The Lowdown

Alright folks, Rusty here. Let’s have a look at the forecast. I gotta be straight with you: the next couple of weeks are looking pretty rough for a proper paddle session. The only spot we’ve got any intel on is Deadman's, and to be honest, the waves are gonna be a struggle for most of this period.

Right now, we’re looking at a long stretch of poor to marginal conditions. The swell we’ve got coming in on Friday the 17th is a messy 5ft from the WNW with a short, weak period of 8 seconds. The combined energy is moderate (652). It’s not doing us any favors. The water is a very unusual 63°, which is much warmer than normal for this time of year. The wind is cross-shore, and it’s choppy. It’s not what you’d call clean surf. Saturday the 18th drops right off to a tiny 2ft, and while the period jumps to 17 seconds, that’s a long-period groundswell that will likely just close out or run straight at a beach-and-reef setup like Deadman's. The wind stays cross, so it’s bumpy and weak.

We’ve got a real gap here. From Sunday the 19th through to about Wednesday the 24th, it’s mostly tiny, weak, and messy. You’ll see some days with a 2ft to 3ft swell, but the wind is often cross-onshore, and the energy is low (down to 26 in spots). There’s a moment on Tuesday the 21st morning where the wind goes glassy, but the swell is a pathetic 2ft from the NW with only 64 combined energy. Not enough to ride.

The one bright spot – and I mean the only one that’s worth a mention – is looking further ahead. On Tuesday the 28th of July, the morning session shows a 4ft swell from the SW with a moderate 18-second period. The combined energy jumps up to 844, which is solid. The wind is a light cross-shore, so it might clean up. The afternoon is a bit bigger, with energy hitting 1097, but the wind turns cross-shore and choppy. Even then, it’s only rated as marginal. Then into Wednesday the 29th, we see that 4ft SW swell holding, and the morning wind is gentle cross-shore again. The energy is 971. That’s the best of the bunch. It’s still not a classic, but if you’re desperate, that Wednesday morning the 29th is your best bet. The swell direction from the SW is on the money for Deadman's, and that long period (16-18 seconds) should bring some decent lines, though you’ll want to be on a point or reef, not the beach.

Other than that, we’ve got a bit of a pulse on Thursday the 30th morning with a 5ft from the WNW, but the period is short (9 seconds) and the energy is moderate (819). The wind is light, so it might be a bit lumpy but surfable for the more advanced crew. After that, we fade back into weak, small dribble.

So, the standout here is Wednesday morning the 29th of July at Deadman's. The rest of the window is mostly a write-off. If you’re a beginner, forget it – most of the decent swell is over 5ft and the periods are long, which is tricky. For the experts, that Wednesday morning and maybe Thursday the 30th morning are your only realistic windows. It’s not a great run, but the forecasts can change.

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.
