The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Rat Beach.
Honestly, it’s a pretty flat and quiet stretch ahead. The first week or so is basically a write-off for any kind of decent paddle session. We’ve got a long gap of nothing doing. The first real chance to even think about getting wet doesn’t show up until Thursday the 10th of September, and even then it’s pretty ordinary. The water is a toasty 72°, which is much warmer than normal for this time of year, so that’s one thing goin’ for ya.
The real standout, if you can call it that, is the morning of Saturday the 19th of September. We’ve got a solid 5ft swell rollin’ in from the west, with a combined energy reading of 462 (moderate wave energy). That’s the biggest push of the whole period. Problem is, that’s getting a bit meaty for this setup, and the forecast says it might actually be too big for Rat Beach. The wind is light and cross-shore, so conditions would be not too choppy, but you’d need to be an experienced hand to handle that size here. The period is a short 7 seconds, so it’s windswell, not a clean groundswell.
The next best options are the 17th of September, Thursday morning and afternoon. The afternoon sees a 4ft swell from the west, with a combined energy of 153 (moderate). The wind is light and cross-offshore, so the surf will be clean. It’s not gonna blow your mind, but it’s the most consistent-looking day before that big Saturday.
The 10th of September afternoon has a bit of size at 3ft with a 16-second period, giving it a combined energy of 363 (moderate). That long period suggests good shape, but the wind is cross-shore, so it’ll be a bit chunky.
For the rest of the time, it’s all small, choppy, or just flat. Not much to get excited about, and crowds are a possibility at this spot, so don’t expect to have it to yourself.
Rusty.

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.
