The Lowdown
Alright, Rusty here. Let's have a look at what's shaking for your local stretch.
Honestly, mate, the next couple of weeks are a bit of a mixed bag. We've got some solid energy rolling in at times, but the wind is going to be the main character, and not always in a good way. The open window for some clean ones is pretty narrow, so you've gotta be picky.
The first real chance to get wet comes on Sunday, August 30th. The morning is looking like the best bet for the entire outlook period. Deadman's will see a clean 3 ft swell pushing in from the southwest, and with a light 6 mph SSW breeze, it’ll be cross-offshore. That's a recipe for some smooth, lined-up walls. The swell period is a long 16 seconds, so there's some proper groundswell energy in the water – you'll feel that power, with combined energy reading a solid 675. That long period might make it a bit fat and straight on the bank, but for a beach and reef setup, if you pick your peak, it’ll be fun.
After that, it gets frustrating. From Monday, August 31st through to September 5th, the wind goes onshore and the surf quality drops right off. There’s still size around – up to 4 ft on Friday the 4th from the WNW with 769 moderate energy – but it’s all blown out and choppy. Not worth paddling out for.
Sunday, September 6th morning offers a little glimmer. It’s tiny, only 3 ft, but the wind drops to nothing. Deadman's will be glassy. It's surfable, but very ordinary. If you just need to get wet, you could.
The same story repeats on Tuesday, September 8th and Wednesday, September 9th mornings – small, glassy conditions thanks to light southeast and calm winds. Swell is a marginal 2 ft to 3 ft. It’s better than nothing, but you're not going to be telling stories about it.
If I had to call it, Sunday morning, August 30th is the standout. It's the only time in the next two weeks where you get a decent-sized, long-period southwest swell and clean, offshore-friendly wind all at once. Get on it while you can.
Stay salty.
Rusty.

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.
