The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer at The Patch for the next couple of weeks.

First up, the water temp is sitting pretty average for this time of year, so no need to worry about a weird chill or a warm flush.

The week ahead kicks off pretty flat and uninspiring. Friday the 7th and Saturday the 8th of August are a write-off – tiny little swell around 1ft to 2ft from the SW, crossed up and messy with light onshore or cross-shore breezes. The energy is weak (183 to 332), and there’s just nothing to get excited about. You’d be better off doing something else.

Then Sunday the 9th of August is where it gets interesting. The Patch wakes up with a solid 6ft swell from the WNW, but the period is a short 10 seconds, so it’s a bit of a windswell bump rather than clean groundswell. The morning is the real standout here – light offshore breeze, clean conditions, and the combined energy is pumping (694). That’s the best morning of the whole outlook. The afternoon picks up a stronger breeze but stays clean. It’s still a decent wave, but the morning is where it’s at.

From Monday the 10th through Wednesday the 12th, the surf drops back to 4ft to 5ft but the wind turns onshore or cross-onshore, and the quality goes out the window. The energy is moderate (366 to 533), but the conditions are poor. Not worth the paddle.

Thursday 13th and Friday 14th of August drop back to tiny 2ft to 2ft SW swell. A bit of energy (286 to 331) but the waves are gutless and the wind is messy. Still a no-go.

Saturday the 15th of August sees a slight bump back up to 3ft from the SW with a long 16-second period. That’s some proper groundswell energy (507), and the morning has light cross-shore winds. It’s small, but the period means it’ll be lined up and clean. Best of the second week, but still small. The afternoon is clean with a cross-off breeze.

Sunday the 16th and Monday the 17th of August stay small (3ft to 3ft) with the same long-period SW groundswell. The mornings are clean with light winds, but the afternoons get a bit choppy. These are the best of a quiet period – small but clean and fun for a longboard or a mid-length.

Tuesday the 18th of August morning is clean with 2ft SW swell and a 14-second period. The energy is moderate (353) and the conditions are clean. A nice little session if you’re keen.

On Wednesday the 19th and Thursday the 20th of August, the swell holds around 2ft to 5ft. Thursday afternoon is the standout of this little run – a 5ft WNW swell with a 12-second period, cross-off breeze, and the energy is massive (996). That’s a lot of power for a small-ish wave. Best for experienced surfers as it’s just over 5ft. The morning is also clean with 4ft from the WNW.

Friday the 21st of August drops back to 2ft to 3ft, and the wind turns a bit messy again. Not a highlight.

Saturday the 22nd of August is small again, 2ft from the SW, light cross-on wind. Another day to sleep in.

Overall, the real standout is Sunday morning the 9th of August – 6ft WNW swell, light offshore wind, clean conditions, and good energy. That’s the one to circle. The second best is Thursday afternoon the 20th of August – a bit smaller but with a long period and a lot of power, clean and cross-off. The Patch is fairly consistent, so when it’s poor, it doesn’t stay that way long.

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.
