The Lowdown
Alright folks, Rusty here with a look at what's coming our way for the next couple of weeks at Deadman's.
Right now, we're looking at a pretty flat and choppy stretch, so don't rush down there just yet. The week kicks off with onshore winds and messy surf, not worth your time. Things start to turn around on Monday, September 7th. We've got a small, glassy morning with 3ft swell from the WNW. It's not going to be a world-beater, but it'll be clean and rideable. The energy is weak (92), but the clean conditions will be a welcome change.
The real standout for this forecast period lands on Saturday, September 12th. The morning session is the pick. We'll see a solid 10ft swell from the NW, with light cross-shore winds. That's a lot of water moving – the combined energy is a whopping 2334, so this is serious, powerful stuff. At that size, Deadman's is strictly for advanced surfers only. It will be a challenge, but for the crew with the skills, it'll be the session of the period.
Before that big swell arrives, there are a few other windows to keep an eye on. Tuesday the 8th and Wednesday the 9th both have glassy mornings with a tiny 2-2ft swell from the SW. The energy is moderate (163 and 204), and the period is very long (14-19 seconds), which can make for some beautifully shaped lines at this break. Don't expect much size, but for a log or a fun shape, it'll be clean and playful. Thursday the 10th and Friday the 11th have a bit more size (2-3ft) but with less favorable winds in the afternoons. The mornings are marginal but might be worth a look if you're keen.
After the big Saturday swell, the surf settles down again. The following Friday morning, September 18th, looks promising with a glassy 2-2ft, long-period SW swell and "expect good surf conditions" noted. The energy is moderate (330) and it should be a clean, fun morning.
For the rest of the second week, it's mostly small, with onshore winds in the afternoons. The 17th has a clean, cross-offshore morning with a 2-2ft SW swell (219 energy), which is a decent option. Otherwise, the pattern is small and choppy, so pick your windows carefully.

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.
