The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin' at Deadman's.
First up, the water temp is sitting at 62°F, which is a solid 4°F warmer than what we usually see this time of year. That’s a nice little bonus for the skin.
Right now, we’re in a bit of a flat spell. There’s nothing really worth paddling out for over the next few days. The wind is mostly cross or cross-on and the swell is tiny and weak. Thursday the 3rd is a write-off with a messy 4ft from the west and a moderate cross breeze. Friday the 4th through to Tuesday the 8th is pretty much the same story – small, weak, and messy. The combined energy is all over the place, but the wave quality is poor.
We’ve got a gap of a few days with no real recommendations until things start to look a little more promising. Wednesday the 9th of September shows a little pulse of 2ft to 2ft from the southwest with a very long period of 16 seconds. The wind goes glassy, so the surface will be clean. The energy is picking up a bit (168 to 229), but it’s still very marginal. This is more of a look-see session than a standout.
Now, if you’re patient, the standout window is shaping up for the following week. Thursday the 10th of September morning is a real highlight. The swell is 2ft from the southwest, period is a very long 17 seconds, and the wind is a light cross-off from the east-northeast. The wave comment says "expect good surf conditions," and the energy is moderate (292). That’s a clean, lined-up setup for a point or reef, but Deadman's is a beach and reef break, so that long period will hold up well there. The morning looks blessed.
The other standout is Monday the 14th of September morning. Swell is 5ft from the west-northwest with a 9-second period, and it’s a glassy morning. The energy is solid (352) and the wave comment is "expect good surf conditions." This is a bigger, more powerful wave than the 10th, so it’s better for more experienced surfers. The 5ft is a nice size, but it’s not too big for advanced paddlers.
Looking further out, Thursday the 17th of September morning is also a glassy one with a 3ft west swell with a 12-second period and strong energy (453). But we’re getting into the second week now, so take that with a pinch of salt – it’s promising but less certain.
Overall, the best of the best are the morning of Thursday the 10th of September for the clean, long-period lines, and the morning of Monday the 14th of September for a bit more grunt on a glassy surface. The rest of the time, it’s mostly a waiting game or a chance to check the cams.
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.
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.
