The Lowdown
G'day, Rusty here. Look, the next couple of weeks at The Patch are a bit of a mixed bag. We've got a solid run of clean, glassy conditions coming up, but the swell is going to be inconsistent and on the small side for a good chunk of it. The water temp is sitting at 60°, which is a full 2° warmer than usual for this time of year, so it's a bit of a treat.
We kick things off on Sunday morning, the 30th of August. There's a 3ft swell from the SW, but a light cross breeze is kicking up a few ripples. The combined energy is moderate at 652. It's rideable, but nothing to write home about. The afternoon drops to 3ft, and the wind's a bit stronger.
Monday the 31st is pretty average with a dropping swell, and Tuesday the 1st of September is even worse – tiny waves and poor conditions. Wednesday the 2nd is still small, but we start to see a slight improvement. The real turnaround starts on Thursday the 3rd of September. The morning has a 2ft SW swell, but the afternoon is where it gets interesting. The wind swings light cross-offshore, and the swell bumps up to 2ft from the SW with a long 15-second period. The energy is 348, and it's clean. It's a small wave, but it's a sign of better things.
Friday the 4th of September is the first real standout. The morning looks fantastic. We've got a 3ft SW swell with an 18-second period, meaning it's a proper groundswell. The wind is light and cross-offshore, and the energy is a solid 697. The conditions are clean, and it's a great day for a beginner-friendly wave. The afternoon holds up too, with a 3ft swell, though the wind picks up a bit.
Saturday the 5th has a similar size swell but with a cross-on breeze, so it's not as clean. Sunday the 6th is back to clean cross-off winds, with a 3ft SSW swell. Monday the 7th is a cracker. The wind goes completely glassy, with a 3ft SSW swell. It's a beautiful morning for a paddle, even if it's a bit small.
Now, the real standout for the entire forecast is that Wednesday morning, the 9th of September. The wind is glassy again, and the swell has built to 5ft from the S, with a moderate 11-second period. The energy is 768, and it's clean, clean, clean. That's the one to circle on the calendar. The rest of that week and into the next is solid, with clean cross-off winds and consistent 3ft SW swells.
Then we get to the second week and things get big. Saturday the 12th of September is for the experienced crew only. The morning is glassy, but the swell is a solid 7ft from the WNW at a short 8-second period. The energy is a massive 1079. That's a lot of water moving around. The afternoon sees it push to 8ft. It's going to be a heavy, powerful, but short-period swell. For a beach break like The Patch, it's going to be a bit of a washing machine.
Sunday the 13th of September looks like a write-off. The morning is onshore, and the afternoon sees a monster 10ft WNW swell with extremely high energy at 1617. The finder notes that the swell is predicted to be too big for this break. It's a definite no-go for paddling, and honestly, it might be more interesting for the kite surfers than anyone else. Monday the 14th finally drops back down to a more manageable 6ft, but the wind is still onshore.
So, the pick of the lot is that Wednesday morning, the 9th of September. Glassy conditions, a solid 5ft south swell, and clean lines. Friday the 4th of September morning is a close second for the smaller, long-period groundswell. The big weekend on the 12th is for experts only. Stay safe out there.
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.
