Table - best surf conditions forecast for Flies over the next 16 days.
Rusty here again, and it's a bleak 16 days for the paddle crew. The first ten days or so, from Saturday the 11th up to the 24th, are a flat-out no-go. The swell is tiny, often under 2 feet and mostly gutless with short periods. The energy just isn't there.
The only period with any size shows up on the 25th of July. By Saturday morning, we're seeing swell around 5.2 ft, building to 5.6 ft in the afternoon, with a period of 9-10 seconds. The combined energy will climb to 443-501 (strong), but that power is wasted. The wind is pretty hectic, blowing from the ENE at 19-22 mph, putting a cross-onshore texture all over it. It'll be lumpy and tough. Sunday the 26th looks a little better, with the swell holding around 5 ft, a clean face from a cross-offshore NNE breeze at 16 mph. That's the best the window offers, but the swell direction is from the SSE, which is off-angle for what Flies wants out of the southwest. With the size pushing 5 ft, it's getting on for the bigger end of intermediate territory too. It's just not the kind of combo that makes you want to call in sick. I'd be saving the energy for another 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.
