Table - best surf conditions forecast for Flies over the next 16 days.
Alright, this is Rusty. Let's have a look at what's on the table for Flies over the next couple of weeks.
Honestly, it's a pretty grim stretch ahead. The first week and a half or so is basically a write-off, and then we get a pulse of serious size that's totally blown out. We're looking at a near two-week run with no real standout sessions on offer.
The first real chance of anything ridable doesn't show up until Wednesday, July 15th. That morning, we've got a tiny 3ft swell from the SSW, but at least the wind is light and clean. The wave energy is weak (76), and the conditions are just described as "ordinary." It's better than nothing, but it's not going to get the heart racing.
The only thing that stands out as significant is what happens on Tuesday, July 21st. The swell jumps up to 7ft on the morning, and then 10ft in the afternoon from the SSE. The combined energy rockets up to 301 and then 1033, so there's plenty of power. But here's the catch – the wind is cross-onshore and choppy both times. That much swell with that wind is going to be a messy, lumpy beast. It's one for the experts only, and even then, it's going to be a battle. The water temp is about 72°, which is a touch warmer than average for this time of year.
For the rest of the run, it's mostly tiny, weak, and onshore. There's a glassy, calm morning on Monday, July 20th, but the swell is a pathetic 0.3ft with nothing behind it. You'd be better off with a longboard and a lot of patience.
All in all, there's nothing to get excited about here. The swell that shows up is either too small or too messy to really recommend. Better luck next time.
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.
