The Lowdown
G'day, Rusty here. Let's have a look at what's on the cards for The Patch over the next couple of weeks. It's a bit of a mixed bag, to be honest. The patch is a fairly consistent beginner spot, exposed to the southwest, so it's a bit reliant on that direction. The water temperature is running at 64°, which is a solid 5° warmer than normal for this time of year—that's pretty unusual, a real treat, you'll be comfortable in just a spring suit.
Right now, we've got a little window of opportunity surf-wise. Saturday morning (September 12th) has some clean, cross-off waves at 2 ft from the SW with a nice 14-second period and moderate wave energy (410). It's not a standout, but for a beginner, it's a clean option. Saturday afternoon gets a bit too messy.
Sunday the 13th is a write-off, and so is most of Monday the 14th. However, Monday afternoon picks up with a 6 ft WNW swell at a short 8-second period, holding moderate wave energy (833). The wind is cross-off, so it'll be clean, but that short period means it's a bit junky and tricky.
The whole middle of the week, from Tuesday the 15th into Thursday the 17th, is pretty average. The swell drops, the wind turns onshore or cross-onshore, and it's just not worth paddling out for anything serious.
Now, here's a little glimmer. Friday morning, September 18th, sees a groundswell pulse from the SW at 2 ft but with a long 19-second period. The combined energy is moderate (403), and with a light cross-off breeze, it'll be glassy clean. That long period will give it shape, but it might break a little straight at this beach. Still, it's one of the better windows.
The weekend of September 20th has some size on Sunday morning and afternoon, with 6 ft to 7 ft from the WNW, but it's short-period (7 seconds) windswell. It's clean but pretty messy, hold moderate to strong energy (524-727), and it's probably more of a novelty, not a great ride.
Then we get to the absolute best on offer. Tuesday morning, September 22nd. The Patch is looking magic. We've got a clean 5 ft swell from the WNW with a decent 9-second period, combined energy is strong (658), and the wind is only a slight air, glassy cross-off. This is the standout window—perfect conditions for a beginner or intermediate, clean, fun waves.
Wednesday the 23rd sees a big spike in energy to 1304 (very strong) with a 7 ft WNW swell and a long 12-second period. That's a proper groundswell, but with onshore SSE wind, it's a bit blown out. That's expert territory if you're after a challenge, but the wind is a letdown.
The following Friday, September 25th, is another nice one. The morning is completely glassy with a 2 ft SW groundswell at 14 seconds. Total glass-off conditions—that's the second standout, just for a session on the longboard.
After that, the last weekend of September and into the 27th fades back into small, inconsistent leftovers with onshore or cross-shore winds. There are a few days with nothing worthwhile. So, to wrap it up: if you want the best waves in the 16-day period, lock in Tuesday morning, September 22nd. The glassy Friday the 25th is a nice backup. The rest is mostly small and average or blown out.
Rusty.

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.
