The Lowdown

G'day, Rusty here.

Alright mate, lookin' at the next fortnight for Deadman's, it’s a bit of a mixed bag. This is a beach and reef setup that needs the right direction and for the wind to play nice, and for the first week or so, it’s just not happening. We’ve got swell on the table, but the wind is gonna be a dirty cross-onshore from the west most of the time, absolutely chopping it up.

We go from Tuesday the 8th all the way through to Saturday the 12th and there’s nothing worth paddling out for. The wind is all over the shop – cross, cross-on – and the wave quality is just poor. The combined swell energy climbs from a moderate 109 up to a strong 737 on Saturday the 12th, but that’s coming with a fresh cross-onshore and a short, bumpy period of 7 seconds. It’s big enough at 7 ft by Saturday afternoon, but with that wind, it’s a washing machine. Honestly, for a beach-and-reef setup like this with that kind of wind and swell, it looks more like a kiteboarding day than a surfing one.

Then we get a window. Sunday morning the 13th is our first real stand out. The wind goes glassy from the WSW, calm as. Swell is a solid 6 ft with a 7 second period, but the combined energy is still a strong 578. The report says “expect good surf conditions” so it’s a chance. The wind is perfect, so you’ll get clean, peeling lines. Just be aware it’s a touch on the big side for beginners, and it’s a spot that can get crowded often, so get down early.

The afternoon of the 13th and the whole of the 14th, 15th and 16th are back to poor conditions – that westerly wind comes back onshore and ruins the shape. The swell drops away too.

Now, lookin’ into the second week, there’s a couple of promising mornings. Saturday the 19th has a glassy morning with a 2 ft, 18 second period groundswell. The energy is at a moderate 218. That’s a long period, which will give some nice, clean lines at Deadman's, but it’s small. For the real standout though, you want Sunday the 20th. That morning is dead flat calm, totally glassy. Swell is 2 ft from the SW with a 19 second period, giving a combined energy of 413. That’s the sweet spot. Clean, glassy, and some of those groundswell runners will wrap in nicely.

After that, Monday the 21st is back to onshore junk, but then Wednesday the 23rd has another absolute glass-off. The swell is 4 ft from the WNW with a 10 second period. It’s a bit bigger, the energy is a strong 441, and with completely calm winds it’ll be the pick of the whole run.

So to boil it down: if you can make Sunday morning the 13th, grab it. But for the real clean, long-period gems, keep your eye on Sunday the 20th and Wednesday the 23rd. The rest of the time? Leave the board in the car.

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.

Deadman's is 6 km (4 miles) from the city of San Francisco. If you plan a vacation in Marin County, look for hotels and other accommodation in San Francisco. San Francisco has rooms for a wide range of budgets as well as car hire and transport links.
