The Lowdown

G’day, I’m Rusty. Let’s have a look at what’s on the cards for The Patch over the next couple of weeks.

Right off the bat, we’ve got a bit of a slow start, but there’s a decent run of surfable conditions kicking off on Friday the 4th of September. The water’s sitting at a pleasant 61°, which is a touch warmer than what we’d normally expect for this time of year – nothing too wild, but nice to feel.

Overall, the pattern is small, clean, and consistent with a long-period SW groundswell. The combined energy sits in the moderate range (around 755 to 445), so there’s enough push for a fun session on a longboard or a mini-mal. The standout here is the Saturday morning session on the 5th and again on Wednesday morning, the 9th of September. That Wednesday morning is looking particularly special – glassy conditions with a light NW breeze, 2ft of SW swell at a very long 19 seconds. That’s proper groundswell energy (511) and the glassy surface will make The Patch feel like butter. Not a big wave, but if you’ve got a log, you’ll be grinning.

The Patch is fairly consistent, and with the wind mostly cross-off or glassy through the first week, it’s a good bet for beginners and cruisers. Crowds can pop up sometimes, but with these smaller sizes, it shouldn’t be too hectic.

Now, let’s move through the period. Friday afternoon the 4th kicks off with 3ft SW swell, 17 seconds, and a clean cross-off breeze. It’s marginal with tide, but it’s a start. Saturday morning the 5th is the pick of the early days – 3ft SSW at 16 seconds, clean, and the wind is light. Sunday morning the 6th is similar but with a touch more size at 3ft. The afternoons get a bit breezy, so aim for the mornings.

Monday the 7th and Tuesday the 8th are still rideable but with a lighter wind and some cross-shore chop. The real gem comes Wednesday the 9th – glassy, 2ft at 19 seconds – that’s a dreamy morning. Thursday the 10th morning is clean again with 2ft, but the afternoon sees a jump in size to 7ft from the S with a short 8-second period. Combined energy jumps to 1095, but that short period and onshore wind will make it a bit messy. That’s more of a challenge than a pleasure.

Friday the 11th is back to the good stuff: 3ft SW at 16 seconds, clean or glassy. The weekend of the 12th and 13th drops off significantly – energy falls to around 292, and the waves get smaller and more crumbly. Not worth paddling out for.

Then we hit a quiet patch. From Monday the 14th through to Wednesday the 16th, there’s very little to get excited about – tiny 1ft to 2ft swells, short periods, and mostly poor conditions. A gap of about three days with no real surf to speak of.

But hold tight – the real standout of the entire forecast is the morning of Friday the 18th of September. That’s over a week away, so keep an eye on it, but it’s looking promising. An 8ft WNW swell, 8 seconds, with a light NW cross-off breeze and clean conditions. Combined energy is 1123 – that’s strong. The Patch is exposed and the size is getting up there; this is for experienced surfers only. If you’re a beginner, give this one a miss. The afternoon drops off to 8ft with a stronger breeze, but the morning is the window.

The following Saturday the 19th fades back to small, clean leftovers.

So, to wrap it up: the best of the next two weeks are the glassy 2ft morning on Wednesday the 9th, and the bigger, more powerful 8ft morning on Friday the 18th. The rest is small but clean for a log, with a few days in the middle where you’re better off doing something else.

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.
