The Lowdown
Alright, let’s get this out there. The forecast is a pretty bleak one for the next 16 days. There’s a whole lot of flatness and poor conditions to wade through, so don’t get your hopes up too early.
We’re looking at Flies (a beach/jetty setup) and honestly, the first few days are just a write-off. Saturday the 1st and Sunday the 2nd have tiny, weak swell with messy cross-onshore wind. The wave energy is barely there (73 and 80). Just not worth paddling out for.
The only real blip on the radar, and I mean the only one, is Tuesday morning the 4th. Overnight we get a pulse of 4ft swell from the south, with a decent period of 8 seconds. The wind swings to a light northerly, giving us a clean cross-off breeze. The energy is moderate (261) and the surf should actually be clean and rideable. The water temp is 71°, which is about normal for this time of year, so no wetsuit drama. That morning is your best shot, but it’s a short-lived window.
After that, it’s back to the doldrums. The swell drops off fast, and the wind turns onshore or cross-shore again. We get a few more days of small, weak swell (3ft to 5ft) but the wind is always wrong, making it choppy and lumpy. The wave energy is weak to moderate (139 to 224). The afternoon of Monday the 10th has a bit more size (6ft) but it’s a mess with a fresh cross-shore wind.
From the 11th onward, it’s all under 3ft, and the energy is pitiful. The 12th has a moment of glassy conditions, but with only 2ft of swell and 30 energy, it’s just flat. The rest of the 16 days is a long, slow slide into tiny, weak surf with nothing to get excited about.
So, to sum it up: if you’re desperate, paddle out Tuesday morning the 4th for a clean session. Otherwise, the board stays in the car. The outlook is a long, quiet gap with no real standouts for the rest of the 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.
