The Lowdown

Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.

First up, the water is sitting at 64° – that's a solid 7° warmer than normal for this time of year, so you're looking at a pretty warm bath out there.

Honestly, the outlook is a bit of a struggle. We've got a long stretch of nothing much happening. From Tuesday the 11th right through to the end of the 16-day window, it's mostly poor surf conditions. The swell energy is moderate at best, with values like 300 to 538, but the wind is almost always cross or cross-on, keeping things choppy and messy. There's no standout session, no day where the stars align.

The only break on the menu is Deadman's, a beach and reef setup for advanced surfers. It's fairly consistent and exposed to the NW, but the swell is tiny and weak for most of the period. The best you'll get is a slight glimmer on Wednesday morning the 12th, with a clean cross-off breeze and a 4ft swell from the WNW with a short 8-second period. It's a marginal call, but it's the cleanest window we've got. The energy is moderate at 347, but the short period means the waves will be a bit weak and choppy.

The rest is just a grind. Swell builds slightly around the 16th and 17th with a long-period groundswell from the SW (15-16 seconds), but the wind is cross-on, ruining any chance of quality. A long-period swell like that would be better suited to a point or reef, but at Deadman's it's just going to close out. The energy is there – 538 on the 16th morning – but the wind kills it.

For the 23rd and beyond, we see a long-period swell from the SW (19 seconds) with very light wind on the 23rd morning, but the swell height is only 1ft. It's too small to do anything with. The 26th morning looks clean again with a cross-off breeze and a 1ft swell from the SW at 19 seconds, but again, it's marginal.

In short, there's no real gem here. The best you can hope for is a clean, small wave on Wednesday morning the 12th or maybe a look at the 26th, but don't get your hopes up. This is a pretty blank run for the area, and it's more normal to have these quiet spells. With the small swell and strong cross-onshore winds, this setup looks more interesting for kite surfing than paddle surfing.

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.
