The Lowdown

G'day, Rusty here, and I've gotta be straight with you—this is a tough stretch for surf. The next 16 days are looking pretty bleak for any quality waves. We're in for a long dry spell, with only a couple of brief windows where the surf might just be worth a look, but nothing to get too excited about. This kind of blank run isn't unusual for the area, so don't be too disheartened; forecasts can always change.

Let's start with the first real chance, which is on Wednesday, July 22nd. The swell is coming in from the South at 7ft, but it's a short-period 8-second wind swell, so it's gonna be a bit fat and lacking punch. The real problem is the wind. Wednesday morning has a cross-offshore breeze from the WSW at 16 mph, which at least keeps the surface clean, but the combined swell energy is moderate at 692. By the afternoon, the wind swings to the SSW at 22 mph, turning it into a lumpy mess. This is a marginal call at best.

Then we get a brief glimmer on Thursday, July 23rd. The morning starts clean with a cross-offshore breeze from the NNW at 16 mph, and 6ft of South swell (9-second period) with a moderate combined energy of 509. But the real standout is Thursday afternoon. The wind goes offshore from the NW at a light 6 mph, and the swell drops to 5ft from the South, with an 8-second period. The combined energy is still moderate at 302. This is the best session on offer—clean, glassy conditions and a decent wave for an intermediate surfer. It's not going to be a world-beater, but it's the pick of the bunch.

After that, we're back to small, weak, and messy. The swell drops right off on Friday, July 24th, with 3ft from the South and a 3 mph cross-offshore breeze in the morning making it clean, but the energy is weak at 152. It's surfable, but nothing special. The next real chance doesn't come until Wednesday, July 29th in the afternoon. The wind swings offshore from the NNW at 9 mph, and we get a 5ft South swell with a much longer 10-second period, giving it a bit more grunt. The combined energy is moderate at 474. This is promising, but it's over a week away, so treat it as a maybe.

Thursday, July 30th morning also looks clean with a cross-offshore breeze from the West at 9 mph, and 4ft of South swell (9-second period) with a moderate combined energy of 274. Worth a look if you're keen.

The rest of the forecast is dominated by small, onshore, choppy slop, with the swell barely reaching 4ft for most of it. The water temperature is about average for this time of year, sitting at 71°F.

So, to wrap it up: Thursday, July 23rd afternoon is your best bet for clean, surfable waves. Wednesday, July 29th afternoon is the long-range promise, but don't hold your breath. The rest is a write-off.

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.
