The Lowdown

Alright, grab a coffee and listen up. This is Rusty, with a look at the upcoming swell window for The Patch.

Right off the bat, we've got a slow start. The first real action isn't until Saturday morning, the 5th, and it's a bit of a sneaky one. We're looking at a clean, waist-high swell coming in from the SSW with a solid 16-second period. That's a proper groundswell, and combined with a light cross-offshore wind, the surface is going to be glassy. The water is sitting at 61°, which is a touch warmer than you'd normally expect for this time of year, so that's a nice bonus. The total energy in the water is moderate at 669, so there's a bit of push behind it. For a beginner-friendly spot, this is a top pick; just don't expect it to be cranking. The wind is set to pick up in the afternoon, though, so make it a dawn mission.

Sunday morning, the 6th, is a solid repeat: similar size, similar direction, and a clean surface. The wind is a little stronger, but still cross-offshore, so it's still a good option. The afternoon gets blown out, so again, morning is the move.

There's a bit of a lull in the middle of the week, with the wind turning onshore or going light and variable, making for messy, less appealing conditions. The swell sticks around at around 3 ft, but the quality drops. Tuesday the 8th afternoon is a write-off, with a cross-onshore wind chopping it up.

Now, eyes forward. Thursday afternoon, the 10th, things get interesting. The swell bumps up to a solid 7 ft from the SSW, but with a shorter 10-second period. The energy is strong, hitting 1428, so there's plenty of power. The wind is a gentle cross-shore, which will keep it from being a total mess, but it's going to be a bit lumpy. That's a size that's getting into the "experts only" territory for a spot like this, so be smart.

We hit a proper flat spell from the 13th through the 17th. Tiny waves, poor conditions, and very little energy. It's a classic blank run for this area, so don't fight it.

The next real standout comes around much later. On Friday morning, the 18th, we see a new pulse of WNW swell, pushing 5 ft with a short 9-second period. The wind is a light cross-offshore, and the energy is strong at 530. That's a solid morning session. Then, Saturday morning, the 19th is the absolute gem of the outlook. The swell is a similar 4 ft, but the wind goes glassy. Dead flat, clean as a whistle. That's the day to have the place to yourself. The swell direction is WNW, which isn't the optimum SW for The Patch, but a clean, glassy wave is a clean wave.

That's the long and short of it. The early stuff is clean and fun, but the real prize is that glassy Saturday morning on the 19th. Keep an eye on the forecast, as that one is a bit further out, but it looks promising.

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.
