The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a long-range look at Flies (beach/jetty) for the next couple of weeks, and honestly, we’re going to be waiting a while for anything worth paddling out for. The first real sign of life doesn’t show up until Wednesday, July 22nd, and even that’s a bit of a tease. The week before that is a flat, windy mess, so plan on doing something else. The water temp is sitting at 70°, which is about normal for this time of year.
The first standout that catches my eye is the morning of Tuesday, July 28th. We’ve got a solid 7ft swell coming from the south, with a clean offshore breeze from the NW. The combined energy is up there at 364 – that’s some proper juice. The wind is going to groom it nicely, making for clean, powerful lines. The downside is the period is only 7 seconds, so it’s a bit of a windswell, but with that size and clean conditions, it’ll be the best of the run. This one’s for the experienced crew; 7ft is getting into expert territory, especially on a beach break.
The afternoon of the 28th drops off a bit to 4ft but stays clean with a cross-off breeze. The morning of the 29th has some firing offshore wind, but it’s on a tiny 3ft swell with weak energy (49), so it’s more of a longboard day.
The previous week, Wednesday July 22nd morning offers up a 6ft S swell with a cross-off breeze and a stacked energy reading of 614, but it’s only given a marginal score. That’s a lot of water, but the wind is cross-off, not pure offshore, so it might be a bit lumpy. Still, for the bold, it’s the biggest swell of the entire period.
Bottom line: if you’re a competent surfer, circle the morning of Tuesday, July 28th. It’s the best trade-off of size, wind, and shape we’re going to get. The rest of the window is either too small, too windy, or too messy to get excited about.

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.
