The Lowdown
Alright, this is Rusty. Let's have a look at what's on the cards for Flies.
Honestly, the next couple of weeks are a bit of a struggle. We’re looking at a long stretch of small, weak waves that are more about getting wet than getting a proper ride. The first decent pulse of swell doesn’t show up until Sunday the 16th, but even then, the wind is going to make a mess of it. For the most part, you’ll be waiting.
Monday 10th and Tuesday 11th are total write-offs. Tiny ankle-biters with onshore and shifting winds. Wednesday and Thursday offer some cleaner conditions with a light offshore or cross-off breeze, but the swell is barely there, around 2ft to 3ft from the S or SSW. The energy reading is weak (under 45), so it’s a kneeboard or longboard session if anything.
The whole week from the 10th to the 17th is all “poor surf conditions.” There’s a real gap in quality until Sunday the 16th. On Sunday afternoon, we see a jump in size to 6ft from the SSW (240 combined energy), which is moderate energy, but it comes with a brutal 28 mph cross-shore wind. That’s not for paddling; that’s kite territory. It’ll be lumpy, choppy, and tough.
The next glimmer is Monday the 17th. It’s still marginal, with 5ft from the S (245 energy) in the morning, but a light cross-shore wind is better. It’s not great, but it’s the most size we’ve seen with the least wind. Still, with a beach/jetty setup and the swell coming from the S (not the optimum SW), it's not going to be a standout.
Tuesday 18th has a tiny pulse of groundswell (1ft from the SE with a 15-second period). That long period is great for points and reefs, but at a beach break like Flies, it might just roll in straight and crumble. The wind is clean though, so if you’re desperate, you might find a ripple.
For the rest of the 16-day window, it’s back to small, inconsistent dribbles from the SE and E. Nothing over 3ft and mostly onshore or cross-onshore breezes. The blank run looks pretty normal for this area when the conditions don’t line up.
If I had to pick the *least bad* time to paddle out, it would be Monday morning, 17th. The swell is 5ft from the S (moderate energy at 245) and the cross-shore wind is light, which is the cleanest we'll see for that size. But keep expectations on the floor.
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.
