Righto, it's been a bit of a flat spell, but we've got some action brewing. The next few weeks are a bit of a mixed bag, with some solid lumps showing up mid-week, but the wind is going to be the main talking point. Let's get into it.

The first sign of life is a pulse of swell arriving on Wednesday morning, July 8th. The water is a toasty 62°F – that's much warmer than normal for this time of year, a nice little bonus.

The standout window is going to be Wednesday morning, July 8th at Deadman's. We're looking at a 7ft swell out of the WNW, but here's the catch – it's a short-period, windswell-style wave at 8 seconds. That being said, the wind is light and cross-shore, so the surface will be clean. The combined energy is pumping at 1316 (strong to very strong wave energy), so there's plenty of juice. It's an advanced spot, so keep that in mind; this size is really only for the experienced crew. Crowds are likely here, so get in early.

Thursday morning, July 9th, offers a similar story with a 6ft WNW swell, same 9-second period, and light cross-shore winds. The energy is still strong at 1263, but it's still a short-period groundswell, which can make for a bit of a lumpy, less organised wave at this beach-and-reef setup. It's a good option if you missed Wednesday.

As we push into the second week, the swell drops off but hangs around in the 4ft to 6ft range. The wind, however, turns more onshore and choppy, making it a tough call for a good paddle. There's a window on Friday morning, July 10th, with a 6ft WNW swell and light cross-shore wind, but the energy is dropping to 723 (moderate) and the period is still a short 8 seconds. It's a marginal call.

From Saturday, July 11th onwards, the surf gets smaller and the wind stays messy. The 5ft to 6ft waves are still there, but the cross-onshore and choppy conditions will make it hard work. This setup looks more interesting for kite surfing than paddle surfing for many of those afternoons.

A brief glimmer shows up on Friday morning, July 17th, with a 4ft WNW swell and a longer 9-second period, but the wind is a moderate cross-shore, which will put a chop on it. The energy is moderate at 723.

The final week fades out with small, weak swells around 2ft to 4ft and the wind staying onshore. It's a bit of a letdown after that mid-week pulse.

So, to wrap it up: Wednesday morning, July 8th is your best bet. Get on it before the wind ruins the party.

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.
