The Lowdown
Alright, let’s get into it.
Gonna be a frustrating stretch ahead, folks. The whole sixteen-day window is lean, and honestly, when I look at what’s cookin’ at Deadman’s, it’s a whole lot of “meh” and “nope.” We’re talkin’ an advanced-level beach and reef set-up that’s fairly exposed, and the optimum swell direction is from the NW. Crowds? You’ll likely see folks out there often, but that won’t matter much because the surf just isn’t cooperating.
The water temperature is sitting at 62°F – that’s 5°F above normal for this time of year. Yeah, it’s much warmer than usual, so at least it won’t be a shock when you get in, but that’s about the only good news.
The first half of the run is straight-up grim. Wednesday the 5th through Sunday the 9th of August is a solid block of poor surf conditions. Swell is tiny, mostly 1ft to 2ft from the SW, short period, and the wind is cross-shore and messy. Sunday the 9th morning bumps up to 6ft from the WNW, but it’s still cross-shore, and the energy is moderate (528). The comment says “marginal,” so it’s still not worth paddling out for.
We finally see a flicker of hope on Monday the 10th morning. Swell holds at 5ft from the WNW, period a mediocre 10 seconds, but the wind switches to a clean cross-offshore. The energy is still moderate (530), and it’s marked as “marginal,” but it’s the first time the wave face might actually have a bit of shape. Not a standout, just a “maybe if you’re desperate.”
Tuesday the 11th is back to poor with cross-shore wind. Then Wednesday the 12th morning—this is the closest thing we’ve got to a highlight in the first two weeks. Swell is 5ft from the WNW, period 10 seconds, energy moderate (518), and we get clean conditions with a gentle cross-offshore breeze. The guide gives it a nod with “expect good surf conditions.” It’s not epic, but it’s the cleanest window in a dusty forecast. That morning is your best bet for a session that won’t frustrate you.
After that, it falls apart again. Thursday the 13th through Monday the 17th is mostly poor surf with cross-shore or cross-onshore winds, lumpy chop, and dropping swell. Tuesday the 18th is a write-off. But then Wednesday the 19th morning shows a bigger pulse: 7ft from the NW, period 8 seconds, and the energy jumps to strong (1021). That’s legitimate size for advanced crew, but the wind is cross-onshore and it’s listed as “marginal.” At that size, with that short period and onshore push, it’s going to be a messy, lumpy beast. For experts only, and even then, maybe more of a challenge than a pleasure.
So, truth be told, there’s no single standout session here. If I had to pick the best on offer, it’s that Wednesday 12th morning—clean, 5ft, cross-offshore wind. That’s your window. The bigger pulse on the 19th could be interesting for the bold, but conditions won’t do it any favours.
Hang in there. It’s been a lean run, but forecasts shift, and it won’t stay this flat and messy forever.
Stay salty,
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.
