The Lowdown

Alright, Rusty here. Gotta be straight with you – the next week and a bit is a real mixed bag at The Patch, but we’ve got some golden moments tucked away in the second week if you’re patient.

Right now, the water temp is sitting right around average for the time of year, so nothing wild there. The first few days are a write-off for a proper session. From Monday the 31st of August right through the middle of the week, we’re looking at small, weak, and mostly messy surf. The energy is there – moderate in the 200-500 range – but it’s plagued by cross and onshore winds, leaving the surface choppy or just plain poor. Wednesday the 2nd sees the swell drop to 1 ft to 2 ft, and the period jumps all over the place, even hitting 16 seconds, but it’s still too weak to do anything with.

Things start to look a little more promising from Friday the 4th afternoon onwards. The wind swings offshore and the swell holds around 3 ft from the SW with a solid 17–18 second period. That’s proper groundswell energy, registering 751 on the energy scale. The longer period means it’ll have more push and shape, but it can be a bit tricky at a beach break like The Patch – it might wall up a bit. Still, it’s clean.

Then, here’s the standout: Saturday morning, the 5th of September. Glassy conditions, clear skies, a light breath of wind from the SSW at just 3 mph. The swell is 3 ft from the SW, with a 16-second period. The energy is strong at 607, and the wave comment says “expect very good surf conditions.” That’s the one to circle. Sunday morning the 6th will be almost as good – glassy again, 3 ft swell from the SSW, 15 second period. It’s a real treat for a couple of mornings.

After that, the surf goes a bit wonky again through the middle of the week – wind shifts, shorter period windswell, and chop – but we’ve got another true standout at the end of the run. On Monday morning, the 14th of September, the swell builds to 6 ft from the WNW with a 9-second period. That’s powerful, with 720 on the energy scale, and it’s glassy. The next morning, Tuesday the 15th, is even better: 7 ft, still glassy, WNW direction, 10-second period, and energy at 861. “Expect very good surf conditions” again. That’s expert territory at 7 ft, but for the crew who can handle it, the conditions will be epic.

So, the plan: surf Saturday the 5th and Sunday the 6th mornings for the cleanest, most user-friendly waves. Then, if you’re advanced, wait for Monday the 14th and Tuesday the 15th mornings for the biggest, glassiest swell of the forecast. The periods in between? Mostly just a waiting game.

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.
