The Lowdown

Alright, surf’s up… or at least, it’s trying to be. We’ve got a pretty quiet stretch ahead for Deadman’s. It’s an inconsistent spot, so we’re not looking at a lot of consistent action, but there are a few windows where it’ll clean up and offer some fun waves. Let’s break it down day by day.

The week kicks off with small, weak surf. Tuesday the 18th and Wednesday the 19th are pretty much a washout, with knee-high slop and a cross-shore breeze messing up the surface. Water temps are sitting at 57°F, which is about normal for this time of year, so a decent 4/3 will do.

Thursday afternoon the 20th is where things start to look a little more interesting. The wind drops to glassy and we get a small 3ft SSW swell at 14 seconds. The combined energy is weak (565), but that clean surface will make it feel better than it looks. It’s a marginal call, but your best bet in the early stretch.

Friday the 21st is a step back—small, lumpy, and not worth the paddle. Saturday morning the 22nd is poor too, but Saturday afternoon the wind goes dead calm and we get a jump in size: 4ft of short-period NW windswell. It’s a bit crumbly but clean, and the energy picks up a touch. Sunday the 23rd is similar, with 4-4ft of NW windswell and glassy conditions. Both are rideable and fun on a longboard.

Monday the 24th has a small SW groundswell at 18 seconds. The period is long, and for a reef like Deadman’s, that can be a plus—it’ll have some push, but only 2ft of it, so it’s small. Still, glassy conditions make it a clean, cruisy option.

The next real standout is Tuesday the 25th. The morning is bumpy, but the afternoon turns glassy with a 2ft SW swell at 16 seconds. The energy is moderate (592) and it should be clean and lined-up. Wednesday the 26th morning is blown out by a fresh cross-shore, but the afternoon is clean, with a new 6ft NW windswell. That’s a step up in size, but the period is short (6 seconds), so it’ll be fat and crumbly, plus the wind is cross-off. Not the best shape.

Thursday the 27th is similar, with 5-6ft of short-period NW windswell and a moderate cross-shore breeze. It’s not great.

Then we get a couple of quieter days—Friday the 28th and Saturday the 29th are back to small, marginal SW groundswell with cross-shore winds. Nothing special.

Sunday the 30th looks promising again. The morning is glassy with 3ft of SSW swell at 16 seconds. The energy is moderate (611), and it should be clean and fun. This is another solid pick.

Then we hit a bit of a junky period. Monday the 31st sees a pulse of NW windswell, 5-6ft, but it’s cross-onshore and short-period, so it’ll be lumpy and stormy. That persists into Tuesday the 1st of September, with similar conditions and a cross-shore wind. Not great for the paddle, but if you’re into a bit of a beat-down, it’s there.

Finally, Wednesday the 2nd is a mixed bag. The morning is blown out, but the afternoon brings a bigger 6ft NW windswell with a cross-off breeze. It’s the biggest swell of the period, but the period is only 7 seconds, and it’s over 5ft, so it’s probably too much for beginners and better for the experienced crew out at Deadman’s. The energy is strong (755), but the quality is questionable.

So, overall, it’s a stretch of small windows and marginal surf. The standouts are Thursday the 20th afternoon, and Sunday the 30th morning. Both offer clean, glassy conditions with some manageable swell. The rest of the time, you’re chasing the calm patches. It’s not a classic run, but there are waves to be had if you’re patient.

Rusty out.

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.
