The Lowdown
Alright folks, Rusty here. Let’s get into it. The swell window is looking pretty open over the next couple of weeks, but it's not all going to be firing. We've got a bit of a mixed bag lined up, so let's break it down day by day.
The first good window kicks off this Friday morning at The Patch. We're looking at clean, lined-up surf with a 3ft SW swell rolling in with a solid 18-second period. That's proper groundswell, bringing some real energy (821 combined). The wind is light and cross-offshore, so it should be glassy and super fun. You’ll want to be out there early. The water is sitting at 60.8°F, which is a touch warmer than normal for this time of year, so it’s a little more comfortable than usual. Friday afternoon stays clean but the energy backs off a touch and the tide gets a bit more critical, so the morning is your pick.
The weekend is similar. Saturday and Sunday mornings both look clean with 3ft swells from the SSW, with lighter winds. The period drops a bit, especially by Sunday down to 14 seconds, but it’s still going to be fun, clean surf. The afternoons are windier and the guidance calls it marginal, so again, make the most of the mornings.
Monday looks like a bit of a down day. The swell is still 3ft but the wind goes cross and light, which will put a bit of texture on it. It's not a write-off, but it won't be as clean as the mornings prior. Tuesday is similar, a bit more wind and shorter period, with the morning showing some cross-onshore breeze. Still surfable, but you’ll be working for it.
Now, here’s the standout of this first week. Wednesday morning, the 9th, is looking like the absolute gem. The wind drops to a glassy 3 mph from the NNW, and the swell holds at a clean 3ft with a 13-second period. That’s going to be smooth, rippable, and absolutely empty feeling. A real treat. Wednesday afternoon stays clean, just a bit more breeze.
The swell drops out from Thursday the 10th through Saturday the 12th. We have a few days of smaller, weaker surf with mostly onshore or cross-onshore winds. The energy dips hard, and the conditions just aren't there. It's a definite lull, so maybe find something else to do for a few days.
Alright, so after the flat spell, things start to pick up again on Sunday the 13th. We see a new WNW swell filling in, and a morning glass-off with a cross-off wind brings some life back. It’s not huge, 4ft, but the period is a bit shorter at 10 seconds. It’s clean, though. By the afternoon, the swell is up to 5ft but the wind is gonna be howling at 16 mph, so it’ll get bumpy.
Monday the 14th is when things get interesting. The swell is coming up, and the morning is clean with 4.5ft at a short 7-second period. That short period will likely make it a little bit sloppy, but it's surfable. The afternoon sees the swell jump to 7ft from the WNW. That's getting into proper territory, but with that short period and a moderate cross-off breeze, it might be more of a handful and better suited for the more experienced folks.
But the real standout of this second week is Tuesday morning, the 15th. We’ve got 5ft of WNW swell with a 9-second period and the wind is forecast to be absolutely glassy from the SSW at just 3 mph. This is the classic combo for perfect, clean, powerful waves. The energy reading is strong (574 combined). This is the one to circle on the calendar. It’s a week and a bit out, so treat it as promising, but keep an eye on it.
From Tuesday afternoon onward, it starts to fade away again. The swells back off, the winds get a bit messy, and we're back to small, onshore lumps for the rest of the week. The 18th and 19th do see a new long-period SW swell arriving, but it’s weak and the winds are cross-shore, leaving it pretty marginal.
So, bottom line: the early mornings this week are your friend, especially Wednesday. Next Tuesday morning looks like it could be the best of the lot, a real groundswell gem if it comes together. Stay stoked.

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.
