Alright folks, Rusty here. Let's have a look at what Flies has in store for us over the next couple of weeks. It’s a bit of a mixed bag, so don't expect to be wading out every day.
We’re starting with a pretty flat run. The water is sitting at 72°, which is a touch warmer than normal for this time of year, so at least it’ll feel nice while you’re sitting out there waiting. The first several days are pretty much a write-off. Sunday the 5th has next to nothing, with a tiny 1ft swell from the SSW coming in at a short 5 seconds. The wind is onshore from the ESE, making for poor conditions. Monday the 6th and Tuesday the 7th are messy with strong winds and very small, weak surf. There’s a real gap here with nothing worth paddling out for.
We finally see a glimmer of hope on Friday the 10th morning. We’ve got a clean-looking morning with a light offshore from the NNW. The swell is small, 3ft from the SSW, with moderate wave energy (67). It’s not going to blow your mind, but it’s the first time the wind is cooperating. The afternoon stays clean too, with a moderate offshore breeze. The conditions are “surfable but very ordinary”, so you can get a wet suit on, but keep your expectations in check.
Saturday the 11th sees a bump in energy, with 141 of combined swell from the SSE, but the wind turns cross-shore and cross-onshore, making it choppy and lumpy. It’s not the one. The next few days are a rinse and repeat of cross-shore winds and poor conditions, with a few clean windows on Monday the 13th morning and Thursday the 16th, but the swell is weak and the wave quality is still poor.
The one standout, and I mean the only real chance for something half-decent, looks like Friday the 17th morning. The forecast shows a 3ft swell from the S, with a period of 7 seconds, producing moderate energy (111). The wind is a gentle cross-offshore from the WSW, which should keep things clean. It’s still just “surfable but very ordinary,” but it’s the best on offer in this entire 16-day stretch. The afternoon on the 17th gets cross-onshore and choppy, so make the most of that morning session.
After that, it’s back to onshore winds and small, weak surf right through to the end of the period on the 20th, with a near gale on the morning of the 20th making things ugly. All in all, it’s a long, flat, and mostly windy outlook. That Friday the 17th morning is your best bet, but don't expect any barrels.

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.
