The Lowdown
Gutted, folks. I’ve been staring at the charts for the next two and a bit weeks and, honestly, it’s a tough one. We’ve got a real dry spell on our hands for the most part. The only spot showing any life is Rat Beach, but it’s a reef setup that’s inconsistent at the best of times, and the forecast just isn’t giving us much to work with. The water is sitting at 72°, which is a massive 7° warmer than normal for this time of year – that’s a real anomaly, you’d be swimming in a bathtub out there.
The first week is essentially a write-off. The swell is tiny and the winds are mostly cross or onshore, which just chops up an already marginal situation. There’s a hint of cleaner conditions on the morning of Sunday the 9th, but with a wave height of only 1ft and a weak energy reading (26), it’s barely a ripple. Nothing to get out of bed for.
Things don’t really improve. We get a slight bump in energy mid-week, with Tuesday the 11th and Wednesday the 12th showing some surfable waves in the mornings. The swell direction is from the southwest, which is okay, but the wave heights are still only 1ft to 2ft. The combined energy on Tuesday morning is 85, which is weak, and even the afternoon reading of 158 is nothing special. The period is a long 18 seconds, which is proper groundswell, but at this size, it’s just not doing anything. It’s the kind of swell that looks pretty on the buoy chart but doesn’t translate to a wave you can actually ride.
The following week, the second week, is more of the same. The morning of Monday the 17th is clean with a light cross-offshore breeze, but the swell is still tiny at 2ft and the energy is a weak 33. There’s a slightly more interesting morning on Tuesday the 18th, with a moderate southeast offshore wind and the swell jumping up to 3ft, but the period drops to a poor 6 seconds. That’s just short-period windswell, and it’s going to be weak and crumbly. The energy reading of 75 confirms it’s all a bit lackluster.
Honestly, there’s not a single standout day here. The only thing even close to a recommendation is the morning of Tuesday the 18th, when that offshore wind will at least make it look pretty, but the wave quality is going to be poor. It’s more of a “have a look if you’re desperate” sort of deal. For the most part, this setup looks more interesting for the kite surfers than us paddle surfers, with the onshore winds and marginal swell. The long gaps of nothing are the real story. We’ve got a solid ten days of nothing before that brief, weak pulse, and then it fades back out again. It’s a bleak outlook, but it tends not to stay poor for long around here. Forecasts can change, so I’ll keep an eye on it.

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.
