The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Flies.
Right off the bat, I gotta be straight with you – the next week and a half is looking pretty flat and bleak. The first real surf on offer doesn't show up until Monday, August 3rd, so we’ve got a long gap of over a week with nothing worth paddling out for. The water temp is about average for this time of year, so no surprises there.
We’ve got some wind shifts and a bit of background swell, but most of the time it's either too small, choppy, or just plain messy. The combined swell energy is weak for days, sitting in the low two-digit figures, which tells you there’s just no push.
The best we’re looking at is Monday, August 3rd. That morning, a solid S swell of 4ft with a 9-second period rolls in, combined energy hitting 269 (moderate) – that’s the most energy we’ll see all period. The wind is light offshore from the NW, so the wave face will be clean. The afternoon gets even better: glassy conditions with a light SW breeze, swell still at 4ft, and an 8-second period. This is about as good as it gets, but it’s still a modest wave. For a beach/jetty setup, this is actually a decent snapshot – clean, rideable, and with the offshore wind, it’ll be a lot more fun than the usual slop.
Tuesday, August 4th, still has some 3ft swell with clean conditions in the morning, but the energy drops to 123. It’s surfable, but nothing special. After that, the swell fades again and the wind turns onshore, and we’re back to small, weak waves through the rest of the second week. Friday, August 7th, onward is just tiny – 2ft to 2ft, low energy, and mostly cross-shore winds. Not worth the drive.
So, the standout here is Monday, August 3rd. It’s the only day with a proper combo of size, clean wind, and decent energy. Don’t get your hopes up for the rest of the window – it’s a long wait for one good day.
Rusty, signing off.

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.
