The Lowdown

Alright, this is Rusty. Let's get into it.

Right off the bat, I gotta be straight with you – Stinson Beach is looking pretty grim for the next little while. We've got a long stretch of real "meh" conditions ahead, and for the first several days, it's a total write-off. The swell is there, but the wind is just making a mess of things.

From today, Thursday the 13th, right through to Monday the 17th, forget about it. We've got a mix of cross-on and onshore winds, with swell heights barely pushing 4 feet. The water temperature is about average for the time of year, nothing to get excited about there. The wave energy is weak to moderate, but the real killer is the wind. It's just choppy and junky. There’s nothing to paddle for.

Things get a little more interesting on Tuesday the 18th. We see a pulse of NW swell bumping up to 6 feet, but it's short-period at 8 seconds and the energy is moderate. The wind is still cross-on for the morning, but it's light, so there might be a window. This swell direction isn't ideal for Stinson – it prefers a good SW wrap. Still, for a beginner spot, 6 feet might be pushing the limits for some.

The standout in this whole outlook is actually Wednesday the 19th morning. We get a solid 7 feet NW swell with 8-second period. The energy is strong. And the wind is a light cross-on offshore breeze. This is the only time where I'd say there's a chance of a few workable waves, especially for the more experienced crew. At that size, this is strictly for experts. Remember, short-period NW swell like this can close out quick at a beach break, so pick your peaks.

After that morning, it all falls apart again. We get a tease of some SW groundswell with 15-19 second periods on the 23rd and 24th, but the heights are tiny, only 2 feet. The energy is moderate, but the combination of small, long-period swell and moderate cross-onshore winds is just not going to produce anything rideable for a surfer. The wind is just too messy.

The 27th and 28th of August see another bump in NW swell, with 6 feet to 6 feet and moderate to strong energy, but the wind picks up and swings cross-shore, making it lumpy and ugly. This setup looks more interesting for kite surfing than paddle surfing, to be honest.

So, the bottom line: the only real glimmer of a chance is early on Wednesday the 19th. For the rest of this 16-day window, you’re better off finding something else to do. It’s a real shame, because Stinson can be a fun little wave, but she's not cooperating right now.

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.
