The Lowdown
Alright, this is Rusty. Let’s break down what’s in store for our local waters.
Honestly, the next 16 days are looking pretty bleak for surf. We’ve got a long dry spell through the first week, and even when a bit of energy shows up, the wind is fighting us. The water is running at 69° – that’s a full 8° warmer than usual, which is very unusual. It’s more like a lake than an ocean right now.
From Tuesday, 18 August, right through the end of the month, the surf is tiny. We’re looking at nothing above 4ft, with most days offering barely a bump. The wind is mostly cross-off or light, so the surface is clean, but there’s just no power. The combined wave energy is weak, with values mostly in the double digits – like 110 on Tuesday morning, 72 in the afternoon, and dropping to 51 on Wednesday. It’s a flat spell, plain and simple. On Sunday, 23 August, we get a brief moment of glassy conditions in the morning, but the swell is a pathetic 0.7ft, with period at 9 seconds. That’s not surfable.
Then we roll into the second week. There’s a bit of a pulse on Tuesday, 25 August, with a 6ft swell from the SW, period around 9 seconds. The combined energy jumps to 755 (moderate energy), but it’s mostly a cross-onshore wind from the ESE at 19 mph, making it lumpy and messy. That’s not a day for a standard paddle board. That setup, with fresh wind and a beach break, is more interesting for kite surfing than paddle surfing.
The rest of the week into early September stays small, with the swell dropping back to under 3ft. The wind is a mixed bag, but nothing lines up. Even on 1 September, when we get a 4ft swell from the WSW (period a short 6 seconds) and a combined energy of 104, the wind is cross-shore and bumpy. It’s poor.
The only real standout, if you can call it that, is Tuesday, 25 August morning. The swell is the biggest we’ll see, at 6ft, from the SW, with a period of 9 seconds. The energy is there (755). But that wind is a killer. If you’re desperate, you might find a bank that’s holding, but it’s not going to be pretty. The best call is to wait for the next window.
Stay patient.

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