The Lowdown
Alright folks, Rusty here. Let’s be straight with you. Looking at the 16-day window for Flies, it’s a tough stretch. The data shows a long run of poor surf conditions, and honestly, there’s no standout session that’s going to get me fired up. Most of the time, the wind is cross-on or strong, and the swell is just too small to do anything with.
We’ve got a bit of a gap here. From Thursday the 30th of July, right through to the end of the second week, the waves are either tiny, messy, or blown out. The only whispers of anything surfable come on Friday morning, the 31st of July. The swell is a weak 3ft from the SSE, with a period of 9 seconds, and the combined energy is a modest 101. The wind is glassy though, coming from the SW at just 3 mph. That’s a major positive. The water temp is sitting at 71°, which is about 1° cooler than normal for this time of year – nothing to write home about, just a touch on the cooler side.
But even that Friday morning session is only described as "surfable but very ordinary." The break is a beach/jetty setup, exposed to the SW swell, which doesn't match the optimum direction at all. The swell is coming from the SSE, so it’s a bit of a weird angle for this spot. This is a beginner-friendly size, but the quality is just not there.
After that single window, it’s back to nothing. The following Friday morning, the 7th of August, we see another small window: 2ft from the S, period of 5 seconds, with glassy conditions from the WNW. Again, it’s described as "surfable but very ordinary." The energy is tiny at 54. It’s just not enough to make a plan around.
The rest of the 16 days? Forget it. The wind is up, the swell is down, and it’s all cross-onshore or lumpy. For the most part, the conditions are so poor that even the kite surfers would struggle to find a clean patch. The beach break setup here isn't doing us any favors.
Look, the forecast is what it is. There's no big swell coming, no clean groundswell. The best of the worst is that Friday morning on the 31st of July. If you’re desperate, paddle out for a small, clean wave, but don’t expect much. I’d say give it a rest and wait for the next weather system to change things up.
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.
