Alright folks, Rusty here. Let’s have a look at what Deadman’s has in store for us over the coming weeks. I’ll be straight with you – it’s going to be a challenging stretch, with a lot of onshore wind messing things up. The water is sitting at a very unusual 62°, that’s a massive 7° warmer than normal for this time of year, so you can leave the thick wetsuit at home for now.

We’ve got a bit of a wait on our hands for anything worth getting excited about. The first half of the forecast period is rough. From Monday the 6th right through to the end of the following week, the wind is mostly a cross-on or cross-onshore mess, with moderate to fresh breezes. The swell is there, but it’s sloppy. The best we see early on is Wednesday the 8th morning, with a 3 ft SW groundswell at a very long 18 seconds. The wind is a light cross-shore, so there’ll be a slight cross-chop, but it’s only marginal. The combined wave energy is moderate (1231). For most other days in that first week, it’s just choppy and poor.

Around the 9th and 10th, the swell picks up a bit, with waves reaching 6 to 7 ft from the WNW on the 9th, but the period drops to a short 8-9 seconds and the wind is nearly always cross-on. Thursday morning the 9th might be the pick of a bad bunch with a 6 ft WNW swell, a light cross breeze, and moderate energy (1239), but the short period will make it dumpy and hard to connect with. This kind of short-period, onshore wind combo at a beach and reef break is honestly looking more interesting for kite surfing right now than proper paddle surfing.

You have to wait all the way until Friday the 17th for the first real standout. The morning shows a solid 8 ft WNW swell, with a moderate 8-second period and strong combined wave energy of 1393. The wind is light and cross, which is the best we’ve seen in ages. That means the surface will be clean with just small wind ripples. It’s a big swell, over 8 ft, so this is for experts only – think powerful, critical waves. This is the one day to circle on your calendar.

After that, the following weekend sees the swell and period drop off again quickly. By the 18th, we’re back to a 5 ft WNW swell with a 9-second period, and the light cross wind makes it worth a look for the more experienced surfer, but it won’t be as special as the 17th. The final few days into the 21st are quiet, with small 2 ft SW groundswells and onshore winds returning, so not much to write home about.

Keep your eyes on Friday the 17th. That’s the best session on offer, but it’s a long-range call so don’t nail your plans to it just yet.

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.
