The Lowdown
Alright, this is Rusty. Let’s size up Rat Beach over the next couple of weeks.
Honestly, it’s a tough stretch. Rat Beach is an inconsistent reef that needs everything to line up, and we just aren’t seeing much of that for the next 16 days. The water temp is about 72°, which is much warmer than usual for this time of year – that part is a treat while you wait.
The first few days start August 24th, but the surf is tiny and messy. A 1ft SW groundswell is there, but winds are cross-onshore.
August 25th Tuesday morning offers a slight improvement: 2ft from the SW with a very long period of 16 seconds. Combined wave energy is moderate (183). The wind is cross-off, with light air, making it clean. You could snag a few, but it’s still ordinary. The 16-second period means these lines will bend around the reef a bit – could be fun for a beginner.
Wednesday, August 26th morning is similar. 2ft from the SW, 16-second period, and offshore wind (SSE, 10 mph). Combined energy is 148. Small and clean, surfable if you’re patient.
Then a massive dry gap. From August 28th right through September 5th, it’s flat or junk. Swell and period drop way off, winds are messy onshore. This stretch looks like it’s more for kiteboarding than paddle surfing.
The true standout is way out there – Monday, September 8th morning. A 2ft SW swell with a heavy 19-second period hits. Combined wave energy jumps to 344 (strong). Offshore wind from the SE at 22 mph gives clean faces. That is the best call in this whole window. The very long period groundswell will wrap nicely into the reef – but it’s still only 2ft, so more of a clean, rippable wave than a monster.
September 8th afternoon fades to a clean, small 3ft from the west.
So, the early days around August 25th–26th give you some clean but tiny waves. The only true standout is September 8th morning – offshore, strong energy, clean. The rest of the schedule is desert. It happens here.
Stay patient. 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.
