The Lowdown
Alright, so the first surf that’s even worth mentioning is Thursday morning, the 3rd of September. We’ve got a tiny 0.4m swell rolling in from the SW with a period of 15 seconds. That long period (groundswell) gives it a bit of push, and the combined wave energy is moderate at 124. The wind’s a light cross-off – clean. It’s surfable, but only just. Expect small, clean lines. No recommendation for a standout here, it’s just the best of a bad bunch.
We then hit a huge gap. From Thursday afternoon all the way through to Wednesday morning, the 9th of September, there’s nothing worth paddling out for. That’s nearly six days of tiny, choppy, or crossed-up junk.
On Wednesday morning, the 9th, we get a bit of a nudge. A 1.0m swell from the west, period of 6 seconds, with combined energy hitting 115 (moderate). Wind is light and cross-off, so it’ll be clean. Still, that short period means it’s weak and a bit fat. It’s the biggest swell we’ve seen, but it’s not good.
Then another gap. Nothing decent until Friday morning, the 11th of September. This is the closest thing to a highlight in the whole run. We’ve got a 0.6m swell from the SW, period of 16 seconds (very long groundswell), and combined energy of 213 – moderate to strong. The wind is offshore from the SE, light at 15 km/h. That’s clean. The long period will draw out some lines, but at this size and at a beach/reef setup, it might be a bit too straight. It’s the best wave quality on offer, but don’t expect a miracle.
Saturday morning, the 12th of September offers a similar story: 0.6m SW swell, period 14 seconds, energy at 219 (strong). Light cross-off winds keep it clean. Another session for the patient surfer.
Monday morning, the 14th of September shows a 0.5m SW swell with a period of 18 seconds and energy of 157 (moderate). Clean with light cross-off winds. Again, it’s surfable but tiny.
Finally, Thursday afternoon, the 17th of September wraps things up with a 0.4m SW swell, a period of 21 seconds – that’s a *very* long period, giving it some serious push for its size. Combined energy is 223 (strong). But the wind is a fresh cross-onshore at 25 km/h, making it choppy. A real shame.
Bottom line: There are no real standouts here. If you’re desperate, the mornings of the 11th, 12th, and 14th of September offer the cleanest, most energetic little waves. But honestly, for the size, the consistency, and the raw quality, this is a time to be looking at other hobbies. The whole setup looks more interesting for kite surfing than paddle surfing when the wind picks up. Because this is pretty much the only show in town, and it’s a quiet one.

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.
