The Lowdown

G’day, Rusty here. Look, I’ll be straight with you – the next sixteen days at Flies are a real mixed bag, and for the most part, it’s pretty quiet. The water’s a touch warmer than normal for this time of year, sitting at 76°F.

The first week and a bit is a write-off. From Wednesday the 12th right through to the morning of Saturday the 22nd, we’re looking at a long stretch of barely any surf. The combined swell energy is weak, mostly under 100 (21 to 104), and the wave heights are tiny – mostly under 3ft. The wind is all over the shop, too, with a lot of cross-off and cross-onshore slop. It’s just not worth paddling out. You’ll be sitting there bobbing around on nothing.

The one true standout in this whole period is the afternoon of Saturday the 22nd of August. Finally, a bit of life! Flies (beach/jetty) will see a 5ft SSW swell, with a period of 7 seconds. The combined energy climbs to a moderate 238. The wind goes glassy – flat calm – and that’s a major positive. The waves will be super clean. The swell is a bit small for the size, but for a session with no wind and a little push, it’s the best on offer. Be aware, it’s an exposed spot and the optimum swell direction is SW, so this SSW swell is a good match. Crowds are sometimes a problem here, so you might have a few mates out.

The Sunday morning the 23rd also has a glassy start with 4ft SSW swell, but the energy drops to 110 and the conditions are just “ordinary” – not the same quality as the Saturday arvo. After that, it’s back to small, messy stuff through to the end of the month.

So, my call: if you’ve got a window, make it the afternoon of the 22nd. That’s your one real chance for a decent, clean wave. The rest of the run is a waiting game.

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.
