The Lowdown
Right then, same story but in feet and Fahrenheit.
The Patch is the only spot we’re looking at. It starts off a bit bumpy and gets better as the week goes on.
Thursday afternoon, September 3rd, it’s light rain and cross-on wind. Waves around 4 ft from the west, period 9 seconds. Bumpy. Not worth the drive.
Friday morning the 4th is clean. Light cross-off wind out of the west at 6 mph, swell 3 ft but with a long 18-second period from the southwest. That’s groundswell. Combined energy is moderate at 821. That morning is a solid choice. The afternoon stays clean but the wind picks up a little.
Saturday 5th and Sunday 6th stay clean, waves around 3 ft, period dropping but still surfable. Water temp is 60°F, about average for the time of year.
Monday morning, 7th September. Glassy. Wind 3 mph from the southwest, pure mirror. Waves 4 ft at 14 seconds, energy 526. That morning is a winner.
Tuesday 8th and Wednesday 9th mornings: clean again, 4 ft, light winds. Consistent, clear, good.
Thursday 10th afternoon is the big one. Glassy, waves jump to 6 ft from the south at 10 seconds, combined energy 891. That afternoon has the most size and clean conditions. That is the standout.
Friday 11th is blown out. Onshore wind, bad. Skip it.
Saturday 12th kicks up to 5 ft in the morning, then 7 ft in the afternoon, but the period is only 7 seconds. That’s short-period, lumpy stuff. Not beginner friendly. Sunday 13th morning is glassy with 5 ft, 7 seconds. Afternoon hits 8 ft but the wind picks up and period stays short.
Monday 14th morning: glassy, 5 ft, 9 seconds. Nice clean session.
The second week gets smaller. From Tuesday 15th onward, waves drop under 4 ft. The 16th has tiny 2 ft waves but with a long period from the west, clean. Thursday 17th is glassy again, 3 ft from the west, 12 seconds. Friday 18th afternoon has 2 ft but a very long 19-second period from the southwest, clean and glassy.
Best windows are the mornings of the 7th, 8th, 9th, the afternoon of the 10th, and the morning of the 13th. Crowds can show up at The Patch, but you can dodge them.

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.
