The Lowdown
G'day, Rusty here. Look, I've got to be straight with you – we're in for a bit of a rough patch at Deadman's over the next sixteen days. It's a beach and reef setup that can fire when the stars align, but for the most part, this forecast is a tale of waiting for the right moment. The water is sitting at 63°, which is much warmer than normal for this time of year; feels like a tropical bath.
The first real glimmer of hope doesn't come until Thursday morning, the 3rd of September. There's a clean 2ft swell pushing in from the SW with a long period of 19 seconds – that's proper groundswell energy. Combined energy is moderate (321), and with a light breeze keeping it clean, it'll be your best shot for a session. Just remember, that long period stuff can make beach breaks a bit straight, so look for the rip bowls.
Friday morning the 4th of September sees a bump in size to 3ft from the SW, period of 18 seconds, and combined energy jumps to a strong 706. It's clean with a gentle cross-shore, but the comment says "marginal" – tide might be a factor, so pick your bank.
The morning of Wednesday the 9th of September is where it gets interesting. We're looking at 5ft from the WNW, short period at 6 seconds, but the wind is cross-off and clean. Combined energy is moderate (383). That's a fun size, but 5ft is getting up there for beginners. For the experienced crew, it's a goer.
Then the standout window kicks off. Thursday morning the 10th of September is absolute glass, with a 2ft SW swell, period of 17 seconds, and combined energy of 583 – strong. That's a perfect combo for a point break style wave at Deadman's.
Friday morning the 11th of September is also clean, with a cross-off breeze and a 5ft WNW swell, period of 8 seconds, and combined energy of 532. That's a solid, punchy wave for the better surfers.
After that, the next week is a write-off. The swell hangs around but the wind is onshore or cross-on, making things choppy and messy. There's a glassy morning on Monday the 14th of September with 3ft from the WNW, but the comment says "very ordinary" – it's barely surfable.
So, the real highlights are Thursday the 10th and Friday the 11th of September. If you can wait, those mornings are the ones to circle. The rest of the run is a bit of a stale sandwich, but that's the way it goes sometimes.
Rusty, signing off.

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