The Lowdown

Alright, Rusty here. Let's look at what's cookin' at Rat Beach. Honestly, it's a pretty flat and quiet stretch ahead. This is a reef break that's inconsistent and a beginner-friendly wave, so we're not expecting any bombs. Water temp is about 72°F, which feels a lot warmer than usual for this time of year, so that's a silver lining.

Right now, Tuesday the 11th, we're looking at 1ft to 2ft of SW swell with a very long 18-second period, but the wind is all over the place, cross and cross-on, making it choppy and messy. The combined energy is weak (85) on Tuesday morning, so it's a pass.

We get a little cleaner on Thursday morning, the 13th. The wind goes light and cross-off, so it's clean, but the swell is still a tiny 2ft from the SW with a 16-second period. The energy is weak (130). It's "surfable but very ordinary." That's the best we can say. Same story on Friday morning, the 14th.

There's a long dry spell until the morning of Wednesday the 19th. That morning, the wind goes glassy, and we get a tiny 3ft W swell with a 7-second period. The energy is still weak (83). It's clean, but it's barely a ripple.

The most interesting window is the morning of Thursday the 20th. The swell bumps up to 4ft of W swell with a 7-second period, and the combined energy hits moderate (293). The wind is light cross-shore, so it's semi-clean. The report calls it "marginal," but for a spot that's inconsistent, this is the best push we'll see.

Then on Friday morning, the 21st, we get a clean 4ft W swell with offshore winds from the SE at 9 mph. The energy is moderate (204). This is the standout. The offshore wind will groom the lines, making it the cleanest surf of the whole run. It's not big, but it's the one to aim for.

After that, it fades back into tiny, weak SW groundswells for the rest of the month. For a spot that rarely breaks, this is a pretty bleak run. If you're itching, save your energy for that Friday the 21st morning.

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.
