The Lowdown
Alright mate, let’s take a look at what’s cookin’ for Flies. Gotta be honest, it’s a pretty quiet spell ahead. These next couple of weeks aren’t gonna light any fires.
Water temp is about 69°, which is a touch cooler than normal for the season. Feels a bit nippy.
For the first week, from Sunday the 26th through to about Wednesday the 30th, it’s mostly onshore junk. Swell is tiny – ankle to knee high – with weak energy (combined energy mostly under 70). Winds are cross or onshore, making it choppy and messy. Not worth wettin’ a suit.
Thursday the 30th shows a glimmer: cross-off wind from the NNE cleans things up, with swell around 3 to 4 feet (SSE, 8–9 seconds). Energy hits 361 that afternoon – that’s moderate energy – and it looks clean. That’s a window.
Friday the 31st morning stays clean and cross-off, with 3-foot S swell (9 seconds, energy 227). Still only marginal, but better. Then Friday afternoon we get deadly glass – wind drops to around 3 mph from the WNW, flat calm, and 4-foot NE swell rolls in. Energy’s 196. It’s not epic, but glassy conditions will make it fun.
Saturday the 1st of August starts totally glassy, dead calm, with 3-foot S swell (8 seconds). Energy is low at 88, but it’ll be clean and uncrowded – crowds here only happen “sometimes.” That’s a solid morning to just float around.
After that, it’s back to small, weak, and mostly wind-affected. There are a couple more clean bumps – like Monday the 3rd morning with glass and 3-foot S swell – but nothing special. The second week is a write-off: tiny swell, onshore winds, energy in the teens and twenties.
Your standout sessions are Friday 31st afternoon for the glassy 4-foot NE swell, and Saturday 1st morning for a flat-calm, small-wave morning. Don’t expect any pumping groundswell – this is a mellow stretch.

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.
