Table - best surf conditions forecast for Flies over the next 16 days.


Alright, Rusty here again, but this time in feet and degrees Fahrenheit for you.

Let’s be real – the next couple of weeks look pretty flat and messy for the Flies (beach/jetty). Water temp is about 72°, which feels a touch warmer than usual for this time of year.

The first little blip of surfable waves shows up on Wednesday, July 15th in the morning. We’re talking about 0.3ft SSW swell with a 6-second period, and offshore wind from the NW at around 9 mph. The energy is still low at 67, and conditions are just “surfable but very ordinary.” It’s not a standout, just the first break in the quiet.

Then we wait again until Sunday, July 19th in the morning. That’s the one to keep an eye on. The Flies go glassy with a light NNW breeze, and a 0.3ft SSE swell comes in with an 8-second period. The combined energy jumps to 120 – moderate – and the conditions are clean. The morning window looks like the best of the whole run: glassy, a little push from the SSE, and your best chance at a few clean lines.

Sunday afternoon the wind swings onshore and the swell pushes to 0.4ft, but the energy hits 255. That’s a lot of juice, but the cross-on wind will chop it up. Not for beginners, but an experienced surfer might find a few.

Monday, July 20th morning keeps it interesting with 0.4ft SSE groundswell (9-second period) and light cross-shore wind. Energy is a solid 227. It’s marked as “marginal” due to tide, so you’ll need to time it right.

After that, it’s back to lumpy cross-shore chop through the end of the period, with winds 15-22 mph and waves around 0.3-0.4ft. Not much to get excited about.

The single standout? Sunday morning July 19th at Flies – glassy, clean, and the best chance at a few proper waves. It’s not a classic, but it’s the best on offer.

Stay patient, man. The ocean’s been quiet.

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.
