The Lowdown

Alright folks, Rusty here. Let’s get into it.

Well, it’s a bit of a slow start for The Patch, but don’t write it off just yet. We’ve got a mixed bag of conditions over the next couple of weeks, with a few definite windows of clean, fun surf if you time it right. The water is sitting at 62°F, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit.

The first real standout comes on Monday morning, September 7th. The Patch is seeing a 3ft swell from the SSW with a lovely 14-second period, and the wind is dead calm. That’s glassy, clean conditions right there. The combined energy is moderate (467), so there’s enough push for a beginner-friendly wave. It’s a solid, small-wave session for getting wet.

The morning of Tuesday, September 8th, is also worth a look. The swell drops a touch to 3ft, but it’s still from the SSW with a 12-second period and glassy conditions. Again, clean and inviting. The energy is moderate (372).

Now, the best of the whole outlook is shaping up for Monday, September 14th, in the morning. We’ve got a 7ft pulse from the WNW, and while the period is a short 8 seconds, the wind is glassy. The combined energy jumps right up to strong (1025), so there’s some serious power. This is one for the experienced crew – 7ft plus is getting into expert territory, and with that much energy, it’ll be a handful. Very clean though.

The other big highlight is looking like Tuesday, September 22nd, in the afternoon. That’s a long way off, so treat it with a bit of caution, but the setup is promising. We’re looking at a 5ft swell from the W with an 11-second period, and the combined energy is very strong (1082). The wind is a clean cross-off, so the waves should be well-shaped. That’s an excellent wave for experienced surfers.

In between, there are a few other mornings worth noting. September 13th morning has a 6ft NW swell with a short period (8 seconds) but glassy wind, so it’s clean but lumpy. September 22nd morning also has a 5ft W swell with glassy conditions and a moderate energy (806). For the rest of the second week, you’ll find small, clean fun-sized waves in the mornings, but the afternoons get blown out by a stiff WNW breeze. The period from September 16th through the 20th is mostly small and marginal, with a lot of afternoon chop.

There’s a little window for beginners on the smaller, glassy mornings, but anything over 5ft like the 14th and 22nd is for the experts only. The Patch is fairly consistent, so it’ll fire up again before you know it.

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.
