The Lowdown

Alright, alright, settle down. It’s Rusty here, and I gotta be honest with you, the next couple of weeks at The Patch are a bit of a mixed bag. We got a little pulse early on, but then a long, flat spell that’ll test your patience. We’re looking at a solid week to ten days of pretty weak waves in the middle of it all, so don't pencil in anything epic.

Our first real chance of a surf is Friday afternoon, the 11th. The swell bumps up to 6ft, but it’s from the WNW with a short, crumbly 7-second period. The wind is cross-off but blowing a stiff 15 mph, so it'll be a bit lumpy and challenging. It’s surfable, but it’s not the day to brag about. Water temp here at The Patch is holding about average for this time of year, so your regular suit is fine.

Saturday the 12th is the biggest of the run, pushing 6-7ft, but it's still that junky, short-period WNW windswell. With 18 mph cross-off winds, it’s going to be a bit of a grinder. There’s a lot of energy in the water, with a combined energy value of 663, but the quality just isn’t there. This looks more like a battle than a pleasure.

Now, here’s where it gets good. Sunday morning, the 13th, is your window. The swell backs off to a much cleaner 5ft from the NW, and the wind drops right out to a light 6 mph cross-off. The forecast is calling for “very good surf conditions.” The energy is moderate at 518, but that light wind will make all the difference in the world. This is the morning to be in the water. It's head-high and clean, a proper fun size.

After that, it gets messy. Monday the 14th has some size, around 4-5ft, but the periods are still short and the winds are all over the shop. The rest of that week is pretty grim, with small, short-period swell and mostly cross-shore winds. We’re looking at a long stretch of knee-to-waist high slop from the 15th through the 16th.

There is one more little glimmer on the 17th of September, a week from Thursday. The swell drops right off to a tiny 2ft but the period jumps to 21 seconds – a proper long-period groundswell. For a spot as exposed as The Patch, it might just push in a clean little waist-high wave on the sets. Winds are light, but the energy is weak at 242. It’s a long shot, but if you’re jonesing for a wave, it’s something to watch for.

The rest of the second week just fades away into tiny, inconsistent, long-period pulses. Not much to get excited about. The Patch isn’t a reliable spot, so don't be surprised if this blank run feels like the norm.

So, to sum it up: if you can only get one session in, make it Sunday morning, the 13th. It’s the clear highlight. The rest is just waiting for the ocean to wake up again.

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.
