The Lowdown

Alright mate, Rusty here. Let’s have a look at what’s in store for us at The Patch over the next couple of weeks.

Honestly, for the first few days, it’s a bit of a waiting game. We’ve got some tiny, weak swell rolling in, but nothing really worth getting wet for until we get towards the end of the first week. The water is sitting at a warm 62°, which is a fair bit toastier than usual for this time of year, so at least the wait will be comfortable.

Friday the 21st and Saturday the 22nd are pretty forgettable, with small 1ft to 2ft SW swells and moderate cross-off winds. The combined energy is weak to moderate (226 to 171). Not much to write home about. Sunday the 23rd stays small with a touch of cross-onshore wind, making things a bit bumpy.

Monday the 24th through Thursday the 27th is a stretch of persistent but very ordinary conditions. Swells stay under 3ft for most mornings with clean conditions from a light WNW cross-off breeze, but the energy just isn’t there. The scores are low across the board, and the wave comment is consistently “marginal.” Thursday afternoon sees a jump to 5ft, but the period drops to a short 7 seconds, so it’s going to be a bit of a choppy mess.

Now, Friday the 28th is where it finally gets interesting. That morning brings a solid 7ft swell from the WNW with an 8-second period. The wind is clean cross-off and light at 9 mph. The combined energy is a solid 1255, so there’s plenty of push. This is the pick of the whole outlook, but heads up – at 7ft this is getting solid and really only for the experienced crew. It’s going to be a standout session for those who can handle it.

Saturday the 29th and Sunday the 30th back off a touch, but Sunday morning pumps up again to 7ft from the WNW. By Sunday afternoon it’s pushing 8ft with a fresh 19 mph cross-off, so the energy is still strong (1000). Monday the 1st of September (that’s 11 days away) shows the biggest number of the run – a 8ft NW swell with 9-second period and massive energy at 1590. This is a long-range call, so don’t lock it in just yet, but it looks promising for the more advanced surfer.

After that, the rest of the first week of September drops back into the 3ft to 5ft range, mostly cross-shore or light onshore winds, with moderate energy. Nothing that screams “drop everything and go.”

So, to wrap it up: The standout moment is Friday 28th morning – 7ft clean WNW swell, light offshore wind, perfect for the more seasoned surfer. Sunday 30th morning is another solid shout. The long-range Monday 1st September is a promising one to keep an eye on. For the rest, it’s a steady but unspectacular run of small, average conditions.

Stay patient, and grab the good ones when they come.

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.
