Table - best surf conditions forecast for Flies over the next 16 days.
Alright, Rusty here. Let’s have a look at what’s on offer.
Honestly, mate, it’s a pretty grim run for the next couple of weeks. The only spot in the mix is Flies, and it’s not looking good for a paddle. The whole 16-day window is a write-off for decent surf. We’re looking at a solid gap from the start right through to the end, with nothing worth paddling out for.
The first real chance of anything even surfable won’t come until Thursday, July 16th. Even then, it’s a weak 3 ft swell from the SSW, with a short period and light cross-offshore wind. The wave energy is a weak 65. It’s described as “surfable but very ordinary,” so you’d be scraping the barrel. The water temp is about 69°, which is a touch cooler than average for this time of year.
The one day that might get your heart rate up a little is Tuesday, July 21st. The swell picks up to 6 ft from the south, with a moderate energy of 252. But it’s all cross-onshore wind, turning it into a choppy mess. That size with that wind – it’s a messy, gutless shorebreak. For a beach/jetty setup like Flies, this is more interesting for the kite surfers than for a bloke on a log.
The rest of the days are a mix of tiny, weak swells, or bigger swells ruined by onshore wind. The wind never really gets clean for long. We see a few mornings with clean conditions, but the swell is too small to bother.
So, the honest truth: there’s nothing to get excited about. No standout. No hidden gem. Just a blank stretch of poor surf. Forecasts can change, but as it stands, keep the boards in the car and look for something else to do.
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.
