Alright folks, Rusty here, talking about Back Beach.
Look, I’m not gonna lie to you. The next 16 days are a bit of a mixed bag at Back Beach. We’ve got some serious size coming through, but the wind is gonna be the story for most of it. The water is sitting at 68°, which is pretty much spot on for this time of year, so nothing weird there.
The real standout is Tuesday morning, July 14th. That’s your window. We’ve got a solid 8ft swell from the WSW, with a long 15-second period – that’s proper groundswell. The wind is blowing offshore from the NE at 12 mph, which will keep it glassy. The combined energy is moderate (2479). This is an excellent session for experienced surfers, as the size is pushing into expert territory. It’s a clean, open face waiting for you, but it’s not for the beginners.
The Monday before that, July 13th, is a write-off for paddle surfing. The swell is a massive 10ft with a 17-second period, and the energy is very strong (5468). That’s too big for this break, and even though the wind is favorable, the wave comment tells the story. It’s just too much.
After that Tuesday peak, the wind starts to mess things up. Wednesday the 15th, Thursday the 16th, and Friday the 17th all have some swell, but the wind is either cross-off or cross. The quality drops off. The Friday afternoon session on the 17th is a total dud with a cross-on breeze and a risk of thunderstorms.
From Saturday the 18th through to the end of the outlook, it’s a real struggle. The swell is still there, ranging from 8ft to even 13ft, and the combined energy is very strong (up to 8640). But the wind is consistently cross-on and strong, making it choppy and messy. On the 20th of July, with 28 mph winds, it’s looking more like a kite-surfing spot than a wave to paddle. There are a few mornings on the 25th and 26th that look a little better with lighter winds, but the comments are still marginal at best.
So, to sum it up: if you’re an experienced surfer, clear your schedule for Tuesday morning, July 14th. That’s the one. The rest of the window is a waiting game for the wind to drop. It’s a long stretch of poor conditions, but don’t lose hope – forecasts can change.
Rusty.

Information about the Back Beach Surf forecast
The above surf forecast table for Back Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Back Beach can be found by selecting the local surf guide option on the grey menu. Our Back 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 (Back 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 Back 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.
