Table - best surf conditions forecast for Flies over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you – this is a tough stretch for the Flies area. We’re looking at the next 16 days and honestly, there’s a big fat gap at the start with no real surf to speak of. The wave energy is just too weak and the wind is all over the shop.
The first chance at anything worth paddling out for doesn’t show up until Wednesday, July 15th. Even then, it’s not a classic. Wednesday morning brings a 5ft swell from the southwest, but the period is a short, weak 6 seconds. The combined energy (278) is moderate, but the wind is a gentle cross-offshore breeze, which will keep the surface clean. It’s a beginner-friendly size, but don’t expect much push.
The real standout, if you can call it that, is on Monday, July 20th. The morning session has a 4ft south swell with a slightly better 8-second period and a combined energy of 235. What makes it the pick of the litter is the light offshore from the north, promising clean, glassy conditions. The water temp is about 70°, basically average for this time of year. Still, it’s only a 4ft swell, so it’s not going to be a world-beater. The afternoon that day gets messy with a cross-onshore wind.
After that, the rest of the window is a washout. There are long gaps of days with nothing on offer – the wind is mostly onshore or cross-shore, the swell drops right off, and the energy is weak (often under 100). Tuesday July 22nd and Wednesday July 23rd are particularly grim. Even the glassy conditions on Saturday July 18th come with a tiny 1ft swell, so there’s nothing to ride.
Given the mostly poor quality and the fact the swell is weak and the wind is often cross or onshore for a beach/jetty setup, this stretch might actually be more interesting for the kite crowd than us paddle surfers. Keep an eye on the charts, but for now, it’s a lot of waiting.
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.
