The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day window that’s a bit of a mixed bag, but there is a standout window if you’re patient.

We’re looking at Deadman’s, a beach and reef setup that’s advanced territory. The water is sitting at 61°F right now, which is much warmer than normal for this time of year, so you’ll be surfing in a t-shirt or a shorty for sure.

The first real opportunity to get out is on Sunday morning, August 2nd. The swell is 7ft from the WNW, with a period of 9 seconds, and a combined energy of 748 (moderate). That’s a solid head-high to just overhead on the best sets. The wind is a light cross from the SW, only 6 mph, so it’s not glassy, but it’s manageable. The water’s warm, but the comment says marginal surf due to questionable tide. It’s worth a look if you’re an advanced surfer, but it’s not the cleanest it could be. That afternoon, the wind picks up to 12 mph and the chop gets nasty, so morning is the only window.

Monday morning, August 3rd, is the real standout for the first week. The swell drops a touch to 6ft from the WNW, 10-second period, combined energy 615 (moderate). The wind is a light cross-offshore from the SSW at 6 mph, which will clean it right up. The wave comment says expect good conditions. This is your best bet for the early part of the forecast. The break is fairly consistent, and with an offshore wind, it’ll be peeling nicely. Crowds are often, so expect a few others out there.

After Monday, the surf drops off hard. From Tuesday, August 4th, through to Saturday, August 8th, we’ve got a stretch of weak, small waves, mostly under 4ft, with cross-shore winds and chop. Combined energy drops to 163 to 323, which is weak. It’s a full week of poor conditions, so don’t bother paddling out.

Then, Sunday, August 9th, the swell comes back up. Morning sees 6ft from the WNW, 10 seconds, combined energy 720 (moderate). But the wind is a moderate cross from the SW at 12 mph, and the comment says marginal surf. The afternoon gets worse with a fresh breeze at 18 mph and lumpy cross-chop. It’s big, but it’s not clean. For a beach and reef, this kind of wind and size will be a mess, likely more interesting for the kite crew than paddle surfers.

Monday, August 10th holds 5ft to 5ft from the WNW, but again, wind is 12-15 mph from the SW, cross-shore, and the comment says poor. Not worth it.

From Tuesday, August 11th onwards, the swell goes back to weak and small, with occasional bumps of 5ft on the 13th, but the wind is always cross or cross-on, and the energy is moderate at best. The second week is a write-off for quality surf. Even the long-period swells that show up on the 16th and 17th (16 seconds and 14 seconds) are only 3ft and 1ft, so they’ll be weak and straight at a beach break.

So, to sum it up: the only true standout is Monday morning, August 3rd. Get out there early for clean 6ft WNW swell with light offshore winds. That’s your window. After that, it’s a long stretch of chop and small stuff. Keep an eye on the sky, but for now, that’s the call.

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.
