The Lowdown

Alright, let’s talk Stinson Beach, the next couple of weeks in feet and such.

Right off the bat, there’s a dry spell. From now through Saturday, September 7th, the surf is just no good. We’re looking at weak little SW swells under 3 feet, with cross-onshore winds making everything choppy and messy. Not a single wave worth paddling for.

Then Monday the 7th morning – first real chance. Wind goes light cross-offshore from the ESE, so the water goes clean. Swell is about 3ft from the SSW, with a 14-second period – that’s a proper groundswell with longer waits between sets, but nice shape when they roll in. The energy is moderate. It’s not big, but for a fella willing to sit and wait, it’s your best early window. Crowds at Stinson happen sometimes, so don’t expect to be alone.

Wednesday the 9th morning – another glassy one, NNW wind at 3 mph, flat calm, but the swell is only 3ft from SSW with a 12-second period. A nice little fun session, nothing epic.

The real standout is Thursday the 10th of September in the afternoon. Swell jumps to 6ft from the S, 12-second period, and the combined energy gets strong (1201). Wind is glassy from the WNW at 3 mph. That’s clean, fun, and the best of the first week. Might be a bit much for beginners, but for everyone else it’s choice.

Friday the 11th morning – glassy again, wind calm, 3ft from the SW with a 16-second period and 892 energy. That’s a long-period groundswell, so the waves will have some push and shape. A real nice session in the dawn.

Then it goes flat and poor from the 12th through the 17th. Swell drops under 3 feet, wind goes onshore or cross-onshore, and it’s just choppy junk.

On the 17th of September, Thursday afternoon, a weird one – 6ft from the WNW, but only a 6-second period and 19 mph cross-winds. That’s windswill, not for surfing. More for kite surfers.

Friday the 18th morning – 8ft from the NW, 9-second period, energy is huge (1692), but with a moderate cross-shore wind at 16 mph, it’s lumpy and gnarly. Only for experts.

Then Saturday the 19th of September morning – that’s your second true standout. Glassy, wind from the WNW at 3 mph, 6ft from the WNW with a 9-second period, and energy at 727. Clean, powerful, perfect early. It gets bigger in the afternoon, so get out there early. Crowds might be there, but that’s the price for quality.

Water temp is 62°F, about 4°F warmer than normal – that’s a touch warmer than average, so you might not need the thickest rubber.

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.
