The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day window for Stinson Beach, and I’ll be straight with you: it’s a pretty lean stretch. The first solid bit of action is a long way off, and even then, it’s not going to be firing.

The overall pattern is one of small, messy waves with a lot of cross-onshore wind. The water temp is sitting at 65°F - that’s a whopping 7°F warmer than normal for this time of year. That’s seriously unusual, like the ocean forgot what season it is.

For the first eleven days, from Friday the 11th through to Monday the 21st, it’s a real grind. The swell is tiny and the wind is constantly onshore or cross-onshore, making it choppy and blown-out. There’s really nothing to get out of bed for. The combined wave energy is moderate at best, hovering between 250 and 500 (moderate energy), but it’s all just messy, wind-affected slop. You’ll want to sit this one out.

Now, the one true standout, and I mean the *only* one that makes me smile, is the morning of Wednesday the 23rd of September. It’s still a week and a half away, so don’t book the day off just yet, but the model is showing some promise. We’re looking at a clean 5ft swell out of the west-northwest with a period of 8 seconds. The kicker? The wind is dead calm - glassy conditions. That’s a major win. The combined energy hits 553 (moderate energy), and for Stinson, that’s as good as it’s going to get this month. It’s not going to be a monster day, but that glassy morning with some waist-to-chest high sets could offer up some clean walls for a beginner-to-intermediate surf. Just keep in mind, crowds are *sometimes* a thing here, so you might have some company.

Sadly, that’s your lot. The rest of the month just fades back into tiny, wind-blown dribble. Honestly, it’s a stretch where the beach setup, with the constant cross-shore winds on the bigger days, looks more interesting for a kite than a paddle.

Keep your chin up, the forecasts can always change.

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.

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.
