Right, let’s have a look at what’s on the cards for the next couple of weeks.

Straight up, the outlook is a tough one. The only break in the mix is Deadman’s, a beach and reef set-up that’s been copping it from the wind most of the time. The first few days are a write-off, to be honest. The water is sitting at 63°, which is a massive 7° warmer than normal for this time of year, so that’s a real standout.

Thursday afternoon is a no-go: 6 ft swell from the WNW, but with a strong cross-onshore wind of 15 mph, the surface is just chopped out. The combined wave energy is moderate at 753.

Friday, July 10th, is the same story. A bit more size in the morning at 7 ft, but the wind is still cross-onshore, and the wave comment is poor. Afternoon drops to 6 ft, but the wind stays on it. The energy is high in the morning at 1116, but it doesn’t matter if the wind is ruining it.

Saturday morning, July 11th, is the first real glimmer. You’ve got a 6 ft swell from the NW, and the wind drops right back to a light breeze, but it’s cross-shore, not offshore. It’s marginal. The energy is moderate at 758. If you’re desperate for a paddle, this is your best bet for the first week, but it’s not going to be classic.

The rest of the first week and into the second is a lot of average conditions with cross-shore or cross-onshore winds and consistently poor to marginal wave comments. Sunday morning, July 12th, has a 5 ft swell with a light breeze, but it’s still cross-shore. Wednesday morning, July 15th, bumps up to 7 ft, but again, the wind is light cross-shore, giving a marginal call.

The biggest size comes in on Thursday morning, July 16th, with a 8 ft swell from the NW and a light breeze, but the wave comment is still only marginal. That’s a big wave for Deadman’s, and with the offshore direction being SE, it’s not going to be clean. For experienced surfers only, and even then, be wary.

Then, from Friday, July 17th, the swell drops off a cliff. We’re looking at 2 ft, with a very long period around 17-18 seconds, which is pure groundswell. That kind of swell at a beach and reef break like Deadman’s will just break too straight and fat. The wind is still a problem. The combined energy drops to low values in the 400s.

There’s a long gap of several days where there’s nothing worth paddling for. The 20th of July shows a little bump back to 5 ft, but it’s cross-on and poor.

The 23rd and 24th of July have a bit more life, with 6 ft to 7 ft swells, but the wind is still cross-shore, and the wave comments are only marginal at best. The energy is moderate, around 388 to 715.

The honest truth is there are no standout days in this 16-day window. The wind is just too persistent from the wrong direction. If you’re a regular, you know it won’t stay poor forever, but for now, save your energy. The only real positives are the unusually warm water and the occasional light wind morning, which is still not offshore.

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.
