The Lowdown
Alright folks, Rusty here, breaking it down in feet and miles per hour.
Honestly, the next two weeks at Deadman’s start off rough. The first ten days are mostly a bust. There’s some small swell, waist to chest-high at best, but the wind is a constant problem. Most of the time it’s blowing cross or cross-onshore, from the west or southwest, turning the ocean into a choppy mess. The combined wave energy ranges from weak to moderate. There’s a marginal morning on Thursday the 10th of September with a cross-shore breeze, but it’s nothing to get excited about. The weekend, Friday the 12th and Saturday the 13th, gets worse with stronger winds, and waves reaching 7ft. That combination is blown out and messy. I wouldn’t be surprised to see kite surfers having more fun than paddle surfers that weekend.
But hold onto your boards, because there’s one real standout. Monday morning, the 14th of September, it goes glassy. The swell is a clean 6ft from the WNW, and the combined energy is strong at 892. The wind is calm, the sky is clear, and the forecast calls for very good surf. This is the session to aim for. The break is fairly exposed to the NW and the swell period is only 8 seconds, so it won’t have tons of push, but with glassy conditions, it’s going to be miles better than everything else. Deadman’s is for advanced surfers and can get crowded, so you’ll have company. The water temp is about normal for this time of year.
That Monday morning is the high point. By the afternoon, the wind swings onshore and it goes downhill from there. The rest of the week into the 22nd is a desert of small, weak, wind-affected surf. There is some long-period groundswell with 19-second intervals showing up on the 20th and 21st, but it’s only 2 to 3 feet and has a cross-onshore wind, so it’s not doing a thing for this spot.
So here it is: the first week and a half, just skip it. The one and only true standout is Monday the 14th, early. Go get that glassy 6ft WNW swell before it disappears.
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.
