The Lowdown

Alright folks, Rusty here. Let's take a look at what the next couple of weeks are serving up for us at Deadman's.

Right off the bat, I gotta be straight with you – the next couple of weeks are going to be a serious test of patience. We've got a long stretch of dribble and poor conditions ahead. The water temp is sitting at 62°, which is much warmer than usual for this time of year, so that's one small silver lining, but it's about the only one for a while.

The first real chance for anything decent doesn't show up until Sunday morning the 19th of July. It's small, with a 2ft swell coming from the west. The big story here is that very long period of 15 seconds, bringing some groundswell energy, with a moderate combined energy reading of 425. The light cross-shore wind will be key here, keeping things clean. But honestly, it's marginal and probably only for the die-hards. The water temp anomaly is a massive 3° warmer than average, which is very unusual for this area.

After that, we slide straight into a run of marginal-to-poor conditions from Monday through Thursday. The swell sticks around the 2-3ft mark from the SW, but the cross and cross-onshore winds will chop things up. The wind won't be our friend.

Now, if you can wait, the outlook gets a bit more interesting. The end of the week, specifically Friday the 24th of July morning, we've got a 2ft swell but look at that period – 24 seconds! That's a seriously long-period groundswell, and the combined energy is up at a moderate 686. The wind is a gentle cross-shore, so it could be clean. But keep in mind, with a period that long, Deadman's being a beach and reef setup might have waves breaking a bit too straight. Even so, it's the cleanest option we've seen.

The following Saturday morning the 25th of July builds on that. Swell ticks up to 3ft from the SW, with another very long 21-second period and a combined energy of 884. Again, the cross-shore wind holds. This window from Friday the 24th through to Sunday the 27th of July mornings is your best bet. The swell holds around 3ft with 18-19 second periods and strong energy readings (1065 on the 26th), paired with light cross-shore breezes.

But don't get too excited. The afternoons in this stretch are all blown out by moderate cross-onshore winds.

Heading into the second week, the consistency drops off a cliff. The swell windows become smaller, and the onshores dominate. Monday the 28th of July morning might have a tiny clean window with 3ft swell and a light breeze, but by the afternoon it's game over. The rest of the month and into August looks like a write-off with poor conditions and weak energy.

The only real standout here is the window from Friday the 24th to Sunday the 27th of July. The swell direction is from the southwest, which is bang on the optimum for Deadman's. The light morning winds will give you clean conditions, even if the swell size is on the small side. For an advanced spot that's fairly consistent, this stretch of mornings is all we've got. Expect crowds though.

If the wind and swell line up right, the kite surfers might be having more fun in the afternoons when the chop picks up, but for paddling, be patient.

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.
