The Lowdown

Alright folks, Rusty here. It’s gonna be a quiet one for a while at The Patch, so let’s not get ahead of ourselves. The water is sitting at 59°, which is about 1° warmer than usual for this time of year – nothing to write home about, just a touch on the mild side.

We’re looking at a long dry spell to kick things off. The first decent opportunity doesn’t roll in until the morning of Friday the 4th of September. Up until then, it’s mostly small, weak, and choppy with poor to marginal conditions. Not worth paddling out for.

That Friday morning, a 3 ft swell from the SW with an 18-second period rolls in. The combined energy is moderate at 776, and with a light offshore breeze from the WNW, it’ll be clean. It’s just a marginal call, but it’s the first real chance. The afternoon sees the wind pick up a bit, but it’s still clean.

The standout window is Saturday the 5th of September. Clear skies, a light offshore wind from the WNW, and a clean 3 ft SW swell at 16 seconds. The energy is solid at 613. This is the best we’ve got – a really nice morning for a longboard or a funboard. The water is glassy, the waves are clean, and it’s accessible for beginners. The Patch is fairly consistent here, so it’s worth a look.

Sunday the 6th of September morning is also a gem. Glassy conditions with a WSW wind at just 3 mph, and a 3 ft SSW swell running at 15 seconds. Clean, smooth, and inviting. The energy is moderate at 458.

After that, the pattern gets a bit messy. Monday the 7th has another glassy morning, but the swell drops a touch. By Tuesday the 8th, the period drops way down to 8 seconds, and the swell direction shifts – it’s still surfable, but it’s not the same quality.

The second week is thinner. There’s a promising morning on Thursday the 10th of September – glassy, calm winds, and a 2 ft SW swell with a 17-second period giving strong energy at 583. That’s a long period groundswell, so expect clean lines but longer waits between sets. Perfect for a point break, but at The Patch, you’ll still get a few good ones.

After that, it’s a lot of onshore wind and short period junk. The 14th of September Monday morning goes glassy again with a 3 ft WNW swell, but the direction is off and the energy is weak. Tuesday the 15th is barely worth mentioning.

Honestly, the best of the whole 16-day run is the Saturday the 5th of September morning. If you can only pick one session, that’s it. The long period swells later in the week are clean but a bit inconsistent. Crowds are always a possibility at The Patch, so get there early for the glassy 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.
