The Lowdown

Alright folks, Rusty here. Let’s have a look at the outlook for Rat Beach. I gotta be straight with you – this forecast is a tough one. We’re looking at a 16-day window, and there’s a big, long gap at the start with nothing worth paddling out for. The first real whisper of anything surfable doesn’t appear until the 2nd of August, and even then, it’s pretty ordinary.

The water at Rat Beach is running about 72°, which is much warmer than normal for this time of year – a proper anomaly of 4° warmer. That’s very unusual, so you won’t need a thick wetsuit, that’s for sure.

From the 22nd of July right through to the morning of the 2nd of August, it’s a total write-off. The swell is tiny, the wind is mostly cross or onshore, and the wave energy is weak (values between 5 and 88). There’s nothing to get excited about. The only slight glimmer is a few mornings with offshore winds, like Friday the 24th and Sunday the 26th, but the swell is so small (2ft - 2ft) and short period (6-7 seconds) that it’s barely a ripple.

The first sign of life comes on the morning of Sunday, the 2nd of August. We get a clean, light offshore breeze with a small 3ft west swell. The combined energy is still low (81), and the period is short (6 seconds), so it’s surfable but very ordinary. The morning of Monday, the 3rd of August is a similar story – a bit more energy (111) on a 3ft west swell, but again, nothing special. The best chance for a wave might be Tuesday morning, the 4th of August, with glassy conditions, a 2ft west swell, and a bit more energy (78). Still, for a reef break like Rat Beach, you’re hoping for more.

The standout? If I had to pick one, it’s the morning of Wednesday, the 5th of August. We’ve got a light offshore wind, a 2ft swell from the southwest, but here’s the interesting part – the period jumps to 14 seconds, and the energy is moderate at 124. That’s a proper groundswell pulse. For a reef, that long period (over 11 seconds) means better shaped waves and more push, even if the height is small. It’s clean as a whistle, but it’s also inconsistent. Crowds are sometimes a problem here, so if you’re out there on that Wednesday, you might have it to yourself for a bit, then a few others.

Overall, it’s a bleak run. Don’t get your hopes up for the first week and a half. The second week has a few windows, but it’s a struggle. Forecasts can change, so keep an eye on it, but for now, I’d be doing something else.

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.
