The Lowdown

Alright folks, Rusty here. Let’s get into it. Look, I’m not gonna sugarcoat it – the next 16 days are a real mixed bag for Flies. We’ve got a long stretch of pretty ordinary stuff to get through before anything really gets going. The water temp is sitting at 71°F, which is about 1°F cooler than usual for this time of year, so it’s a little on the fresh side, but nothing too crazy.

We start off Friday morning the 31st of July. The swell is a small 3ft from the SSE with a period of 9 seconds. The combined energy is moderate at 126. The wind is a light WNW cross-off, so conditions are looking clean. It’s surfable, but honestly, it’s very ordinary. A tiny little wave for a quick session, but don’t expect much.

From Friday afternoon, things go downhill and stay there for a solid week. The wind is all over the place, mostly cross or cross-on, and pretty strong. The swell is small and weak, with periods dropping to 6 or 7 seconds. It’s a messy, choppy, and lumpy run of days. Saturday the 1st, Sunday the 2nd, all of next week – it’s just poor conditions. The energy is low, mostly under 100. By Monday the 3rd of August, the wind hits 25 mph and the swell jumps to 7ft, but it’s a total wind-blown disaster with a fresh cross-shore chop. That’s not for paddling, that’s for the kite crew.

We get a little glimmer Tuesday the 4th of August. The morning is still a bit messy with a 5ft south swell, but the afternoon glassed right off. The wind went to 3 mph from the NE, dead calm. The wave state was glassy. The swell dropped to 4ft, period 7 seconds, and the energy was moderate at 181. It’s a marginal call, but if you’re sneaking out for a sunset session, that’s the best the first week offers.

Then silence. The 5th through the 9th of August are all poor. Small, weak, windy. Not worth paddling out.

But hold on. Monday the 10th of August is where it gets interesting. The swell jumps to 6ft from the south with a period of 9 seconds. The combined energy is strong at 533. Wind is light from the east at 3 mph, so it’s a light cross-on. The score is a 2 out of 10, so it’s still marginal, but this is the biggest, most energetic swell of the whole outlook. It’s a bit on the big side for beginners at 6ft, but for intermediates and up, there’s some real push there. The wind is light, so it’ll be ridable, but that cross-on might make it a bit lumpy. Tuesday the 11th has a brief glassy morning with a 3ft south swell, but it’s tiny.

After that, the 12th through the 15th is a slow fade into nothing. The swell drops to 1.0ft by the 14th with energy down to a pathetic 7. It’s a total flat spell.

So, what’s the standout? The one true window is Monday the 10th of August. That’s the biggest swell (6ft, S) with the most energy (533) in the whole run. It’s not perfect, but it’s the only time the ocean has any real life. Get out there if you can.

The rest of the time? It’s a long wait. The first week is a write-off, and the second week has one decent day followed by a total flat spell. For a spot that’s fairly consistent, this is a rough run. But it won’t stay this way forever.

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.
