The Lowdown
Alright folks, Rusty here. Let’s be straight with you – we’re looking at a pretty flat and uninspiring run at Rat Beach for the next couple of weeks. There’s no surf worth getting excited about for a solid stretch, so don’t bother paddling out unless you're after a float.
We’re starting off Monday the 10th with no real surf to speak of. Tiny 0.7ft swell with a period of just 4 seconds and absolutely no energy behind it (combined energy of all swells directed here is 1). The water is 71°F with a temperature anomaly of 6°F above normal, meaning it’s much warmer than normal for this time of year – feels like summer. But the waves are a no-go. This flat spell stretches for days. Tuesday the 11th through to Saturday the 15th is a total write-off – you might see a tiny bump up to 1.0ft to 2ft on Wednesday morning (12th) with moderate wave energy around 170, but it’s messy, the wind is cross to cross-onshore, and it’s just not surf. Sunday the 16th morning teases a bit – we get a 3ft south-west swell with a solid 16-second period, and combined energy of 361, which is moderate energy. But the wind is light cross-shore, so it’s only a marginal option. Rat Beach is a reef break and inconsistent as it is, so when it’s this small and messy, it’s barely worth a look.
The standout for the whole outlook would be Thursday the 20th morning. We get a 3ft swell from the west, with a short period around 6 seconds, but the wind is offshore and light from the SSE at 9 mph. That’s clean. Combined energy is moderate (119). It’s surfable but ordinary – not a classic session, but probably the best we’ve got. The south-east offshore wind will make it glassy. Expect cross-off conditions and clean faces. Friday the 21st morning is similar – 3ft from the west, light SSW cross-off wind, combined energy at 114 – again, clean and rideable but not a standout.
After that, it drops off again. The last few days of the outlook – after the 21st – we’re back to tiny 0.9ft to 1ft swell, almost no energy, and mostly cross-on or onshore wind. It’s a total dud. If you were hoping for a big swell, it’s just not here. For the 16-day run, you’ve basically got one or two mornings that are worth a casual paddle. This is not a stretch for beginners – the swell never gets over 5ft anyway, so it’s so small that anyone could wade out. Honestly, with the wind and the tiny size, it looks more interesting for a kite surfer than a paddle surfer most days.
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.
