The Lowdown

Alright folks, Rusty here. Let's talk about what's cookin' at Rat Beach.

Look, I gotta be straight with you – the next two weeks are lookin' pretty bleak. We're staring down a long run of tiny, weak, and messy surf, so if you're itching to paddle out, you'll need to be patient. There's a big gap of flat days to start, and then just a few windows where it gets barely rideable. The only flicker of real hope is a long way off.

The water is sitting at a balmy 73°F, which is *much* warmer than usual for this time of year – nearly 7°F above average. That's pretty wild, and you'll be comfortable in a shorty or even boardies if you can handle the chill.

Right from the get-go, Friday the 4th is a no-go. There's a tiny 2ft W swell with a short 5-second period, and while the morning wind is offshore, the energy is just 12 – it's a total dud. Saturday through the middle of the following week is almost completely flat, with no swell at all. You'd be better off finding something else to do.

We finally get a whisper of life on the morning of Sunday the 13th of September. A 2ft SW groundswell with a 13-second period rolls in, and the wind is light and cross-offshore, making it clean. The energy is moderate at 171, but it's still tiny. After that, we're back to windy, choppy junk for days.

There is one standout, but you have to wait for it. The best on offer is the Saturday morning of the 19th of September. We get a solid 2ft SW groundswell with a very long 18-second period. That long period means proper lines of energy (combined energy of 314), and with a light offshore breeze from the SSE, the place should be glassy and clean. Keep in mind that a long period swell like this can break a bit straight at a beach setup, but clean conditions will help. It's a reef break that's *inconsistent*, so don't expect a wave every minute, and the crowds can show up sometimes, so you'll have some company.

Honestly, for the next two weeks, that Saturday morning is your only real shot at something decent. The rest is a write-off. Don't bother with the afternoon that day – rain and onshore wind will kill it.

Rusty, signing off.

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.
