Alright, Rusty here. Let’s break down what we’ve got for the next couple of weeks. It’s a bumpy ride with plenty of so-so conditions, so we’ll keep it real.
First thing: the water’s running at an unusual 62°F – that’s much warmer than normal for this time of year at Deadman's. Feels like a warm bath out there.
We kick off Friday, July 10th, with a west-northwest swell around 6ft, but a short 8-second period and a cross-onshore breeze from the west at 15 mph making it choppy and messy. Combined swell energy is 811 (moderate). Honestly, this looks more like a kite-surfing session than a paddling one.
Saturday the 11th and Sunday the 12th drop to about 4ft to 5ft, same direction, with cross winds and light chop. Scores are poor to marginal – energy drops to 179–296. Nothing clean.
Monday the 13th through Tuesday the 14th stay around 4ft to 4ft, but the cross winds and small ripples keep it unappealing. Energy’s weak to moderate (237–295). Still waiting for a decent window.
Wednesday the 15th of July is the first time we get a bit of life. The swell lifts to 7ft from the WNW, still 8 seconds, but with light cross winds in the morning. Combined energy hits 963 (moderate to strong). That’s got some weight, but at 7ft, this is only for experts at an advanced break like Deadman's. The morning’s only marginal though, with a slight cross-chop. The afternoon goes back to choppy cross-onshore. Not a standout, just the biggest bump.
Thursday the 16th has some swell around 5ft to 6ft, but it’s poor – cross-shore chop and moderate breezes. No go.
Then we hit a big lull. From Friday the 17th of July through Monday the 20th, the swell drops to just 2ft. Energy’s still in the 437–571 range, but with those tiny heights and long periods (16–18 seconds) from the SW, it’s barely breaking. A few marginal mornings on the 18th, 19th, and 20th with light cross winds, but you’d be struggling.
Tuesday the 21st of July sees a slight uptick as a new WNW swell fills in at 4ft to 4ft, period 8 seconds. Tuesday morning has light cross winds – the best of a flat bunch – but still only marginal. Energy is 403 (moderate). Not a standout, just a maybe.
Wednesday the 22nd has a similar morning window with 5ft WNW swell and near-calm cross winds at just 3 mph. That’s clean-ish, but still only marginal. Thursday the 23rd and Friday the 24th go back to poor with cross-onshore winds.
The last day, Saturday the 25th of July, finishes with 4ft WNW swell and light cross winds in the morning – again, marginal. Not a great way to end.
So the honest truth: no true standout session in this whole 16-day run. The best pick would be the morning of Wednesday the 15th with that 7ft push, but it’s only for experts and still a bit choppy. Next best is the morning of Wednesday the 22nd with clean-ish conditions on a 5ft swell. There’s a long gap from the 17th to the 21st where it’s mostly tiny and weak. That’s just how it goes sometimes.
Keep the head up – forecasts can shift, and this spot tends to bounce back.
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.
