The Lowdown
Alright, Rusty here, let’s have a look at what’s on the menu for Flies.
Honestly, mate, it’s a pretty lean stretch ahead. There’s a long wait for anything decent, and even then it’s not going to set the world on fire. The first proper chance to get wet is on Friday morning, the 31st of July, but don’t expect much.
Friday morning, the 31st of July, we finally get a bit of a window. The wind is light and offshore from the NW, which is a major positive. The swell is tiny at 3ft from the SSE, with a period of 9 seconds. The combined energy is weak (101). Conditions are clean, but it’s pretty ordinary. This is more of a longboard or foiling session.
The rest of the forecast is a real struggle. Saturday the 1st of August through to the 7th of August is a write-off. The wind is mostly cross-onshore or onshore, and the swell either drops to nothing or gets chopped to pieces. A lot of poor surf conditions in there.
We get a bit more energy in the second week, but with it comes more wind issues. There’s a pulse of 5ft SSE swell showing up on Sunday the 9th of August, with a period of 12 seconds, giving moderate combined energy (567). The wind is a cross-shore, making things messy. The swell direction from the SSE is okay for this spot, but the lack of clean wind ruins it.
The best but still uncertain option comes on Wednesday the 12th of August. We’ve got a solid 6ft to 6ft SSE swell, with a 12-second period. The combined energy is strong (1019). The problem? The wind is a cross-onshore, blowing at 12 to 16 mph from the E. This will be a lumpy, choppy mess. It’s not for beginners, and honestly, it’s more likely to appeal to the kite crew than a paddle surfer. The size is there, but the quality is not.
The water temperature is about average for the time of year, so no surprises there.
Bottom line: don’t hold your breath. The only real standout is Friday morning, the 31st of July, for a clean, tiny session. The rest is a battle with the wind. It’s a tough run for this spot.
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.
