The Lowdown
Right then, let’s have a look at what’s on offer for the next couple of weeks.
To be honest, it’s a pretty quiet stretch ahead. There’s a big gap of nearly a week before we see anything worth getting excited about. The first few days offer nothing but tiny, weak waves and poor conditions, so you’re best off leaving the board in the shed.
The first real chance to get wet doesn’t come until Friday the 24th of July. Early that morning at Rat Beach, we’ve got a clean little 3 ft swell from the west with a light offshore breeze from the SSE. It’s not going to blow your mind, but it’s surfable. The water temp is about average for this time of year, so no surprises there.
The standout window, and the one to really aim for, is Monday the 27th of July. Rat Beach is looking very promising that morning. We’ve got a clean 3 ft swell from the southwest, with a very long period of 18 seconds. That’s proper groundswell energy, and the combined energy is a strong 578, so there’s some real push behind it. The wind is a slight air from the SSW, meaning it’s glassy and clean. This is the best surf on offer, no question. It’s a reef break, inconsistent, and crowds are possible, so pick your time and be patient. The long period will mean longer lulls between sets, but the waves that come through will have real shape and power.
After that, the surf drops away again. The next week sees mostly small, weak swell with onshore winds, though there are a few clean mornings with small waves on the 28th and the 3rd of August. Nothing that matches the quality of that Monday.
To sum it up: if you’re keen, save your energy for Monday the 27th of July. That’s the one.

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.
