The Lowdown

G’day, Rusty here. Looking at the next couple of weeks, it’s a pretty bleak stretch for a surf, to be honest. We’ve got a long run of small, wind-affected slop ahead before things finally line up for one proper session. There’s a real dry spell from now until the second week, so if you’re keen, you’ll be waiting a while.

The first real chance of anything decent doesn’t show up until the morning of Sunday the 10th. We finally see a bit of energy come through, with a 5ft swell from the SSW and a period of 7 seconds. The wind is cross-offshore and clean, so it should be surfable, but the energy is still moderate, sitting at 327. It’s not going to be a classic, but it’s the best offer in that first stretch. The swell direction is a touch off the optimum, and it’s fairly inconsistent, so don’t expect a lot of waves, but it’ll be the pick of a bad bunch. After that, it’s back to the small stuff with cross-shore winds and poor conditions right through to the following week.

There’s a few mornings with clean cross-off winds, like the 11th and 12th, but the swell is just too small to get excited about. It’s one of those frustrating periods where the conditions look okay but there’s nothing pushing in.

Now, here’s the standout. The morning of Saturday the 15th. This is the one we’ve been waiting for. The swell jumps to a solid 7ft from the SSW, with an 8-second period. The energy is strong, with a reading of 1062. The wind is dead calm and it’s glassy. This is excellent surf for experienced surfers. The size is pushing into the territory where beginners should sit it out, but for the rest of us, this is the morning to be in the water. The swell direction is right on the money, and the glassy conditions will make it clean as a whistle. This is the standout of the whole period, no doubt. The period is a bit short, so it might be a little crumbly, but the combination of size and clean conditions makes it the clear winner.

After that, the energy drops right back off and we’re back to the small, choppy stuff for the rest of the period. The water temp is sitting at 72°, which is pretty much average for this time of year, so no dramas there.

So, the call is simple. Wait for the 15th. That Saturday morning is the one. The rest of the fortnight is a write-off for a proper paddle. If you’ve got a kite, those days with the bigger swell and cross-shore winds might be more interesting, but for surfboards, it’s a waiting game.

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.
