The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on offer for the next sixteen days at Flies. Gotta be straight with you – it’s gonna be a tough wait. We’re looking at a long stretch of pretty average conditions before we finally get a sniff of something worthwhile.

The first solid recommendation doesn’t show up until Thursday, July 30th, and even then it’s a bit of a tease. For the first five days, from Friday the 24th right through to Tuesday the 29th, it’s a whole lot of nothing. The wave energy is weak, mostly sitting between 1 and 89 (combined energy), with onshore or cross-shore winds chopping up any tiny swell that tries to show. It’s frustrating, but that’s the way it goes sometimes.

Thursday morning, July 30th, is where we finally get a little glimmer. The swell bumps up to 3 ft from the south with an 8-second period, and crucially, we get a light offshore breeze from the north. The combined energy hits 144 (moderate), and the conditions are clean. It’s not pumping, but it’s surfable. The waves are very ordinary, but for a patient soul on a longboard, it’s a paddle. The water temp is about average for the time of year, so no shock to the system there.

Friday morning, July 31st, is similar – 3 ft from the south-southeast, clean with a north-northeasterly cross-offshore breeze. The energy is back up to 105 (moderate), but again, it’s just ordinary surf. You’ll get a few fun ones, but nothing to write home about.

The real standout, the one I’d circle on the calendar, is Friday morning, August 7th. That’s a full week away, so keep your expectations in check, but the data’s got me excited. We get a 5 ft swell from the south, with a light offshore wind from the northwest, and the combined energy jumps to 240 (strong). The forecast says “expect good surf conditions.” That’s the best we’ve got in the whole window. The waves will be a bit of a handful for beginners at that size, but for the intermediate crew, it’s game on. Just remember that with a 7-second period, it’s a short-period wind swell, so it’ll be a bit crumbly and won’t have that groundswell push. It’ll be a bit of a close-out at a beachy setup like Flies, but with the wind clean, you’ll find some shoulders.

Saturday morning, August 8th, is a letdown after that. It drops back to 3 ft from the south, with clean conditions but only 87 (weak) energy. It’s just ordinary again.

So, bottom line: don’t get your hopes up for the first week. The best bet is that Friday, August 7th, morning session. It’s the only time the swell, wind, and energy all come together to give us something proper. Be there or be square.

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.
