The Lowdown

G’day, Rusty here, and I’ve gotta be straight with you – the next couple of weeks at Flies (beach/jetty) are looking pretty grim. There’s a long stretch of poor surf conditions ahead, so don’t get your hopes up for anything decent for a while.

We’ve got a real dry spell on our hands. From Wednesday, 15 July right through to the end of Saturday, 18 July, it’s almost all “poor surf conditions” with tiny swell, mostly below 2 ft, and weak energy (readings often in the teens to low 30s). The wind is mostly cross-off or cross-on, but the swell just isn’t there. Thursday morning, 16 July, you’ve got a 2 ft S swell at 6 seconds, but the combined energy is a measly 36 – not worth paddling out for.

The only glimmer comes on Sunday, 19 July, with a morning pulse of 5 ft SSW swell at 7 seconds, and the combined energy jumps to 345 (moderate). The wind is clean cross-off from the W at 12 mph, so it’ll be tidy. But it’s still only a marginal forecast – the score is a 1 out of 10, and by afternoon it drops back to poor. Not a standout, just a brief window of okay-ish waves.

Then on Monday, 20 July, the swell bumps up to 5-5 ft S at 9 seconds, with energy hitting 383-434, but the wind turns onshore or cross-on from the E/SE, making it choppy and messy – poor conditions again.

The real highlight, if you can call it that, is Wednesday, 22 July. The morning delivers a 6 ft S swell at 9 seconds, with combined energy of 471 (moderate) and a clean offshore wind from the NW at 9 mph. That’s the best on offer – the only time we see “expect good surf conditions” with a score of 2. The swell size is 6 ft, which is solid for intermediates, but it’s not too big for most. The 9-second period gives decent shape, and with offshore winds, it’ll be clean. Crowds are “sometimes” here, so you might have a few others around, but it’s worth a look. After that, it’s back to poor surf and small, weak swell for the rest of the month.

The water temperature is 71°F, which is just 0.2°F above the long-term average – pretty normal for this time of year, nothing unusual.

So, bottom line: the only true chance for a paddle is the morning of Wednesday, 22 July. The rest of the 16-day window is a write-off – small, weak, and wind-affected. There’s a solid gap of poor days before and after that one window. Don’t hold your breath, but forecasts can change.

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.
