Alright folks, Rusty here. Let’s get into it.

Right off the bat, I gotta be straight with you – this 16-day window for Deadman’s is a tough one. The water is sitting at a crazy 62°F, which is a whopping 7°F warmer than usual for this time of year. That’s a big anomaly, and it’s the only thing that feels out of the ordinary. The surf itself? A real grind.

The period kicks off with a bit of a tease on Wednesday afternoon, July 8th. We’ve got a 3ft swell from the SW, but it’s a long-period groundswell at 16 seconds, which sounds promising until you pair it with a 25 km/h cross-on westerly. The combined energy is low (815), and it’s just choppy, poor surf. Not worth wetting a suit.

Thursday morning, July 9th, looks a little more interesting. A 7ft NW swell sneaks in, but the period is only 8 seconds – short-period wind swell. The combined energy jumps to 1497, which is moderate, but it’s a cross-shore breeze at 10 km/h. The forecast calls it “marginal,” and honestly, with those conditions, it’s more of a sloppy, lumpy session than a clean one. The afternoon goes back to onshore chop.

Friday and Saturday, July 10th and 11th, follow the same pattern. Swell hangs around the 5ft to 7ft mark from the WNW, but the winds are either cross or cross-on, and the ocean is just a mess of cross-chop. The energy numbers are weak to moderate (469 to 1023), and there’s no real window of glassy, clean conditions.

Sunday morning, July 12th, is probably the least bad of the first week. We’ve got 8ft from the NW, but it’s still short period (8 seconds) and the wind is a gentle 15 km/h cross-on. The combined energy is 1363, showing a bit more push, but it’s going to be a choppy, bumpy ride. The afternoon fills back in with onshore winds.

The whole first week is a write-off for clean waves. There’s nothing that stands out as a genuine good session. The second week is even quieter.

From Monday, July 13th, through to the end of the period, the swell drops and the wind keeps blowing from the wrong direction. The heights drop to 5ft and below, and the energy figures fall into the weak range (under 750). There’s a brief moment on Saturday, July 18th, where we get a 2ft swell from the W with a very long period of 17 seconds, but it’s a tiny wave and the energy is still weak (647). That’s a groundswell that would be better at a point or reef, not a beach and reef setup like Deadman’s.

The last few days of July are just small, weak, and cross-shore. The 23rd sees a 5ft WNW swell return, but it’s back to short period (8 seconds) and the wind is onshore again.

The Bottom Line: There is no standout session in this 16-day window. The nearest thing to a “best on offer” would be Thursday morning, July 9th, with that 7ft NW swell, but it’s a short-period wind swell with a cross breeze. It’s not clean. For a break that’s fairly consistent and fairly exposed, this is a poor run of luck. The conditions are just too messy for a proper paddle session. Honestly, with that much wind and chop, this setup looks more interesting for kite surfing than paddle surfing.

I’m Rusty. I’ll be back when the charts look better.

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.
