Alright, Rusty here again, dialing it into feet and Fahrenheit for you.

First up, the water is sitting at 61.2°F right now, which is a solid 5.9°F warmer than usual for this time of year. That’s a proper anomaly, way above average, so you’re not gonna need a thick steamer.

Right off the bat, the start of the period is a write-off. From Sunday the 5th right through until Tuesday morning the 7th, it’s just poor surf conditions. You’ve got weak, long-period SW groundswell (18 seconds) running at only 2ft with cross or cross-onshore winds messing it up. Combined energy is weak, sitting between 404 and 695. Not worth paddling out.

Wednesday the 8th morning shows a pulse of new swell—7ft from the NW, but the period drops to a short 8 seconds. The combined energy jumps up to 1397 (moderate), and while the wind is a gentle cross-shore, the setup looks more interesting for a kite surfer than a paddle surfer given the poor wave quality notes and the cross-onshore chop later in the day. Not a standout for us.

The main event, the one that gets my heart rate up, is Thursday the 9th morning. We’ve got the biggest swell of the whole run: 8ft from the NW with a period of 9 seconds. The combined energy hits 2018, which is solid. The wind is light and cross-shore from the WSW at only 6 mph, keeping it clean. Now, at 8ft, this is expert territory—it’s gonna be big and powerful, not for the faint of heart. The break is a beach and reef setup, and while the direction is NW (not the optimum NW that the guidance loves), the size and the light wind make this the best session on offer. If you’re skilled, get out there.

After that, the surf quality drops off hard. The mornings on Friday the 10th and Saturday the 11th have some size (6ft and 5ft) but the wind is either cross or the conditions are marginal. Saturday morning the 11th does have a window of clean surf with cross-offshore winds (SSW at 9 mph) and 5ft of WNW swell, but the combined energy is weak at 441 and the quality is only rated as “expect good surf,” nothing special.

From Sunday the 12th all the way through to Friday the 17th morning, it’s a long stretch of poor and marginal conditions. The swell hangs around between 4ft and 7ft, but the winds are mostly cross-onshore or choppy cross-shore. There’s a long gap of almost a week with no real recommendations.

Friday the 17th morning is a tiny flicker of hope. We get a glassy morning with a slight cross-offshore breeze (SSW at just 3 mph), and a long-period W groundswell (18 seconds) at 2ft. The waves will be clean and lined up, but with a combined energy of 592 (weak), it’s a longboard or a mini-mal kind of day. The long period means long lulls, but it’ll be beautiful out there.

The last few days, from the 18th to the 20th, are back to weak cross-shore junk. The 20th sees a bump back up to 5ft from the WNW, but with cross-shore winds and poor quality again.

The Standout: Thursday the 9th morning. That 8ft NW swell with light wind at Deadman's is your one true shot at something memorable. It’s an expert-only day, but for those who can handle it, it’ll be pumping.

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.
