The Lowdown

Alright folks, Rusty here. Let's look at what we've got going on.

Overall, it's a pretty quiet run ahead. We've got Stinson Beach on the menu, and honestly, for the next week and a half, you're mostly fighting cross-onshore winds and choppy conditions. There’s a little window of hope, but you gotta be patient. The water's sitting at 61°, which is a touch warmer than normal for this time of year, so that’s a small win.

Thursday the 3rd and Friday the 4th are write-offs with poor surf conditions and cross-onshore wind. Stinson is a beginner-friendly spot, but this isn't really doing anyone any favors.

Saturday the 5th and Sunday the 6th are more of the same: cross-onshore breeze, small swell around 3 ft to 4 ft from the SSW, and choppy surfaces. Not worth the paddle.

Monday morning the 7th is your standout. It's not big, with the swell sitting at 3 ft from the SSW, but the wind goes glassy. That's the word we want to hear. For a few hours, the conditions will be clean and smooth at Stinson Beach. The combined energy is moderate at 462. If you can, get out there early because the afternoon turns choppy again.

From Tuesday the 8th through Thursday the 10th, it's mostly light cross-onshore wind and marginal surf. The waves are small, around 2 ft to 3 ft, with moderate energy (between 385 and 564). It’s not going to be great.

Now, jump ahead to Friday the 11th of September. This one’s for the experienced crew only. The swell jumps up to 8 ft from the SW with a moderate period of 12 seconds, and the combined energy is strong at 1660. That’s a solid wall of water. The morning has light cross-onshore wind, so it might be manageable for experts, but the afternoon gets a moderate cross-shore breeze, which will make it ugly. This is not for beginners — over 8 ft it’s expert territory.

After that, Saturday the 12th through Sunday the 13th drops back to smaller, choppier surf, and then the last few days from Monday the 15th to Thursday the 17th it just flat-lines into tiny, weak swell below 2 ft. There’s a sniff of a longer-period groundswell on Friday the 18th of September with a 20-second period and 2 ft to 3 ft from the SW, but it’s only marginal and winds are onshore.

So bottom line: the Monday morning the 7th is your best bet for clean, small waves for the beginners, and the Friday the 11th is the only real size day, but that's for the experts only, if they can handle the chop. The rest? It's a waiting game.

Stay wet, stay sharp.
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.
