The Lowdown
Alright, Rusty here again, but this time in feet and knots.
Let’s be real – it’s a tough stretch. The first decent surf doesn’t roll in until Sunday, September 20th. That’s a 12-day dry spell of mostly small, choppy, or flat conditions. The combined energy is low for most of that time, sitting under 100 for the early days. Water temp is 73°, a full 7° warmer than normal – that’s a big anomaly, so you’ll be in shorts or a thin top.
The only break in the game is Rat Beach, a reef that’s inconsistent and only fires in a few windows. The standout is Monday morning, September 21st. We’ve got a clean 3ft swell from the SW, with a 17-second period – that’s a long-period groundswell, so it’ll have some grunt, but on a reef-beach setup, it might wall up a bit. The wind is light offshore from the SSE, so the surface will be glassy. Combined energy hits 394, which is solid moderate-to-strong. Crowds are possible, so expect company. Sunday the 20th morning is also good: 2ft from the SW, 19-second period, light offshore from the S, and clean. Energy at 325 – again, solid. Winds are cross-offshore, so the waves will be smooth.
The rest of the 16 days? Thursday the 10th morning has a tiny 2ft W swell, 6-second period, and offshore SE wind, but the energy is only 21 – it’s barely a ripple. That afternoon, the swell jumps to 3ft from the SW with 16-second period and 319 energy, but the wind is cross-shore, so it’s messy. From the 11th through the 19th, it’s small, short-period slop and cross-onshore chop – not worth it. The 22nd and 23rd bring small 2ft SW swells, but the winds are variable and the energy drops off.
So, bottom line: Sunday 20th and Monday 21st mornings are your best shots. The rest is a washout. Forecasts can change, but for now, it’s a waiting game.
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.
