The Lowdown
Alright folks, Rusty here. Let’s get into what’s happening at The Patch.
Honestly, the next week and a half is a bit of a grind. There’s a lot of marginal surf on the cards, but a couple of mornings in the back half of the forecast look like they’ll be worth a paddle.
We kick off this Sunday, September 13th, with tiny clean lines. The swell is a weak 2ft from the southwest, with a long period of 13 seconds. The water temperature is sitting at 63°, which is 4° warmer than normal, so it’s noticeably warmer than usual for this time of year. The wind is a moderate cross-offshore breeze, but the wave energy is weak (162) and it’s just too small to get excited about.
We’ve got a bit more size from Monday the 14th through Wednesday the 16th, with the swell jumping to 5ft on Monday and Tuesday, coming from the WNW. The period drops to a short 8-9 seconds though, and while the combined energy picks up into the moderate range (483 on Monday morning), the quality is only marginal. The wind is a bit messy, mixing cross and cross-off, and these conditions aren't doing the break any favours. The surf is just too short-period and junky to get stoked on.
Things settle down from Thursday the 17th onwards, with the swell dropping back under 3ft. The period stretches out again, hitting a very long 19 seconds by Friday the 18th, but the height is only 2ft. That’s a groundswell with a ton of energy for its size, but it’s likely to be too straight for The Patch, being a beach break.
Now, the real highlight of the whole outlook lands on Monday the 21st of September. It’s not a huge swell, but it’s the best we’ve got. The morning shows a 3ft south-west swell with a long 17-second period and combined energy climbing into a solid moderate range (528). The wind is light and variable, practically glassy, with just a slight air. This will be the cleanest the lineup gets for a while, with small, long-period lines. The Patch is fairly consistent, so there should be a few to pick from. Expect the usual sometimes crowds if you head out then.
After that, it gets messy again with onshore winds until Thursday the 24th. The next little glimmer pops up on Friday the 25th of September. The morning brings a 3ft WNW swell, period up to 11 seconds, and a clean cross-offshore breeze. Conditions look good, but the energy is only moderate (389). It’s rideable and clean, but not a standout.
The final standout of the forecast is Sunday the 27th of September. The morning is an absolute gem for conditions: a 3ft WNW swell, 9-second period, and glassy conditions with a slight air from the SSE. The combined energy is moderate (290). For a morning surf, you won’t find much better in this outlook. It won’t be huge, but it’ll be clean and fun.
Remember, anything over 5ft can be a handful for beginners, but nothing here gets above that, so all skill levels can have a crack on the better days. The long-period swells are better for points or reefs, so on those days, don't expect the world at this beach break.

Information about the The Patch Surf forecast
The above surf forecast table for The Patch provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Patch can be found by selecting the local surf guide option on the grey menu. Our The Patch 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 (The Patch) 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 The Patch 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.
The Patch is 15 km (9 miles) from the city of Corte Madera. If you plan a vacation in Marin County, look for hotels and other accommodation in Corte Madera. Corte Madera has rooms for a wide range of budgets as well as car hire and transport links.
