The Lowdown

Alright folks, Rusty here. Let’s break down what The Patch is serving up for the next couple of weeks.

The Patch is the only spot on the menu, and it’s a beginner-friendly, fairly consistent break exposed to the south-west. We’ve got a bit of a slow start, but don’t get discouraged. The water is 61°, which is a touch warmer than normal for this time of year – a nice little bonus for your first paddle.

The best of the early action is on Saturday morning, September 5th. It’s only 3ft from the SSW, but with a period of 16 seconds, that’s a proper groundswell. The energy is moderate (615), and while the wind is a cross-off from the WNW at 12 mph, it’s clean enough. It’s not the day’s highlight, but it’s a start.

Sunday morning, the 6th, is a real standout. The swell is 3ft from the SSW, period 14 seconds, and the energy is still solid (595). The wind is a gentler cross-off at 9 mph, and the surf is described as very good. This is your best window for the first week – clean, consistent, and just right for a beginner.

Monday morning, the 7th, brings a glassy session with the wind shifting to a slight ESE at 3 mph. Swell is 3ft from the SSW. It’s a clean, calm window, but the energy is a bit lower (465). Tuesday morning, the 8th, is also glassy with a 3ft SSW swell and moderate energy (399). These are good, small windows, but not the top pick.

The pattern drifts into a lull after the first week. From the 9th through the 11th, the swell drops to 2ft to 3ft, with energy falling. The wind stays mostly cross-off, but the conditions are marginal. A bit of a flat spell sets in from the 13th, with a few days of barely rideable 1ft swell and poor conditions. That’s a three-day gap there with nothing worth getting wet for.

Then, on Thursday the 17th, there’s a flicker of hope. The morning session is glassy with a 4ft swell from the WNW, but the period is a short 7 seconds. The energy is low-ish (273). It’s surfable, but it’s a choppy, wind-affected swell. The afternoon picks up to 7ft from the same direction, but with a cross-shore wind and a 7-second period, it’s going to be a lumpy mess. Still, for a spot that’s been flat, it’s something.

The final stretch from the 18th to the 20th is a mixed bag. The 18th has onshore winds and 7ft of short-period WNW swell, which is a write-off. The 19th sees a drop to 5ft and a lighter cross-on wind, but the quality is still marginal. The 20th returns to a small, long-period SW groundswell, but the wind is cross-on again.

So, to wrap it up: the standout is Sunday morning, the 6th. That’s your best chance for clean, fun waves. The Monday and Tuesday mornings offer decent glassy sessions for a beginner. The long-range window on the 17th is a gamble, but if you’re desperate, it’s better than nothing. Keep an eye on the wind, and don’t bother with the flat spell in the middle.

Stay stoked.

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.
