The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Deadman's over the next couple of weeks.
Look, I gotta be straight with you. The next week and a half is a bit of a write-off for anything decent. We’ve got swell on the charts, but the wind is just not playing ball, and most of the time it's a choppy, cross-shore mess. The water is a balmy 64° though, which is much warmer than normal for this time of year, so at least you won't be freezing your tail off while you’re sitting there watching it.
The first real glimmer of hope shows up on Tuesday the 11th of August. The morning session is where it's at. We’ll see a clean 4ft swell from the WNW, and the wind is gonna be a light, cross-offshore breeze from the SSW. That’s a proper setup, and the wave energy is moderate (393). It’s not huge, but it'll be clean and the period is a solid 10 seconds, so you’ll get some decent shape. The crowds are a bit of a worry here though, as it’s often packed, so get there early.
The next morning, Wednesday the 12th, is also worth a look. Another clean morning with a gentle cross-offshore breeze and a similar 5ft WNW swell. The energy is moderate (416) and it’ll be clean, so it’s a solid option if you missed Tuesday.
After that, it’s back to the struggle. We get a few mornings with marginal conditions, but the afternoons are always blown out. The second week looks like a bit of a desert, with the wind staying uncooperative and the swell dropping. There’s a little bump in size around the 21st of August, with 5ft WNW swell, but the wind is cross-on, so it’s not going to be pretty.
So, there you have it. The standout is the clean windows on Tuesday and Wednesday mornings next week. That’s your best shot. After that, the outlook is pretty grim, but forecasts can change.
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.
