The Lowdown

G’day, Rusty here. Let’s get into it for Deadman's.

Alright, look, we’ve got a tough run ahead. The 16-day window starts quiet, and honestly, it’s a bit of a struggle to find a proper session. The water is sitting at 63°F – that’s about 7°F warmer than usual for this time of year, so pretty unusual, like a warm bath for late July.

Saturday 25th & Sunday 26th
We kick off Saturday morning with a clean sky but a cross-on wind from the west at 9 mph. The swell is a small 3ft out of the southwest with a very long 21 second period. That’s a proper groundswell, but the wind is messing it up, making it choppy. The combined energy is moderate (827). It’s a write-off, really. The afternoon doesn’t get any better with the wind picking up to 16 mph. Sunday is more of the same: cross-on wind, 3ft swell, not much to get excited about.

Monday 28th to Tuesday 29th
Monday morning offers a glimmer: 3ft from the southwest, but the wind is still cross-on. It’s marginal. The afternoon gets messy again. The real frustration is Tuesday, where the morning has a light breeze (6 mph) and a 4ft southwest swell (18 seconds, 943 energy) – it’s *almost* there, but the cross-on direction keeps it from being clean. Wednesday afternoon sees a spike in swell height to 7ft from the WNW, but that’s a short period (8 seconds) windswell, really juiced up (1114 energy), and the cross-on wind at 16 mph makes it a washing machine. That’s expert-only territory at best, and honestly, it’s more of a kite-surfing setup than a paddling one.

Thursday 30th to Friday 31st
Thursday and Friday see a drop in swell energy (down to 188-402) with short-period WNW windswell. The wind is cross or cross-on, so it’s a continuous run of poor conditions.

Saturday 1st August – The One Standout
Finally, a ray of hope. Saturday morning, 1st August, is the standout of the whole outlook. It’s glassy. Flat calm. The wind is a whisper from the west at 3 mph. The swell is 4ft from the WNW with an 8-second period. The energy is low (228), but that glassy surface will make it feel so much better. It’s surfable, but ordinary. For Deadman's, a beach and reef break, that short period means the waves won’t be super grunty, but with no wind, it’ll be clean and fun for an advanced surfer. The crowds are often at this spot, so expect company. This is the best we’ve got.

Sunday 2nd August onward
After that one morning, it’s back to the grind. Sunday morning has a bigger 6ft WNW swell but with a cross wind at 6 mph, making it marginal. The energy is moderate (573). The rest of the week into the second week sees a slow decline: swell drops to 1ft by Thursday 6th, with energy falling to as low as 64 by Saturday 8th. The wind is consistently cross or cross-on, and the only real highlight is a small 1ft southwest swell with a very long 16-second period on Saturday afternoon 8th August, but it’s still cross-on and choppy.

The Gap
After that glassy Saturday morning, there’s a long gap of about 8 days where nothing is really recommendable. It’s a proper blank run.

So, bottom line: if you’re desperate, the glassy Saturday morning 1st August is the only time to paddle out. The rest of the 16 days is a write-off. Conditions can change, but for now, it’s a tough watch.

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.
