The Lowdown
Alright, let’s keep it real. The next couple weeks are looking pretty bleak for waves. We’re talking a long stretch of small, weak surf with shifty winds, so don’t get your hopes up. There is one little window later on that looks promising, but it’s a ways out.
The first real chance you’ll get is on Thursday, the 14th of August. The morning’s the best bet—about 4ft of SSW swell with a clean offshore breeze. It’s not going to be firing, but it’s the first time the conditions will actually line up for a decent paddle. The energy is still pretty weak though, so it’s more about scoring a few fun ones than anything epic.
Then we slip back into a few days of flat, messy conditions. Through the weekend and into early next week, the ocean’s just not giving us much. The 19th brings a bit more size—up to about 5ft—but it’s all chopped up with onshore winds, so the quality is gone. It’s one of those days where it looks like there’s something out there, but it’s just a mess.
Now, the standout. On the morning of Wednesday, the 20th of August, we get the best conditions we’ll see in this whole stretch. There’s 5ft of SSW swell, a cross-off wind, and the energy jumps up to a solid 372 units. The break is Flies, a beach and jetty setup that can handle this size. The wind is light and clean, so it should hold shape. This is the one to circle on the calendar. Later that afternoon, the wind turns offshore and it’s still around 3ft, so there’s a chance for a session then too, but the morning is the prime time.
After that, it fades out pretty quickly. The rest of the week drops way down, back to knee-high slop with cross-shore winds. By the 23rd, we’re looking at about 2ft and weak energy, so it’s time to wax the log, or maybe just take a break.
One thing to note: the water temp is about 74°F, which is a touch warmer than usual for this time of year. Not a huge deal, but you might not need the thickest wetsuit.
In short, if you’re chasing waves, wait for the morning of the 20th. That’s the one. It’s more than a week out, so don’t hold your breath, but it’s the only real window we’ve got. Otherwise, it’s a whole lot of nothing.

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.
