Table - best surf conditions forecast for Flies over the next 16 days.
Alright, Rusty here. Let’s have a look at what’s cookin’.
Well, I gotta be straight with you—this is a tough stretch for Flies (beach/jetty). It’s a bleak outlook for the next 16 days. We’ve got a massive gap of absolutely nothing rideable from now until the morning of Wednesday, July 15th. That’s like a week of flat or junk. The water temp is sitting at 68.7°F, which is pretty average for this time of year, so cold won’t be your excuse for staying out.
Wednesday morning, July 15th, sees the first little pulse of life. The swell pushes in at 3.9ft from the SSW, with a period of 6 seconds, so it’s short-period wind swell. The combined energy is weak, sitting at 117. It’s surfable but nothing to write home about. Winds are light cross-offshore, keeping things clean, but it’s still pretty ordinary.
Thursday the 16th is actually smaller and cleaner, with WSW winds and a little 2.3ft SSW swell. Still, it’s not going to thrill anyone.
The real standout comes on Monday, July 20th. A solid pulse of 4.9ft to 6.6ft SSW swell rolls in with moderate combined energy (153 to 335). That’s the biggest swell of the whole period. BUT—here’s the heartbreaker—it’s blowing onshore from the ESE and SE with choppy, messy conditions. At that size, this beach setup is going to be a washing machine. Not your day for a paddle; looks more interesting for kite surfing than a clean surf.
Tuesday the 21st morning offers the best chance you’ll get: a 5.6ft S swell (253 combined energy) with light SSE cross-onshore winds. It’s still marginal, but the energy is solid and the wind is light enough you might find something workable if you’re an expert. The short 6-second period means it’ll be dumpy and sectiony though.
After that, it fades fast. By Wednesday the 22nd, the swell drops back under 3.6ft, and we’re back into cross and cross-onshore winds for the rest of the window. Nothing worth chasing.
Bottom line: the only real chance to get wet here is Tuesday morning, July 21st, at Flies, with that S swell and light winds—but don’t expect gems. It’s a lean, mean stretch.
Stay patient, folks.

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.
