The Lowdown
Alright, grab a seat and let me, Rusty, walk you through what's on offer for the next couple of weeks. It's a pretty quiet start, so don't expect much action for a while.
We're looking at Deadman's, a beach and reef setup that's for the advanced crew. It's fairly consistent here, but honestly, the next seven days or so are looking pretty grim. The key issue is the wind, which is mostly cross or cross-onshore, and the swell is just not performing. The wave energy stays weak to moderate, with the combined energy readings in the 300s to 400s for most of the first week, but it's all jumbled up. The water temperature is about average for this time of year, so nothing wild there.
The whole first week, from Wednesday the 12th right through to the following Monday, is a write-off. The scores are all zero or a one at best. The morning of the 12th has a 4ft swell from the WNW, but it's only 8 seconds and cross-shore, so it's just a messy, marginal option. It gets worse from there. There's a brief glimmer on the morning of Sunday the 16th with a 3ft SW swell (16 seconds) and a light breeze, but the wind is still cross-shore, keeping it just "marginal." The energy is moderate at 493, but it's not enough to get excited about.
After that, it's more of the same – poor conditions and cross-onshore winds until we hit a drought. There's a big gap with no real surf from about the 18th through to the 23rd, with only a couple of "marginal" tags on the 24th and 25th mornings.
Now, let's talk about the one true standout. If you're an expert and you've got some patience, Monday the 24th of August is your best bet. The morning is a bit meh, but in the afternoon, a 5ft swell from the WNW rolls in. The period is a short 7 seconds, which is a bit of a bummer, but the energy is moderate at 373. The wind is a clean, light cross-shore, which is about as good as it gets here. The swell direction is NW, which is the optimum for Deadman's, so this could be the only time the setup really works. Just be aware that crowds are often a problem here, so you'll have company.
Other than that, the morning of the 25th offers a similar 4ft WNW swell with a light breeze, but it's still just a "marginal" call. The rest of the window is a steady stream of "poor" labels. For a spot that's fairly consistent, this is a real drought. But it tends not to stay poor for long around here, so fingers crossed.
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.
