The Lowdown

Alright, grab a coffee and let’s look at what’s coming.

Truth is, Stinson Beach is going to be a tough slog for a while. There’s a long gap with barely anything worth paddling out for. The first half-decent chance isn’t until Tuesday the 18th, and even that’s messy. Sunday and Monday are total washouts – tiny, choppy junk with the wind on it.

Tuesday the 18th morning, we get a pulse of swell around 6ft out of the WNW, but the period is short and fat at 8 seconds. The combined energy is moderate (653), but the wind is cross-onshore, so it’s bumpy. It’s beginner-friendly size, but the chop will make you work. Not a standout, but it’s something.

The best we’ve got in this whole 16-day window – and I’m being real with you – is Thursday the 27th morning. Swell sits around 6ft from the WNW, period stretches to 9 seconds which gives it a bit more grunt. Combined energy is strong (573). The wind is light and cross-onshore, so you’ll see small ripples but not whitewash. For this spot, that’s the cleanest you’ll get in this forecast. That afternoon, energy jumps to 717, but the wind picks up and ruins it, so the morning is your window.

Friday the 28th morning is also worth a look – 5ft WNW groundswell, period 9 seconds, energy strong at 748. Light cross-onshore again, so it’ll be cleaner than most. Not perfect, but compared to the rest, it’s a decent session.

Everything else is either too small, too onshore, or both. Water temp is about average for this time of year, nothing unusual. Stinson is a beach break, so the wind just tears it apart. There is a moment late on the 31st Monday morning where the wind goes glassy, but the swell is tiny – 2ft from the SW with hardly any energy (246). Fine for a log if you’re keen.

Crowds are possible on the better days, so expect company if you hit that Thursday morning.

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.
