The Lowdown

Alright, this is Rusty, and I’ve got the full picture for Stinson Beach stretching out over the next couple of weeks.

Honestly, it’s a tough stretch to kick things off. We’re looking at a long, dry gap with pretty much nothing worth paddling out for. The first real nod at anything ridable doesn’t show up until Thursday morning, the 3rd of September. Before that, expect a whole lot of choppy, onshore, and messy conditions. The wind is mostly cross-onshore, coming from the WNW, and the swell is tiny with poor period. The energy is weak, with values hanging around 200 to 500 (combined energy of all swells directed here). It’s a rough start.

Now, let’s talk about the one standout. Thursday morning, the 3rd of September, is the best of the best here. We’ve got a glassy, clean morning with light wind from the WNW at 6 mph. The swell is a small 3 ft from the SSW, with a 14-second period. That’s a long-period groundswell, which means energy and shape, though it can tend to break a bit straight on a beach break. The combined energy is a solid 715, which is moderate to strong. This is the best window for a surfer who wants clean, glassy conditions, even if the size is modest.

The only other times that show a glimmer are Saturday morning, the 5th of September, with another glassy morning and 2 ft from the SW at 16 seconds, and Monday morning, the 7th of September, with 2 ft from the SW and 14 seconds in glassy wind. These are small, clean, and again, long-period swells. They’re worth a look if you’ve got a log and want a smooth morning.

The rest of the period is dominated by moderate to fresh cross-onshore winds, choppy water, and poor surf. The temperatures are about average for this time of year, nothing unusual.

So, bottom line: if you’re keen, set your alarm for Thursday the 3rd of September morning. That’s our pick. The rest is a write-off. It’s a quiet spell, but that’s how it goes sometimes.

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.
