The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
We’ve got one spot in the mix, Flies, and honestly, it’s a bit of a mixed bag. The whole period is a slow burn with very few clear windows. There’s a long gap with nothing worthwhile from the start until we get a few brief moments of hope. The first real surf that’s worth paddling out for doesn’t show up until the morning of Thursday the 30th of July. After that, there’s another quiet period, with the next best look being a week later, around Tuesday morning, the 4th of August.
The standout session is Thursday morning, 30th July at Flies. You’ve got a clean 4ft swell from the south with a 9-second period, which has some decent energy behind it (240). The key is the light westerly cross-offshore wind, which is going to keep the surface glassy. This is the best looking window on the whole run. If you’re keen, that’s the one to aim for. The water temp is about average for the time of year, nothing weird going on.
The other moment that’s worth a mention is Tuesday morning, 4th August. It’s a full week later, so keep that in mind. The swell is a similar 4ft from the south, but the period is shorter at 7 seconds, so it won’t have the same push as the 30th. The energy is moderate (130), and the cross-off wind from the west-northwest should keep it clean. It’s a respectable option, but not as punchy as that Thursday.
Everything else in between is a write-off. We get a few pulses of 5ft swell on the afternoon of the 28th of July, but the cross-shore to onshore winds and a choppy surface ruin it for proper surfing. The small stuff later in the run is too weak and messy to bother with.
So, to sum it up: Flies has its moments, but they’re short and sweet. If you’re stuck for a paddle, the window on the 30th is your best bet.
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.
