The Lowdown
Alright, Rusty here. Let’s talk about the next couple of weeks for Stinson Beach.
Overall, it’s a frustrating stretch ahead. We’ve got a lot of days with some push from the swell, but the wind is almost always cross-onshore and the conditions are rough. The water’s sitting at 61° which is a touch warmer than normal for the start of September, so at least it won’t be freezing out there.
The opening is grim. Wednesday and Thursday are a write-off – tiny 1ft to 2ft swell coming from the SW with a very long 16 to 19 second period, but the wind is junk, cross-onshore and choppy. The combined swell energy is moderate (193 to 442), but it doesn’t matter with that messy sea surface. Friday morning, September 4th, is the first real chance to look at it. The swell picks up to 3ft from the SW with a long 18-second period, and the wind goes light cross-shore. That cleans it up a bit, and combined energy is strong at 821. It’s still only a marginal call for a beginner-friendly spot like Stinson, but if you time it early, you might find a few clean lines. After that, it’s back to mostly choppy, cross-onshore junk through the weekend and into the next week.
The end of the second week, around Monday September 14th through Wednesday September 16th, things get bigger. Swell bumps up to 6ft to 8ft from the WNW, but the period drops short to 7–10 seconds. That’s a windswell, not groundswell, so it’ll be lumpy and sectiony. The combined energy hits very strong levels, peaking at 1108 on the afternoon of the 15th. The wind stays cross-onshore though, so it’s going to be a messy, choppy mess – honestly more interesting for kite surfing than paddle surfing. These waves at 8ft are only for experts, and even then, the quality looks poor.
Friday September 17th afternoon has a nice 2ft SW swell with a 21-second period (very long), and combined energy is strong at 700, but the wind is back to moderate cross-onshore, so it won’t be smooth.
The only stand-out window in this whole 16-day run is Friday morning, September 4th. Light cross-shore wind, 3ft of long-period SW swell, clean early. That’s your best shot, but keep expectations humble for Stinson. Crowds are sometimes an issue on a decent day.
Stay patient, this run looks more like a blown-out rest than a proper swell window.
Rusty.

Information about the Stinson Beach Surf forecast
The above surf forecast table for Stinson Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Stinson Beach can be found by selecting the local surf guide option on the grey menu. Our Stinson Beach 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 (Stinson Beach) 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 Stinson Beach 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.
