The Lowdown
Alright, Rusty here again. Let's cut to the chase for Rat Beach. Over the next 16 days, there's simply no good surf. The swell is tiny, the wind is mostly wrong, and the few clean moments have zero power.
Sunday 30 August kicks off with a tiny 0.7m west swell, but it's a short 7-second period and the wind is onshore at 20 km/h, making it a choppy mess. The water is a steamy 73°, which is 8° warmer than normal – very unusual.
The next few days are a repeat. Monday 1 September and Tuesday 2 September have swell under 0.7m. There are a few clean windows with light winds, but the wave energy is just weak. Even Wednesday 3 September morning, when conditions are described as "surfable," it's still only 0.4m.
The first week is a total loss. The only day with an offshore wind is Friday 4 September morning, but the swell is only 0.7m. The wave energy is almost always under 100, which is weak.
Into the second week, from 7 September, we get some longer period swells from the southwest, with periods reaching 16-18 seconds, but the heights stay tiny, between 0.3m and 0.9m. The energy does climb into the triple digits on a few days, like 266 on the morning of 10 September, but it's all on a 20 km/h cross-onshore wind, making it choppy and useless.
On 14 September, there's a clean offshore breeze, but the swell is a pathetic 0.3m with a 17-second period. It's "surfable but very ordinary."
So, what's a surfer to do? The wind is consistent enough through the afternoons that a kite surfer might have a bit of fun on the small, choppy waves. But for a paddle surfer, there's nothing. It's a dry spell, plain and simple. Forecasts can change, so don't give up hope entirely.
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.
