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.
