The Lowdown
G’day, it’s Rusty here. Let’s not beat around the bush—Stinson Beach is looking pretty quiet for the next couple of weeks. You’re going to have to pick your moments carefully, because there’s a long stretch of nothing at the start, and the few days with some size are mostly messy. If you’re new to this, just know that this sort of flat spell is pretty normal for this stretch of coast, and it won’t stay this way forever.
First up, the early days. The 12th and 13th have a tiny bit of swell, maybe 2 feet, but the wind is cross-onshore and the surface is choppy. The water is sitting at a warm 66°F, which is about 7°F warmer than normal for this time of year—that’s a real treat. But the waves themselves are not worth the paddle. On the 14th and 15th, the swell bumps up a little to around 5 feet, but it’s short-period windswell, with a cross-onshore breeze, so it’s lumpy and disorganised. Not a beginner wave, and not even that fun for the more experienced crew.
Then we hit a dead patch from the 16th to the 20th. Swell drops to under 2 feet, and even though there are some long-period groundswells in the water, there’s just no energy behind them. The winds are all over the shop, keeping things bumpy. Some mornings are lighter, but the lack of size means you’re just floating around.
The first sign of life is on the 21st of September, when we get a bit more size—about 6 feet—and a light wind in the morning. But it’s still short-period, so it won’t be beautiful. The real window to keep an eye on is the 25th through the 27th. The morning of the 25th is clean with a light cross-offshore breeze and around 2 feet of swell. It’s small, but it’s the most surfable thing we’ve had in a week.
The standout, and I can’t stress this enough, is the morning of Sunday the 27th. We’ve got around 3 to 3 feet of swell, coming from the southwest, with a very long 15-second period. And the wind is dead calm—glassy. This is the session to circle. It’s not big, but it will be clean and have some proper push to it. The 26th morning is also good—small, clean, glassy—so mark that one down too. For the beginners, these are your days. For the experts, it’s not huge, but the quality will be there.
Remember, Stinson is a beach break, and a long-period swell like that can sometimes close out and be a bit straight. But it’s the best we’ve got. And with the water so warm and the crowds likely on the weekend, get there early for that Sunday. There’s a lot of flatness to get through, but those last couple of mornings make it all worthwhile.

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.
Stinson Beach is 10 km (6 miles) from the city of Corte Madera. If you plan a vacation in Marin County, look for hotels and other accommodation in Corte Madera. Corte Madera has rooms for a wide range of budgets as well as car hire and transport links.
