The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
It’s a lean start, I’m not gonna lie. The first week or so is pretty much a write-off. We’re looking at days of tiny, onshore slop with barely enough energy to move a sea-lion, let alone a surfer. From Sunday the 26th of July right through to the end of the month, it’s all poor surf conditions with weak swell and wind from the wrong quarter. The water is a bit colder than usual at 69°, about a degree and a half off the norm.
The first real hint of something better shows up on Monday the 3rd of August. The swell starts to build, but it’s still messy. By Thursday the 6th of August in the morning, we get a sniff of something clean with a light offshore from the NNW, but the swell is small at 3ft, and the energy is weak (58). It’s surfable, but only just.
Now, the standout. Friday the 7th of August is the one to circle on the calendar. Flies is the only break in the game here, and it’s going to wake up. The morning brings a clean 7ft swell from the SSW with a moderate cross-offshore breeze from the north. The combined energy is strong (817). That’s proper groundswell energy, and with the period at 8 seconds, it’s got some shape to it. The afternoon goes glassy with a 7ft SSW swell, clean as a whistle. The wind goes dead calm, light from the SW – that’s glassy conditions. This is easily the best on offer. The crowds are sometimes an issue here, so be ready for company, but for a Friday, it’s worth the paddle. The swell is over 5ft, so it’s not for beginners, but for intermediates who can handle a bit of push, it’ll be a treat.
Saturday the 8th of August morning still has some clean leftover energy from the north at 5ft, but it fades fast. After that, it’s back to small, onshore mush for the rest of the run.
So, the long story short: grin and bear the flat spell, then hit Flies on Friday the 7th of August. That’s the only real window.

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.
