The Lowdown

G’day, Rusty here. Look, I’ll be straight with you – the next 16 days at Flies are a real mixed bag, and we’ve got to wade through a lot of ordinary to find the one moment that’s worth paddling out for. The pattern starts quiet, builds to a solid pulse mid-week, then fades back into a long stretch of nothing special.

We kick off on Monday, July 20th, with tiny surf. The morning has a weak 3 ft south swell at a short 7 seconds, and the combined energy is a weak 76. It’s glassy, which is nice, but there’s just no oomph. That afternoon, the wind swings south and kills it completely – 2 ft and onshore. Don’t bother.

Tuesday, July 21st, is a write-off. Strong onshore winds from the SE at 19 mph, building a bit of bumpy 4 ft to 4 ft south swell, but the period is a pathetic 5 to 6 seconds. The energy is still low (80 to 112). It’s lumpy, messy, and not worth your time.

Now, here’s the standout. Wednesday, July 22nd. The morning is tricky – a 8 ft south swell with a 9-second period arrives, but the wind is a strong cross-offshore at 19 mph, and the energy is already a moderate 846. It’s clean, but that wind is a handful. The real magic happens Wednesday afternoon. The swell holds at 8 ft south, period still 9 seconds, but the wind drops to a gentle 9 mph cross-offshore. The combined energy jumps to a very strong 1573 (moderate to strong wave energy). The water temp is about average for the time of year. This is the window for experienced surfers only – 8 ft is big, and the power is there. The south swell direction is a good match for the optimum SW direction. The break is a beach/jetty setup, so it’s exposed and will handle that energy. It’s fairly consistent here, and crowds are possible. This is the best on offer, no question.

Thursday, July 23rd, drops off quickly. Morning sees 4 ft south swell with an 8-second period, clean with a cross-offshore wind, but the energy is only 239, and it’s described as marginal. The afternoon is 4 ft and cross-shore, still not great. From Friday, July 24th, right through to Tuesday, August 4th, it’s a long, flat goodbye. You’ll see small south swells in the 2 ft to 5 ft range, but the periods are short (5 to 8 seconds), the winds are mostly onshore or cross, and the energy is weak (25 to 161). There are a few clean mornings (like July 29th and 30th) with offshore winds, but the swell is too small to do anything – 2 ft to 2 ft. It’s a nine-day gap with no real recommendations. The occasional “surfable but very ordinary” comment sums it up. For a beach/jetty, this stretch is more interesting for kite surfers than paddle surfers, given the strong cross-on winds and lumpy conditions on days like July 27th and 28th.

So, if you’re keen, you’ve got one shot: Wednesday afternoon, July 22nd. It’s big, it’s powerful, and it’s clean. For the rest, it’s a long wait. Forecasts can change, but right now, it’s slim pickings.

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.
