The Lowdown
Alright, grab a coffee and have a listen. I'm not gonna lie to ya, the next week and a half is looking pretty grim for Deadman's. It's a beach and reef setup, advanced level, and it's fairly consistent, but the conditions are just not playing ball. Water temps are sitting at 64°, which is much warmer than normal for this time of year, so at least you won't be freezing your nuts off.
Right now, through the end of August and into the first week of September, it's a write-off. We've got a whole lot of cross and cross-onshore winds, choppy surfaces, and the wave comment basically says "poor surf conditions" every time. The swell energy is all over the place, from weak readings around 41 (moderate energy) up to a strong 870 on the 29th of August, but it's all junk. The wind is just shredding it. There's a long period groundswell from the SW on the 24th of August, with period 18 seconds, but it's only 2 ft and the wind is cross, so it's not doing anything for us.
The only real glimmer of hope comes on Sunday, the 30th of August, in the morning. The wind drops off to glassy, there's a little 3 ft SW swell with a period of 16 seconds, and the combined swell energy is a solid 612. The forecast says "expect good surf conditions". That's your one chance for a clean session, but it's a small window. After that, it's back to the choppy mess.
We then have a long gap of nothing until the 6th of September, another Sunday morning. Again, glassy conditions, 3 ft SW swell with a 15-second period, and energy at 355. It's a similar story, but it's a long way out. The 8th of September looks promising as well, with a clean, cross-off wind from the ENE and a 3 ft SW groundswell with a 19-second period, and energy at 613. That's a good sign, but it's far out.
So, there you have it. Not much to get excited about. If you're desperate, the 30th of August morning is your best bet. Other than that, the forecasts are just a mess. The 6th and 8th of September are worth keeping an eye on, but don't book the day off work yet.

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.
