The Lowdown
G’day surfers, Rusty here. Let’s get into it.
Alright, the next couple of weeks are a mixed bag. We’ve got a slow, frustrating start. The surf is small, the wind is mostly cross-onshore, and it’s just junk. There’s a gap of a few days at the start where it’s not worth paddling out unless you’re keen for a flat paddle.
Our first real window comes on Friday the 18th. The swell is tiny, around 2 feet, but it’s glassy early with that long-period SW groundswell. That’s a clean, small morning. The energy is moderate (383), but that long period gives it a bit of push. Not big, but clean and fun on a longboard.
Then it gets messy again. The next stretch into early next week is onshore and chopped. There’s a pulse on the 22nd – around 4 feet – and the energy bumps up. Tuesday the 22nd morning looks clean with a solid WNW swell at 9 seconds. That’s a fun, manageable day. But the wind kicks up in the afternoon and ruins it.
Wednesday the 23rd is better, though. The morning has a clean offshore ENE wind with that 4-foot WNW swell at 11 seconds. A few hours of clean, lined-up surf before the sea breeze. Again, not big, but clean.
The middle of the following week is a write-off. The swell dies and the wind is onshore. It’s a frustrating stretch.
But the big one is coming on Wednesday the 30th of September. The morning is firing – solid 7-8 feet of NW swell with calm, glassy wind. This is the one. The energy is strong (1608). This is serious, powerful surf over 8 feet, so it’s strictly for the experts. Beginners stay out. This is the best morning of the whole forecast.
Thursday the 1st of October pulls back to around 6 feet but remains glassy with a strong NW swell. That’s another solid, clean day.
So, the next week is mostly small and sloppy, with two clean morning windows on the 18th and 22nd. The real standout, the one to plan for, is the big clean swell on the morning of the 30th. Don’t miss it if you’re confident.
Keep an eye on the tide for those clean windows.
Rusty out.

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.
