The Lowdown
Alright, Rusty here, let’s talk about what’s coming up for Deadman’s. Straight up, it’s going to be a frustrating stretch for most of the next 16 days. The wave energy is there at times, but the wind is going to absolutely ruin it for us on the paddle side.
Looking at the whole picture, we’ve got a real problem: a near-constant cross-on or choppy wind for a big chunk of the afternoons and even some mornings. The wave energy will climb into moderate and even strong territory—you’ll see readings like 905 and 1072 (strong to very strong energy), but the quality just isn’t there for clean surfing. The water temp is 65°F, which is about 7°F warmer than normal, so that’s very unusual for this time of year.
The first real chance to get wet? Don’t bother until maybe Sunday morning the 23rd. That morning you’ve got a light cross-off breeze, making conditions clean, with a 4ft swell from the WNW at 8 seconds. It’s surfable, but very ordinary. After that, the wind goes ugly again.
The best on offer, and I mean the only standout, is Friday morning the 28th of August. The swell pushes up to 6ft from the NW with an 8-second period, and more importantly, the wind is a light cross from the SW at just 3 mph. The combined energy is cranking at 905 (strong), and with that light breeze, it’ll be the cleanest waves in the whole forecast. But remember, Deadman’s is an advanced, fairly consistent break, and it gets busy often, so expect company for those good sets.
For the next week, the morning of Wednesday the 3rd of September has a solid 7ft swell from the WNW, but that cross-on morning wind will mess it up. The energy is 1061 (strong), but it’s not going to be pretty.
If you’re a kite surfer, the afternoon winds of 12-16 mph from the W or WSW on days like the 1st and 2nd of September, with 7ft+ swell and that cross-on setup, will be far more interesting than anything we can paddle into. For the rest of us, it’s a waiting game.
Keep your eye on that Friday the 28th. It’s the best shot we’ve got.

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.
