The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Honestly, this is a grim stretch of surf ahead. The first real glimmer of hope doesn’t show up until the morning of Monday, August 3rd, so you’re looking at over a week of flat, gutless conditions. From now through the end of July and into the first few days of August, it’s a whole lot of nothing. Tiny waves, poor surf quality, and the wind is a mess. For the kite surfers, the afternoon of Wednesday, July 29th, with that 5ft cross-shore and moderate breeze, might look interesting, but for a paddle surfer, it’s a write-off.
We finally get a pulse on Monday, August 3rd. The morning session at Flies (beach/jetty) is the standout. We’ve got a clean 5ft swell from the SSE, with a 9-second period. The wind is light offshore from the north, making for clean conditions. Wave energy is moderate at 308, and it’s the most promising swell we’ve seen in days. The water is a bit colder than normal for this time of year, sitting around 70°F.
After that, Tuesday, August 4th, has a bit more size but the wind turns onshore, so it’s going to be choppy. The afternoon pushes 6ft with strong energy (668), but it’s a mess. That’s one for the experts only, and even then, it’s not ideal.
The rest of the forecast into the second week drops off again. There’s nothing else worth paddling out for. A few days with a bit of offshore wind, but the swell is too small and weak to do anything with.
So, your best bet is Monday morning, August 3rd, at Flies. It’s the only real window of clean surf, and it’s not exactly pumping. After that, it’s a long wait.
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.
