The Lowdown
G’day, I’m Rusty, and I’ve been poring over the charts for you. Let’s get straight into it.
The next 16 days are looking pretty grim for Rat Beach. There’s barely a pulse in the water, and most of the time the conditions are just ordinary or worse. The wind is often cross or cross-onshore, and the swell is tiny. You’ll be waiting a long time for anything worthwhile — in fact, there’s a big gap of flatness or poor surf from the start right through to the end of the first week. The second week isn’t much better, but there are a couple of mornings that might just be worth a look if you’re desperate.
The standout option, if you can call it that, is Saturday 15th August morning. The swell is 2 ft from the southwest with a period of 17 seconds — that’s a long-period groundswell, so it’ll have some push despite the size. The combined energy is moderate at 223, and the wind is light and cross-off from the south, keeping it clean. Water temperature is about average for this time of year, so no surprises there. But remember, Rat Beach is a reef break that’s inconsistent and rarely breaks, so don’t get your hopes up too high. The crowds are sometimes there, but on a day like this, it might be quiet.
Another morning to keep an eye on is Friday 14th August. The swell is 2 ft from the southwest, period 14 seconds, with cross-off winds from the south. The combined energy is moderate at 116, and the surf is clean. It’s still very ordinary, but it’s one of the better sessions on offer.
Outside of those two mornings, the rest of the period is a write-off. The swell is tiny, the wind is messy, and the combined energy is weak. For example, from Wednesday 12th August afternoon, the wind swings to 16 mph from the west, making it cross-on and choppy with only 2 ft of poor swell.
Overall, this is a pretty bleak run. Rat Beach is a reef that doesn’t break often, so a blank stretch like this isn’t unusual. Keep an eye on the forecasts, but for now, I’d say leave the board at home.

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.
