Alright, Rusty here. Let's have a look at what's coming our way for Deadman's. It's a beach and reef setup, more for the advanced crew, and it takes swell from the NW.

Right off the bat, I gotta be straight with you—this is a frustrating forecast. We've got a solid run of poor surf conditions stretching from the start of July right through the first week. Cross winds, messy swell, and just no love. The water temp is sitting at 62°, which is a solid 7° warmer than usual for this time of year, so that's a very unusual little warm pocket. But don't let that fool you, the surf quality is trash. The combined wave energy is moderate at best, but it's paired with a long period 15-second groundswell from the SW and a woeful cross wind. It just doesn't line up. There's a real gap of about 8 or 9 days where you're better off doing something else.

Now, things start to flicker around July 9th. That Thursday morning, we see some proper size coming in—7ft of swell from the NW, with an 8-second period. The combined energy jumps right up to strong territory. But the wind is cross-on, so it's still a marginal call. Not something to get excited about just yet.

The real standout, the one morning I'd be circling on the calendar, is July 14th. Tuesday morning. Check this out: we get a 6ft NW swell, 8-second period, and the wind is dead calm—glassy conditions. That's a major positive, folks. Combined energy is solid and moderate. For an advanced break like Deadman's, this is where it could get really good. The optimum swell direction for Deadman's is NW, and that's exactly what's on offer. Clean, glassy conditions with that size and direction? That's the pick of the entire forecast. Just keep in mind it's a fairly consistent spot and crowds are often a thing here. The afternoon, though, the wind swings cross-on and it gets messy again.

Through the second week, there's a few more marginal windows—like July 15th and 16th with 7ft to 6ft NW swell—but the wind is always a bit of a spoiler. On July 18th Saturday morning, there's a 5ft WNW swell, 9-second period, with cross winds, so it's nothing to write home about. The energy drops off, too.

For the beginners out there, be careful: from July 9th onwards, we've got swell consistently over 5ft, and it pushes past 8ft a few times, which is expert territory.

So, for the whole 16-day outlook, there's one clear winner: the morning of Tuesday, July 14th. That's your wave. The rest is a waiting game.

Stay frothy,
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.
