The Lowdown
Alright, this is Rusty. Let's have a look at what's cookin' for Flies over the next couple of weeks.
To be honest, the outlook is pretty bleak for the first half of the run. We kick off on Wednesday the 29th of July with a bit of swell, but it's all over the place. A 6-foot swell from the SSE is pushing in, but it's short-period stuff, only 7 seconds, so not a lot of punch behind it. On top of that, we get hit with a thunderstorm risk and a strong onshore breeze on Wednesday morning. The whole vibe is messy. It's not until Wednesday afternoon that the wind backs off to a light offshore from the NNW, and the wave energy is still moderate (343). That afternoon window is your best shot in the near term, but it's hardly a standout.
From Thursday the 30th, the surf drops off a cliff. We're looking at tiny, weak waves for days – the energy drops into double digits and stays there. Most of the time the wind is onshore, cross-shore, or just too strong, keeping the surf choppy and uninviting. There are some windows of cleaner conditions with offshore wind, like Thursday morning and into early August, but with swell around 2 feet to 3 feet and short periods, it's just not doing anything. Honestly, from the 30th of July all the way through until around the 12th of August, you’d be doing more paddling than surfing.
There is a glimmer of something much further out. On Tuesday the 11th of August, we see a morning of clean, moderate offshore wind from the NW again, but the swell is still tiny at 2 feet. It’s not until Wednesday the 13th of August, Thursday morning, that we get a solid offshore from the WNW with clean conditions, but the swell is only 1 feet. It's pure knee-to-waist high dribble.
Given the size and conditions, there's nothing here that deserves the title of a true standout. If you're desperate, the best on offer is that Wednesday afternoon the 29th: head to Flies for some grovelly, short-period lines with a clean face thanks to the light offshore. The water temp is about average for this time of year.
For the rest of the period, it’s mostly a write-off. This is a dry spell where a lot of the energy is weak (values well under 100 for most of the second week). The moderate wave energy we see on Thursday the 30th (155) is attached to pretty ordinary conditions. It’s a classic August lull.
Signing 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.
