The Lowdown

Alright, let's get into it. This forecast covers Deadman's, a beach and reef setup that takes a NW swell and needs some decent conditions to really fire.

Straight up, the start of this period is a bit of a write-off. The first week is mostly a bust. We've got a bit of weak swell coming in, but the wind is just wrong, mostly from the W or WSW, turning what little surf there is into a choppy mess. Don't even bother looking at the first few days.

The first glimmer of hope is late in the week. On Thursday morning, the 10th of September, things take a turn. The swell drops a bit to 2ft out of the SW, but it's a long period groundswell at 17 seconds, packing some moderate energy (504). The wind goes glassy – dead calm – which is magic. This is your clean window for the week, a rare moment of calm before the afternoon onshores kill it. Water temp is 62°, which feels much warmer than usual for the time of year, so you can get away with a thinner suit.

Then we have a long drought of poor conditions straight through until Saturday morning, the 12th of September. We get a clean looking morning with a light cross-off shore wind. The swell is small, only 2ft from the SW, but it's a solid 14-second period groundswell (moderate energy at 409). It'll be pretty small, but clean and rideable on the right tide. But again, by arvo the onshores are back. The real next stand-out is way out there.

Thursday morning, the 17th of September – now we're talking. This is the standout. The swell jumps to 5ft from the WNW, which is straight down the pipe for this spot. It's got a solid 10-second period and strong energy (573). The wind? Glassy again. Zero wind. This is for the crew who can handle it – at 5ft it's starting to rattle the cage, but on the reef at Deadman's with no wind, it's going to hold up beautifully. It's a week and a half away, so keep an eye on it, but this looks like the best session on offer.

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.
