The Lowdown
G’day, Rusty here. Let’s be straight with you—this stretch is a flat spell for the most part. We’ve got one spot, Rat Beach, and it’s not exactly firing. It’s a reef break, so it needs a bit of push, but it’s been inconsistent, and that’s putting it kindly. For the next week and a half, we’re looking at a whole lot of nothing worth paddling out for. There’s a gap from the start until around the 11th, where we finally see a pulse of energy, but it’s still small.
The first real sign of life comes on the 11th, with the morning session. Swell from the southwest, 2ft, with a long 18-second period. That’s proper groundswell, but it’s breaking straight at this reef, so you might be better off watching than riding. The energy is still weak (75), and it’s clean with light winds, but it’s just not enough to get excited about. The 12th and 13th mornings are similar—2ft, southwest, with 16-17 second periods, still clean but small. The energy picks up a bit (170 at most), but it’s still moderate at best.
Honestly, the only time we see anything near a real wave is on the 20th, Thursday morning. That’s over a week away, so treat it as a promising idea rather than a guarantee. Swell bumps to 3ft, from the west, with a short 7-second period. The energy is moderate (97), and the wind is light, so it’ll be clean. But it’s still a beach-reef setup, and with that short period, it’s going to be a bit soft and crumbly. Not a standout, but maybe the closest thing we’ve got.
For the rest of the window, it’s a lot of sub-2ft dribble with cross-shore winds messing up the afternoons. The mornings are often glassy, but there’s just no swell to work with. If you’re a beginner, the 2-3ft days with clean conditions could be manageable, but a swell over 5ft is out of the question here until the 20th, and that’s still small.
One thing to note: the water temp is about average for this time of year, so no surprises there. But I’d be lying if I said this was a good look. It’s a quiet period, and my advice is to save your energy and check back closer to the 20th. Forecasts change, but right now, it’s a waiting game.
Rusty, out.

Information about the Rat Beach Surf forecast
The above surf forecast table for Rat Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rat Beach can be found by selecting the local surf guide option on the grey menu. Our Rat Beach 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 (Rat Beach) 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 Rat Beach 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.
