The Lowdown
Alright folks, Rusty here. Let’s be real about Rat Beach – this 16-day window is a tough one. We’re looking at a long stretch of nearly nothing, so don’t get your hopes up. The first few days are a total write-off, with flat spells and tiny, choppy slop. The water’s sitting at a very unusual 73°F, which is much warmer than normal for this time of year, but that’s about the only good thing going on.
We’ve got a big gap of no surfable waves until the morning of Thursday, September 10th. That morning, a slight pulse of 3ft swell from the SW comes through with a decent 10-second period and clean offshore SE wind at 12 mph. The combined energy is moderate at 145. It’s rideable, but it’s the only highlight in a sea of mediocrity. That afternoon, it gets a bit bigger to 3ft (SW, 11s) with a combined energy of 233, but the wind swings cross-shore, so it’s not as clean.
The next few days drift back into poor conditions. By Friday, September 11th, the morning shows some rain showers and a 3ft SW swell, but the wind is cross-offshore, keeping it clean. However, the energy is weak at 75. The afternoon gets a bigger 2ft swell with a very long period of 15 seconds, pushing the energy to a strong 303, but it’s blown out by cross-onshore wind.
The only other slightly promising window is Friday, September 18th, and Saturday, September 19th. Friday morning sees a 2ft SW swell with a very long 20-second period, giving a combined energy of 362 (strong). The wind is light cross-onshore, so it’s not perfect. Saturday morning is similar, with a 2ft SW swell, 18-second period, energy of 281, and the lightest breeze. These are the best bets for a wave, but with such long periods and a beach-reef setup, it might break a bit too straight. Still, for a quiet session, it’s your best shot.
Overall, this is a poor run. The surf is inconsistent, and the spot is rarely breaking well. Blank runs like this are more normal for this area, so don’t lose faith. Forecasts can change.
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.
