Table - best surf conditions forecast for Flies over the next 16 days.
Alright, let’s talk about Flies in feet.
So, at Flies, a beach and jetty spot, we’re looking at a long dry spell to start. The water’s about 67°F, which is a touch cooler than usual for this time of year.
From Friday the 10th of July through Sunday the 19th, it’s mostly junk. Tiny swell, short periods, bad wind. On the 14th, there’s a 3 to 5ft SW swell, but the wind messes it up and the energy is weak to moderate (44 to 138). Not worth it. That’s a week-plus of nothing good.
Things perk up Monday the 20th of July. A 3ft S swell shows up with energy at 159, and the morning wind is a fresh cross-off – clean but raw. Tuesday the 21st brings a 4ft S swell with a 9-second period and solid energy (215). The morning has clean wind from the N, so Flies might give you a few fun ones. Not epic, but it’s something.
The real standout is Wednesday the 22nd of July. That morning, Flies is firing. A clean 6 to 7ft SSE swell with a 9-second period, massive energy at 600, and glassy conditions with a light W wind. That’s the kind of session you wait for. That size is for experienced surfers, though. The afternoon goes to crap with a cross-wind, so be there early.
Thursday the 23rd and Friday the 24th keep the size up – 8ft and nearly 8ft S swell – but the wind is cross or cross-off, and the energy is very strong (up to 982). That’s expert-only, big and lumpy.
Then Saturday the 25th of July morning saves the end: a 5ft S swell, 7-second period, but glassy wind out of the WNW and moderate energy (218). Clean, fun, and a nice way to wrap things up.
The one to chase: Wednesday the 22nd of July, first light. Flies with a clean 6 to 7ft SSE swell and glassy conditions. That’s your best bet.

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.
