The Lowdown
Alright folks, Rusty here. Let’s chew the fat on what’s going down at Rat Beach.
Right off the bat, I gotta be honest – it’s looking bleak for the next week. The swell is tiny and the conditions are just average. We’ve got a real flat spell from now until the end of July. The mornings are clean, but with waves barely hitting 2ft and a weak, short-period windswell, there’s just no grunt to get a proper ride. The combined wave energy is weak, with readings mostly in the teens and twenties. It’s a real downer.
Things finally show a little life on the 3rd of August. A new, longer-period swell from the southwest starts to trickle in, with a period of 16 seconds, but the height is still tiny – just 1ft. The energy is still weak at 73, but at least it’s a groundswell. The wind is light and cross-offshore, so the surface will be glassy. It’s "surfable waves but very ordinary" – you’ll be scratching for a ride, but it’s not a total washout.
This pattern of small, long-period SW groundswell continues through the 4th and 5th of August. It’s still tiny, with wave heights around 1ft to 2ft and periods of 14-15 seconds. The energy is still weak, topping out at 77. The mornings are clean with light cross-offshore winds, but the afternoons get chopped up by a cross-onshore breeze. Honestly, it’s still a longboard or a big foiler kind of session.
The biggest energy we see comes right at the end of the forecast window, on the 10th and 11th of August. The combined energy jumps to 144 and 150 in the afternoons, which is moderate. But look closer – the swell is tiny (0.3ft to 1ft) and the wind is howling onshore at 12-15 mph. That’s a recipe for a messy, blown-out surface. The long period from the southwest (18-19 seconds) would be nice if there was any size, but there isn’t. It’s a total no-go for paddle surfing.
So, what’s the verdict? The water is a very unusual 72°F, which is nearly 7°F warmer than normal for this time of year – a real treat if you’re just having a dip. But for the actual surf, there’s no standout option in this 16-day window. The only faint glimmer of something surfable is the mornings of August 3rd, 4th, 5th, and 7th, but the waves are barely breaking. If you’ve got a longboard and are desperate for a glide, that’s your window. Otherwise, it’s a long dry spell.
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.
