The Lowdown
Alright folks, Rusty here. Let’s get real about the next couple of weeks at Flies (beach/jetty). It’s a pretty grim stretch, so I’ll level with you.
We’re looking at a long, drawn-out period with very little to get excited about. The surf is small, the wind is often messy, and the overall energy is weak. For the first few days, we’ve got strong onshore winds and rain, making for a right mess. Tuesday the 28th sees a 3ft SSW swell, but with a short 5-second period and a cross-on wind, it’s just choppy and poor. That pattern holds through Wednesday the 29th, with a slightly bigger 5ft SSE swell on the morning but still borderline unsurfable due to the wind and rain.
The first real glimpse of something surfable comes on Thursday the 30th. The morning sees a 4ft SSE swell with a 9-second period, and the wind swings to a clean cross-off. The combined energy is moderate (179), and the waves will be clean. It’s nothing special, but it’s the first real chance to get wet. The water temp is 70°F, which is a bit colder than normal for this time of year, so you might want a spring suit.
The real standout, if you can call it that, is Friday the 31st. The morning has a 3ft SSE swell, still with a decent 9-second period, and light cross-off winds. The afternoon, however, is the best of the whole run. The wind goes glassy with a 3ft SSE swell. It’s small, but it’ll be clean and might offer a few fun little runners. The combined energy is weak (87), so don’t expect any power, but for a quiet paddle, it’s your best bet.
After that, it’s back to the doldrums. From Saturday the 1st of August all the way through to the 12th, the swell stays tiny, mostly under 3ft, with periods often under 8 seconds. The wind is rarely in your favour, blowing cross-on or onshore for most of it. There are a few moments with clean cross-off winds on the 4th and 7th of August, but the swell is too small and weak to do much with. The combined energy on those days is barely breaking 80, which is weak.
This is a classic case of a long flat spell. The break is fairly consistent, but it’s just not getting any power. The best advice? If you’re desperate, chase the glassy window on Friday the 31st afternoon. Otherwise, save your energy. The forecasts can change, but right now, 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.
