The Lowdown
Alright, Rusty here, let’s break down what’s in store for the next couple of weeks.
Honestly, it’s a slow start. We’re looking at a long stretch of days with hardly anything worth paddling out for. The first real chance to get wet comes on Tuesday the 4th of August, and even that’s a short window.
The one and only standout is the Tuesday morning session on the 4th of August. We’ve got a clean 4ft swell from the south, with a period of 8 seconds, giving a moderate combined energy of 250. The wind is a light cross-offshore from the NNE at 6 mph, which is going to keep the surface glassy. The water temp is at 72°, which is about normal for this time of year. That’s your best bet. The break is Flies. It’s a beach/jetty setup and fairly consistent, but it can get crowded sometimes. The swell direction is from the south, and the optimum is from the southwest, so the angle isn’t perfect, but with the clean conditions, it’ll still be fun for intermediate surfers. That afternoon, the wind swings onshore and the swell drops, so don’t stay out late.
After that, it’s a long dry spell. From Tuesday afternoon right through to Tuesday the 18th of August, the surf is mostly poor. There are a few mornings where it’s surfable but very ordinary, like Wednesday the 5th, Thursday the 6th, and Saturday the 8th, with small, weak swells around 2ft to 3ft, and short periods under 8 seconds. The wind is often cross or cross-off, but the energy is just too low. The combined energy rarely breaks 100, often sitting in the 50-90 range. It’s flat, weak, and choppy.
Things pick up again on Wednesday the 19th of August, but it’s a different story. The swell jumps to 5ft from the southwest, with a combined energy of 193, but it’s completely blown out. The wind is a strong cross-shore from the SW at 22 mph, making a messy, lumpy cross-chop. That’s not a paddle surf day; that setup looks more interesting for kite surfing than paddle surfing. The period is only 6 seconds, so it’s just windswell. The afternoon gets even worse, with the wind hitting 25 mph. This one is for experts only, and even then, it’s going to be a battle.
So, to wrap it up: Tuesday morning on the 4th of August is your one real shot. The rest is a long, flat wait with a nasty, windy end.
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.
