The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s headed our way for The Patch over the next couple of weeks.

We’ve got a bit of a slow start, but the good news is there’s some proper groundswell on the horizon. The water is sitting at 62°F, which is a touch warmer than normal for this time of year, so you might get away with a step down in rubber.

The first few days are small but promising. Tuesday the 8th kicks off with a clean afternoon – a 2ft SSW swell, 11 seconds, and a light WNW cross-off breeze. That’s a sneaky good session if you can get out. The energy is weak (234), but it’ll be tidy. Wednesday morning the 9th is the real standout early on: glassy conditions, a tiny 2ft SW swell but with a very long 19-second period. That’s proper groundswell energy (268) and it’ll wrap in nicely. The Patch is exposed to the SW, so this is a perfect match. The period is so long it’ll be best on the point, with long lulls and clean walls. This is the pick of the first week.

Thursday the 10th and Friday the 11th see the swell bump up a bit, but the wind swings more cross-off from the WNW. Sizes around 3ft to 3ft from the SW, with periods dropping to 16 seconds. The energy is moderate (534-686), but the conditions are clean. Lighter morning winds on Friday are better.

Now, Saturday the 12th gets a bit lumpy. Swell pushes to 6ft but it’s short-period WNW windswell at just 7 seconds. The energy is strong (702), but it’s messy and the fresh breeze is making it choppy. Not great for a paddle board – if you’ve got a kite, this might be more your scene.

We drop back down on Sunday the 13th morning with a clean 2ft SW swell, 13 seconds, and a light NW breeze. A nice little window. But the afternoon turns poor with a 5ft, 6-second windswell and 30 km/h winds. Avoid.

The middle of the week from Monday the 14th to Tuesday the 15th is a write-off for quality. Swell between 4ft and 6ft, but it’s all short-period WNW windswell (8-9 seconds) and the wind is howling at 25-30 km/h. The energy is moderate to strong (495-532), but the surf will be ugly and blown out. Not worth paddling out.

Then we get another nice little pulse. Wednesday the 16th morning: a tiny 1ft SW groundswell with a 16-second period, and a light NW cross-off breeze. Glassy, clean, and that long period will make it fun on the low tide banks. A proper micro-session.

Thursday the 17th and Friday the 18th are similar. Small SW swells (2ft to 2ft), long 16-19 second periods, and light to gentle cross-off winds. The energy is moderate (305-387). These mornings are the best of the second week. Not big, but clean and lined up.

The weekend of the 20th and 21st is poor. The wind goes onshore from the SSW and SW, killing the surface. The swell is still there (2ft, SW), but it’s choppy and messy. Skip it.

Finally, Tuesday the 22nd morning is a beauty. Flat calm, glassy conditions, and a 2ft SW swell with 16-second period. The energy is moderate (315). That’s your last real standout – a clean, empty morning.

Wednesday the 23rd sees a return to short-period WNW windswell (4ft-6ft, 7-8 seconds) and 25 km/h winds. Not for the paddle crew.

Overall, the best windows are Wednesday morning the 9th for that long-period glass and Tuesday morning the 22nd for the calm conditions. The Patch is fairly consistent, so even in the quiet spells, keep an eye on the morning light wind windows.

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.
