Right then, let’s have a look at what’s on offer for Flies (beach/jetty) over the next couple of weeks.

It’s a tough start, honest. The first few days are a write-off. Monday the 13th and Tuesday the 14th are flat and messy, no good for a paddle. We’ve got a bit of a gap there until things start to show a pulse.

Wednesday the 15th morning is where it finally gets interesting. The swell bumps up to 5ft from the SW, with a weak 6-second period, but the wind is a light cross-off breeze from the WNW. The combined energy is moderate (241), and it’ll be clean. It’s not a classic, but it’s the first real chance to get wet. The afternoon drops off a bit, but still clean.

Thursday the 16th through to Monday the 20th is a real mixed bag of onshore junk and small swell. Not worth your time. The best of a bad lot looks like Wednesday the 22nd morning. The swell is 4ft from the S, period up to 8 seconds, with a gentle offshore from the NW. The combined energy is moderate (215) and it’ll be clean. That’s the standout. It’s a fairly consistent spot, so it tends not to stay flat for too long, but this run is poor.

After that, it’s back to small, choppy cross-on slop for the rest of the window. The water temp is about average for the time of year, nothing unusual.

Honestly, if you’re desperate, Wednesday the 22nd morning is your best bet. Otherwise, it’s a long blank spell.

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.
