The Lowdown
Alright folks, Rusty here. Let’s have a look at what The Patch has in store for us over the next couple of weeks.
First up, the water is sitting at a noticeably warm 61°, which is a touch warmer than normal for this time of year – a nice little bonus for the sessions ahead. We’re looking at a bit of a slow start, but things really start cooking in the second half of the run.
The first few days from Thursday the 20th through to Tuesday the 25th are pretty pedestrian. Swell is small, mostly around 1ft to 2ft from the SW, with a long period that gives it a bit of push but nothing to get excited about. The combined energy is weak to moderate (348 down to 269). Winds are clean and cross-off from the WNW, so it'll be rideable for a beginner looking to get wet, but there’s nothing here that’ll get the heart racing.
Now, things start to shift on Wednesday the 26th. The morning session sees a jump in energy with combined swell energy climbing to a solid 756 (that’s moderate to strong), and 3ft from the SSW with a 16-second period. The wind is light and cross-off – clean as a whistle. This is the first real standout of the outlook: The Patch on Wednesday morning offers good, clean conditions and a bit more grunt.
Thursday the 27th morning is another cracker. We’ve got 6ft of swell from the WNW with a short period of 7 seconds. The energy is strong at 735, and with light cross-off winds, it’ll be fun. However, at 6ft, it’s getting a bit too much for absolute beginners, but for everyone else, it’s game on.
Saturday the 29th and Sunday the 30th are the real highlight. Saturday morning delivers 7ft swell from the NW, with combined energy soaring to 1500 (very strong). That’s excellent surf, but at that size it’s for experienced surfers only. Winds are light and cross-off – perfect. Sunday morning looks similar: 7ft from the NW with energy at 1452 and light winds. If you’ve got the skill, these are the days to lock in. Just be aware that the short period (8 seconds) means it’ll be a bit chunky and top-to-bottom at a beach break, but The Patch handles it alright.
The following week (starting Monday the 1st of September) drops back down in size and energy. There’s another nice little window on Thursday the 3rd morning with glassy conditions, 2ft from the SW and a long 18-second period, energy at 363. Clean and glassy – magic for a longboard or a quiet cruiser sesh.
But the final standout is Friday the 4th. The morning is glassy with a 3ft SW swell, 18-second period, and combined energy of 1003 (strong). That’s excellent surf, clean as glass, and perfect for a range of abilities. The afternoon builds to 6ft from the WNW with an 11-second period and energy at 1921 (very strong) – that’s the biggest energy reading of the whole run. It’s going to be powerful and clean. This is the best on offer, no question.
So, if you’re picking one, Friday the 4th of September morning into afternoon is the standout. For the big-wave crew, the 29th and 30th are your jam.
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.
