The Lowdown

Alright, I’m gonna level with you. This is one of those stretches where the ocean just doesn’t want to play ball. Rat Beach is looking pretty quiet for the next couple of weeks, with only a few fleeting moments that might just be worth a paddle.

The water temperature at Rat Beach is sitting at 72°, and that’s a whopping 6° warmer than usual for this time of year. That’s very unusual – you’ll feel like you’re surfing in a bath.

The outlook kicks off on Wednesday the 26th of August, but honestly, don’t bother. Small 2ft swell from the SW with a long 16-second period, but the wind is cross and the energy is a weak 128. The conditions are just poor. Hold out.

Thursday the 27th of August morning is where it gets a tiny bit interesting. We’ve got a tiny 1ft swell from the SW, but look at that wind – a gentle offshore from the SE. The water is clean, and the energy is a low 74, but it’s surfable. It’s not going to blow your mind, but if you’re desperate for a slide, this is the best you’ll see for a while.

Then the window goes pretty quiet. Friday the 28th and Saturday the 29th offer nothing but poor surf with cross and cross-onshore winds. Sunday the 30th of August morning has a bit of a pulse – 3ft from the W, but it’s a short 7-second period, and the wind is cross-off. The energy is weak at 88. It’s clean, but the waves are just ordinary.

Monday the 31st of August through to the 5th of September is a real lull. Most of these days have zero wave energy or tiny, weak swells with poor conditions. There’s a long gap of nothing really worth mentioning.

Now, look ahead to Saturday the 5th of September morning. A tiny 1ft SW swell with a 6-second period, but the wind is light cross-off and it’s clean. The energy is a measly 11, but it’s a window of clean water. And then Sunday the 6th of September morning offers a 2ft W swell with a 5-second period, and a gentle offshore wind from the SE. Clean again, but very weak.

The only other blip comes on Wednesday the 9th of September afternoon. A 2ft SW swell with a 16-second period, and a weak 130 energy. The wind is cross-shore, so it’s a bit messy.

Honestly, there’s no standout session here. The best options are the Thursday morning (27th August) and the Sunday morning (6th September) for the cleanest, most surfable conditions, even if the waves are tiny. For anything else, you’re just looking at flat, choppy, or cross-shore junk. The break is inconsistent, and it’s showing.

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.
