The Lowdown

Alright, let's talk about Stinson Beach. I gotta be honest, this stretch is looking pretty flat and uninspiring for the most part. The water is sitting at a warm 63°, which is much warmer than normal for this time of year, so you might be tempted to just go for a swim.

The whole outlook is a long, quiet slog. There’s a whole lot of "poor surf conditions" strung together, with a mix of onshore and cross-onshore winds chopping things up. The swell energy is mostly weak to moderate – the best we see in the entire period is a combined energy of 538 (moderate) on the morning of Sunday the 16th, but even then, the surf is only marginal. The swell is mostly from the SW and WNW, with periods that are all over the place, from short 8-second stuff to some very long 19-second groundswell, but unfortunately, the size is tiny.

From Tuesday the 11th right through to Friday the 21st of August, there’s hardly a sniff of a decent wave. The wind is no friend to us, mostly blowing onshore or cross-onshore, leaving the surface chopped and messy. It’s a real desert out there.

The only glimmer of hope, and I mean a tiny glimmer, comes on Saturday the 22nd of August in the morning. We’ve got a glassy, clean surface with a light wind from the WSW, and a WNW swell of 2 ft at 10 seconds. The combined energy is a weak 233. It’s surfable, but very ordinary. The break is a beginner-friendly beach, and it’s fairly consistent, but it’s rarely going to turn on. For a bit of a paddle and a few small, clean waves, it’s your best bet in the whole 16 days. After that, it’s back to the same old story.

Honestly, this is a tough one. The long-range stuff out past the 22nd looks promising on paper with some long-period SW swells, but the size is so small and the wind is likely to mess it up. If you’re desperate for a session, that Saturday morning window is the one to keep an eye on, but don’t get your hopes up.

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.
