The Lowdown
Alright folks, Rusty here. Let's get stuck into what's on offer at Flies. We've got a bit of a mixed bag coming up, so let's break it down.
First up, the water temp is sitting at 70°, which is about a degree and a half cooler than what we'd normally expect for this time of year – a little nippier than usual, so don't forget the booties if you're heading out early.
The first proper window to talk about is Thursday morning, July 30th. We've got a 4ft swell rolling in from the SSE with a period of 9 seconds, giving us a moderate wave energy (217). That's a solid groundswell, and with a light offshore wind from the NNW, it's going to be clean. It's not massive, but it's the best looking surf in the near term, and the conditions will be good.
After that, the surf gets pretty ordinary. We run into a stretch of days with messy, onshore winds and small, weak swell. Friday morning holds a tiny 3ft SSE swell, but the wind is offshore and light, so it's surfable, but nothing to write home about. Then we hit a real dry spell from Friday afternoon all the way through the first week of August. There's a lot of poor conditions with moderate to fresh cross-onshore winds and choppy surf. The swell is small and the period is short, making for weak, unappealing waves. This lull is a solid week of nothing special.
Now, the real standout is a bit further out, but it's promising. Sunday, August 9th is looking like the pick of the whole forecast. The swell is building. By the morning, we're looking at a 6ft SSW swell, and the wind is a light offshore from the NW. The morning session will be clean. Then the afternoon picks up with a 7ft swell from the same direction, a moderate wave energy (394), and a light cross-offshore breeze. That's a solid amount of swell with clean conditions. It's getting up there in size, so for the more experienced surfers, this is the one to circle. Beginners might find it a bit much.
The following day, Monday, August 10th, also has a 7ft SSW swell in the morning with a very strong wave energy (677), but the wind is a light cross-shore, so it's a bit less clean. Still, if you're an expert, that's a lot of power to play with.
So, to sum it up: the best surf is on Sunday, August 9th, with the 7ft SSW swell and clean conditions. Thursday morning, July 30th, is your best bet in the short term. The gap in between is a long, flat stretch, so keep your expectations in check until we get to that second weekend.
Stay safe out there.
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.
