The Lowdown

Righto, Rusty here. Let's have a look at what the next couple of weeks is serving up at The Patch.

We’ve got a slow start here, Wednesday afternoon just isn't doing it with a weak 1ft SW swell and a cross breeze messing things up. You might as well wait it out. Things start to wake up Thursday afternoon with a bump to 4ft, but it’s a short-period W windswell and the wind is on it, so the quality is still pretty ordinary.

Friday morning is where you'll want to be. The swell picks up to a clean 3ft from the SW, and with a light WNW cross-offshore breeze, it’s looking tidy. The water temp is a pretty normal 59°F for this time of year, so not too frigid. The combined energy is moderate but solid at 742. Saturday morning is the real standout early on—3ft of SSW swell, glassy-off conditions, and that clean look will have a few happy surfers out. Sunday morning gets a touch messier with a cross-breeze, but Monday morning is a gem: glassy conditions with a 3ft SSW groundswell, long 14-second period. That long period means better-shaped waves and easy paddling, though it might close out a bit at a beach setup.

The middle of the second week gets interesting. On Wednesday the 9th, the swell jumps to 6ft from the NW, but the period is short at 8 seconds so it'll be a bit crumbly. Strong energy though, at 989. The real highlight of the whole outlook lands on Friday the 11th morning. We’ve got 5ft of WNW swell, clean cross-off wind, and the energy is humming at 655. This is a proper step up in size but still very surfable for decent conditions. Saturday the 12th morning is another glassy session with 2ft SW groundswell—small but perfect for a long, easy paddle.

Heading into the third week, there’s another solid window. Wednesday the 16th morning is clean with 4ft WNW swell, but the real standout in this later period is Thursday the 17th morning. A clean 5ft WNW swell with a 10-second period and nearly glassy conditions. This one has the best combo of size and quality. Keep in mind it’s a longer-range call so don’t lock it in just yet, but it looks promising.

Now, The Patch is fairly consistent and exposed to the SW, so there are waves most days, but don't expect the first few days to deliver. Crowds are likely on the better days, especially Saturday and Monday mornings when conditions are glassy and the swell is clean. On the bigger days, like the 6ft on the 9th and 5ft on the 11th, it'll be a bit much for beginners. For anyone else, there’s plenty to get excited about.

Stay stoked,

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.
