The Lowdown
Alright, I'm Rusty, and this is your local look at what's coming.
Gonna be honest with you, for the next few days around here, it's a tough watch. That big high-pressure system has just got the winds all wrong for us. We've got a little bit of swell hanging around, but the wind direction is just tearing it up. Most of this week is a write-off for any quality waves.
Look at Sunday morning the 19th. We've got a clean 3ft swell with a fresh offshore breeze from the NW, but the combined energy is weak at just 75. It's just not got any punch. The water temp is sitting at 71°, pretty normal for this time of year. After that, the onshore winds just chop everything to pieces through Monday and Tuesday. It's a real pain to watch.
Now, things get interesting towards the back half of next week. We go from nothing to a bit of a pulse. Wednesday the 22nd is where you want to start paying attention. The morning is a bit marginal, but by the afternoon the swell kicks up to a solid 7ft from the south, with a period of 9 seconds. The combined energy rockets up to 1258, that's strong energy for sure. The wind is a clean cross-offshore from the west. This is the standout of the whole run. Because it's that size, this is really only going to be for the experienced crew. Beginners should sit this one out.
Thursday the 23rd morning still offers some clean 4ft surf with that cross-offshore breeze, but it drops back off quickly after that. From Friday the 24th right through to the end of the first week of August, it's back to tiny, weak, and mostly onshore. There's a huge run of days there with nothing worth paddling out for.
Further out, on Monday the 3rd of August, there’s a glimmer. A 4ft swell from the SSW with a gentle offshore wind from the NW, giving clean conditions. The energy is a moderate 122. It's surfable but very ordinary. It's a long way off and forecasts could change, so don't pin your hopes on it just yet.
So, to wrap it up: the one true standout is Wednesday afternoon the 22nd at Flies. It's got the size, the power, and the right wind. It'll be clean, but expect it to be a bit of a crowd there. Everything else in this 16-day window is pretty average. Get out on that Wednesday if you can handle the size.
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.
