The Lowdown
Right then, let’s have a look at what’s on offer for Flies (Flies).
Honestly, it’s a pretty tough stretch. The guidance file flags Flies as a fairly consistent spot, and it’s usually worth a look when the swell direction is right, but this 16-day window is a real struggle. There’s a big gap of poor surf right from the start, and it just keeps going.
The first real flicker of something surfable doesn’t show up until Monday afternoon of the 3rd of August, but that’s a mistake. The wind is a fresh cross-shore at 19 mph, the swell is a messy 8ft from the south at 9 seconds, and the combined energy is strong (1631). It’s a stormy, lumpy mess. Not for paddling.
The first time you might actually get a wave is Tuesday morning, the 4th of August. The wind goes glassy, swinging to the northeast at just 3 mph, and the swell drops to 4ft from the south at 8 seconds. The combined energy is moderate (196). It’s not big, but it’s clean. The water temperature is about average for the time of year at 72°F.
After that, it’s a desert. From Tuesday afternoon right through until Wednesday morning of the 12th of August, it’s nine days of poor surf conditions. Small swell, bad wind, cross-chop – the whole lot. There’s a brief moment on Wednesday afternoon of the 12th of August when the wind goes offshore from the northwest at 6 mph, and the swell is 4ft from the southwest at a short 5 seconds. The combined energy is weak (67). It’s clean, but those waves are going to be weak and gutless. Not a standout.
The rest of the window is just flat or onshore slop. The swell barely reaches 2ft for most of it, and the wind is often strong and cross or cross-onshore.
So, if you’re desperate for a paddle, Tuesday morning the 4th of August is your best bet. It’s the only time you’ll get glassy conditions and a clean wave, even if it’s small. The rest? Honestly, it’s more of a kite-surfing setup on those windy, lumpy days than anything for a surfboard. The forecasts can change, but right now, this is a lean run.

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.
