The Lowdown
G’day, Rusty here, and I’ve gotta be straight with you – the outlook for Deadman’s over the next 16 days is a bit of a slow burn. This is a beach-and-reef setup for the advanced crew, and it’s fairly consistent, but the conditions are mostly fighting it. We’ve got a few dates where it gets close to being worth a paddle, but nothing’s a clear winner. The first real sniff of anything is on Sunday morning, August 9th.
The overall pattern is dominated by a mix of WNW and SW swell directions, with the best period of swell energy hitting around Sunday morning, August 9th. That morning, we’ve got a 5ft swell from the WNW, with a period of 10 seconds and a combined energy of 474 (moderate). It’s a bit of a lumpy cross-shore wind from the WSW at 6 mph, so it’s not glassy, but it’s the cleanest looking window in the first week. The water temp is about average for this time of year – nothing wild to report there.
Another morning to keep an eye on is Thursday, August 13th. It’s a bit smaller at 4ft, but the swell is from the WNW with a longer period of 11 seconds (groundswell), and the combined energy is 438 (moderate). The wind is a cross-offshore breeze from the SSW at 9 mph, so it’s clean. That’s a standout for a more organised wave, but the size is modest. For the advanced crew, this could be a fun session.
The week of August 18th to 22nd shows a few mornings with 5ft swells, but the wind is always messing it up – cross-shore or cross-onshore, never clean. The period drops to 7-9 seconds, so it’s short-period, weak stuff. Not worth the drive.
The real size shows up on Wednesday afternoon, August 20th, with a 7ft swell from the WNW, but it’s got a period of only 6 seconds and a messy cross-onshore wind. That’s a big, chunky, ugly wave – only for the experts, and even then, it’s borderline dangerous. The combined energy hits 633 (moderate), but the quality is poor.
If I had to pick one true standout, it’s Sunday morning, August 9th. It’s not perfect, but it’s the best combo of size and relatively light wind. Thursday morning, August 13th, is a close second for cleaner conditions on a smaller, longer-period swell. The rest is a lot of average to poor surf.
So, keep the board waxed for those two mornings, but don’t expect a classic. The gaps are a few days at a time where you’re better off doing something else.
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.
