The Lowdown

Righto, let’s get into it. Over the next 16 days, Flies is gonna be mostly a quiet affair, so don’t get your hopes up for anything too exciting. There’s a bit of a gap early on with no real surf on offer until the morning of Wednesday the 29th, but even then it’s a bit messy.

Wednesday morning, July 29 sees a pulse of swell push in at Flies – a beach/jetty setup. We’re looking at 5 ft swell from the SSE, but the period is a short 6 seconds, so it’s pretty weak and choppy. There’s a risk of thunderstorms and the combined energy is moderate at 177. The wind is blowing onshore from the SE, so it’s gonna be rough. Not one for the beginners, as that 5 ft is getting up there.

Wednesday afternoon the swell hangs around at 6 ft from the SE, but the period stays short at 8 seconds. The combined energy jumps up to 743 (moderate), but with cross-onshore wind from the E, the conditions are only marginal. The water temperature is about 70°, a bit cooler than average for this time of year.

Thursday morning, July 30 things clean up nicely. The swell drops to 4 ft from the SSE, period 9 seconds, and the wind goes cross-offshore from the NNW, leaving the conditions clean. Combined energy is moderate at 193. This is the pick of the window – surfable waves, clean, and manageable for intermediates.

Thursday afternoon stays clean with offshore wind from the WNW, 3 ft swell from the SSE, period 8 seconds, and a moderate energy reading of 144. Still a solid option.

Friday morning, July 31 has a smaller 3 ft swell from the SSE, period 9 seconds, with a nice light cross-offshore breeze from the N. Clean conditions, combined energy 102.

Friday afternoon is glassy. Wind turns to a slight air from the WNW, 3 ft swell from the SSE, period 8 seconds, energy 101. That’s a rare treat – smooth, clean surface.

Saturday morning, August 1 is also glassy, with 3 ft swell from the S, period 8 seconds, but the energy drops to 80 (weak). Still, for a small wave session, it’s clean.

From Saturday afternoon onward, it goes pretty flat and choppy. The swell tapers off, wind picks up onshore, and combined energy readings sink into the weak zone (below 100) for days on end. There’s a gap with no real recommended surf from Sunday, August 2, all the way through to the end of the period on August 12. The occasional small clean window pops up (like Wednesday morning, August 5, with 2 ft and a clean cross-off wind), but the swell is tiny and the energy readings are pitiful (33, 26, 25, etc.). Nothing worth paddling out for.

If you’re feeling desperate, Thursday morning, July 30 is your best bet – clean, chest-to-shoulder high waves, and a bit of energy behind them. Friday afternoon’s glassy little waves are a close second for a longboard or a funboard.

Don't hold your breath for a proper session after the first week. This stretch looks more like a kite-surfing window on those choppier days.

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.
