The Lowdown

Alright, let’s break this down. We’ve got one spot to work with for the whole 16-day stretch: The Patch. It’s a fairly consistent spot for beginners, exposed to the southwest, and it’s where any decent surf will be found. The water is 61°, which is a touch warmer than normal for late August—nice for a session.

The first real action kicks off on the morning of Friday, 28 August. There’s a glassy morning with a clean 2ft swell from the southwest and a very long period of 17 seconds. That’s groundswell, and it’s packing a moderate 416 combined energy. That’s a solid start. Saturday morning, 29 August, rolls in with 3ft of clean SW swell, a period of 18 seconds, and combined energy hitting 802—very strong. Sunday morning, 30 August, is glassy again with 3ft from the SW, 16-second period, and 705 combined energy. That’s your top window: Friday morning through Sunday morning.

A heads-up on that long period—over 15 seconds is very long. At a beach break like The Patch, it can make the waves a bit too fast and straight. But with glassy or light cross-off winds, it’ll be clean and fun for a beginner or intermediate surfer. The longer waits between sets make paddling out easier, too.

After Sunday afternoon, things drop off. The rest of the first week and into the second week sees smaller swell, mostly around 2ft, with cross-off winds and shorter periods. Combined energy falls to the 200-500 range. Surfable, but nothing to rave about.

There’s another bright spot on the morning of Friday, 4 September—2ft SW swell, 18-second period, and 744 combined energy. That’s a standout for the second week, with clean conditions. Also, the morning of Thursday, 10 September, looks glassy with 3ft SW swell and a solid 17-second period. Good call.

But the best bet is that stretch from Friday 28 August through Sunday 30 August. Crowds are sometimes around, so hit the early mornings.

Later in the second week, the wind turns onshore from the SSE. That’s going to mess things up. From 9 September, it’s mostly poor—windy and choppy.

So there you have it. The Patch is your only play. A few killer mornings, a lot of average ones, and a rough finish. Get on it when it’s glassy.

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.
