The Lowdown

Alright, let’s cut to it. The first solid window of surf kicks off right now. We’ve got a run starting Sunday the 9th that’s worth getting wet for.

The first couple of days, we’re looking at a consistent west-northwest swell. Not massive, but there’s decent energy. The combined energy is around 792 on Sunday afternoon, building to a healthier 1232 by Monday morning. That’s moderate wave energy, and it means the reef is getting some proper push. We’re talking chest to head-high, around 7ft to 7ft. The period is short, 8 to 9 seconds, so it’s a windswell – a touch lumpy – but the cross-off wind Sunday afternoon should keep it clean. Monday and Tuesday are more cross-shore, making for a more textured wave.

Now, Wednesday the 12th is where things start to shift. The swell is still pushing 7ft in the morning, similar short period, but the real turn is Wednesday afternoon. The wind swings cross-off, and the waves clean up nicely. The energy is still moderate, but the quality jumps. Then Thursday the 13th is the clear winner of this first push. We get a glassy morning with swell from the northwest at 5ft. The period stretches to 9 seconds, giving it some much-needed shape. The wind is a mere 5 km/h from the WSW – absolutely glass. That’s gonna be clean, rippable surf. Water temp is spot on for the season at 57°F, no real anomaly. That’s the pick of the first week. Deadman’s is gonna be firing.

Then things get messy. The swell drops and swings to the south-southwest. Energy numbers are still there, but the period goes long – 15 to 19 seconds. That’s a problem. Long period in a beach break closes out, but this is a reef, so it might be okay. The problem is the size. Under 3ft, it’s just not doing anything. Wind is mostly onshore or cross-onshore, which doesn’t help. From the 14th to the 17th, it’s pretty much a wash.

We hit a real lull for the middle of the window. From the 17th through the 20th, it’s bleak. Swell is tiny, maybe 3ft to 3ft, and the wind is up, particularly the 18th and 19th afternoons with moderate breezes from the northwest. It’s poor surf. If you’re keen, you might find a sloppy reform, but it’s not worth the hassle. That’s a solid few days of nothing.

But the back half of the window starts to show some life. Friday the 21st is interesting. It’s glassy, light WSW wind, and the swell comes back from the northwest, around 5ft by the afternoon. The period is short again, 6 seconds, so it won’t be epic, but clean and fun. Energy is still low, but the clean conditions save it.

The real hidden gem is Sunday the 23rd. The morning looks perfect – glassy, and the swell is back up to 5ft from the northwest with a slightly better 7-second period. Moderate energy, prime conditions. It’s a long-range call, so a bit of caution, but that Sunday morning has the potential to be the cleanest, most consistent surf of the second week. The afternoon gets a bit cross, so hit it early.

So, to wrap it up: get on Thursday the 13th morning for the best of the first week. Suffer through the flat spell, and circle Sunday the 23rd morning on the calendar. That’s the standout of the back half.

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.
