The Lowdown
Righto, let’s have a look at what’s on the cards. For the next 16 days, we’re talkin’ about Rat Beach. It’s a reef setup, inconsistent, and when it does fire it needs a specific NW swell direction. The water temp is about average for this time of year, so no major surprises there.
The forecast kicks off with a real dud. Monday the 7th we’ve got tiny wind ripples, cross-on breezes, and no hope—combined energy barely reaching double digits (4 to 11). Tuesday the 8th and Wednesday the 9th stay in that flat, messy zone with a bit more period but no power. Thursday the 10th sees a light offshore in the morning with a 2ft windswell from the west (6 seconds), but it’s skinny. The afternoon picks up a 3ft south-west groundswell with a 16 second period, energy jumping to 319, but it’s cross-shore and only rated marginal.
Friday the 11th has a gentle offshore in the morning, small again at 2ft, period 6 seconds—clean but weak. Saturday the 12th offers a brief window: morning offshore wind, 2ft at 14 seconds from the south-west, energy at 177. It’s surfable but ordinary. Sunday the 13th repeats that pattern with a moderate offshore, 3ft at 7 seconds. Nothing to write home about.
The whole second week is a grind of tiny swells and cross-off winds, some clean moments but never enough push. Energy stays under 200 most days, with a few spikes. The real standout appears right at the end. On Friday the 18th, we get a strong jump: morning clean, 2ft south-west swell with a 19-second period, combined energy a solid 421. That’s a proper long-period groundswell bringing some punch. Light offshore breeze, clean conditions—best session of the whole run right there. The reef should handle that long period well.
But then Saturday the 19th morning is a wild card. The swell prediction jumps to 5ft from the west, 7-second period, energy 508. That’s a lot of water moving for this break, and the note says it’s too big for Rat Beach. For the experts only, and even then it might be a wash. The wind is light offshore though, so if you’re brave… but honestly, the Friday morning is the one true standout. Saturday morning is more of a spectacle.
So overall, you’ve got a long flat stretch from the 7th right through to the 17th, then a taste of something decent on the morning of Friday the 18th. After that, the 19th morning is a beast but risky. The rest of the second week fades back to small and cross-on. If you’re keen, pencil in that Friday 18th morning for the cleanest, most energetic surf—just don’t expect much before then.

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.
