The Lowdown
Hey, Rusty here. Let’s get into what’s coming for Flies.
The first few days are flat or blown out, so don’t rush out. You’re looking at a dry spell until Monday the 17th. Friday the 14th has tiny 1ft waves with cross-off winds that don’t help, and the afternoon goes to hell with a cross-on. Saturday the 15th and Sunday the 16th are even smaller—hardly worth a look.
The real standout pops up on Monday the 17th in the morning. There’s a 6ft SSE pulse (energy 361) hitting with offshore wind from the WNW at 12 mph. It’s clean and punchy. This one’s for the experienced crew—over 5ft is expert territory. Intermediate surfers will be fine if they’re hungry. Water’s at 75°, which is a little warmer than usual for the season.
After that, Tuesday the 18th and Wednesday the 19th go small and choppy again. Thursday the 20th brings a chest-high swell at 4ft from the S with a light cross-off breeze, keeping things tidy. It’s surfable but not special.
From Friday the 21st through to the middle of the following week, it’s mostly tiny and onshore. Tuesday the 25th morning shows a 4ft SW swell with clean cross-off wind (energy 99)—still mediocre. Thursday the 27th has a bit more energy (115) but cross-on wind kills it.
The best session of the whole 16 days is Monday the 17th. Get on it if you can. Otherwise, the beach/jetty setup might be more inviting for the kite crowd on the onshore days.
That’s your lot from Flies.
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.
