The Lowdown
G'day, Rusty here. Look, I've had a good hard look at the prospects for Deadman's over the next couple of weeks, and I gotta be honest with you – it's a pretty grim stretch. We're talking a long, long run of days where the conditions just aren't coming together for anything worthwhile. You're looking at a solid block of poor surf from Tuesday the 4th of August all the way through to at least the end of the first week. There's a glimmer on the horizon, but it's a fair way off.
The water is sittin' at a balmy 62°F – that's much warmer than normal for this time of year, so you won't need a thick suit, but that's about the only thing going for us.
Let's walk through it. Starting Tuesday morning, the 4th of August, we've got a 4ft swell from the WNW, but it's a weak 9-second period and the wind is a cross-shore from the SW. The energy is weak at 281, and it's just marginal at best. The afternoon gets worse with a stronger cross-shore and a score that's a flat zero. Wednesday through to the end of that first week is the same sad story – tiny swell, poor winds, and the energy is either weak or moderate at best. We're talking about a full stretch of days with nothing to recommend.
Then, finally, we get a bit of a pulse. Sunday the 9th of August shows a pulse of 5ft swell from the WNW, lifting the energy to 474 (moderate). But the wind is still cross-shore in the morning with a light breeze, and the afternoon gets chopped up. It's still only a marginal call. The best chance looks like Monday the 10th of August. The morning has a 5ft WNW swell, and the wind is a cross-offshore breeze from the SW at 12 mph, giving us some cleaner lines. The energy is strong at 517. But it's still only a marginal call, and the afternoon reverts to poor conditions. This is the standout of the entire forecast, but it's not a classic.
The rest of the second week is more of the same – small WNW swells, cross-shore winds, and mostly poor conditions. By the 18th of August, we're down to 1.0ft of swell with barely any energy at 58. It's a long, flat spell.
So, bottom line: for a place that's a fairly consistent advanced spot, this is a real dry spell. The only real window is the morning of Monday the 10th of August, with a 5ft WNW swell and a cleaner cross-offshore wind. It's an advanced wave, so that 5ft is doable, but keep your expectations in check. The rest of the time, you're better off checking the forecast again later. This kind of blank run can happen, but it won't last forever.
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.
