The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Stinson Beach over the next couple of weeks.
Straight up, it’s a tough outlook for the next week and a half. The first surf worth mentioning doesn’t show up until Saturday the 8th, and even then it’s only marginal. The pattern is dominated by poor conditions – funky winds, messy waves, and not much to get excited about. There’s a real dry spell in the middle too, with several days of just nothing worthwhile.
The water temp at Stinson Beach is sitting at 60°, which is a touch warmer than normal for this time of year, so that’s a small comfort if you’re paddling out.
The first hint of anything is Saturday the 8th. Morning sees a 5 ft swell from the WNW, but the wind is cross-on from the W at 6 mph, so it’s light and choppy. The wave energy is moderate (506). It’s a marginal call at best. The afternoon is worse with a bigger 5 ft swell but the wind picks up to 12 mph cross-on, making it choppy and poor.
Sunday the 9th has a similar story. Morning swell is 6 ft from the WNW, with a light cross-on breeze from the SSW. The energy is getting stronger (887), but the wind keeps it messy. Afternoon is onshore and not much better.
The whole week after that is a washout – mostly poor surf, with onshore or cross-on winds, until we get to the second week. The standout, if you can call it that, is Monday the 17th. That morning looks glassy. There’s a 3 ft swell from the W with a period of 13 seconds, and the wind is glassy – slight air, no chop. The energy is moderate (534). This is the only window with clean, glassy conditions, and the south-facing exposure of Stinson Beach will be catching that long-period west swell. It’s a small wave, so it’s ideal for beginners and longboards, but the tide and consistency will be key. The afternoon turns ugly again with cross-on winds.
So, the best on offer is the morning of Monday the 17th. It’s not going to be big, but it’ll be the cleanest surf of the whole forecast. Hang in there.
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.
