The Lowdown

G'day, I'm Rusty, and I've got a look at what's on the cards for The Patch over the next couple of weeks. It's a mixed bag, with some decent windows but plenty of ordinary days to wade through. The water temp is sitting around 60°, which is a touch warmer than normal for this time of year, so you might get away with a thinner spring suit.

The first real standout is Thursday morning, the 20th of August. The Patch is an exposed spot, and it's picking up a 5ft swell from the NW, with a short period of 7 seconds. The wind is a cross-offshore breeze from the WNW at 9 mph, which is going to keep things clean. The combined energy (596) is moderate, so there's some push. It's not a huge swell, but it's the best of the early run.

After that, things drop off pretty quickly. The swell fades right down to 1ft to 2ft over the weekend and into the start of the following week. The wind stays okay, but it's just too small to get excited about. You'll see a bit of a clean but tiny wave on Saturday morning, the 22nd, but it's pretty ordinary.

Then there's a long gap. The next chance of something half-decent doesn't roll around until Thursday, the 27th of August. The afternoon sees a 7ft swell from the WNW, period 7 seconds, with a cross-offshore breeze. The combined energy (604) is moderate, but it's a bit of a short-period swell, so it might be a bit lumpy. It's still the pick of the bunch for that week.

The end of the first week of September is looking interesting. Wednesday morning, the 2nd of September, has glassy conditions with a 4ft swell from the WNW. That's a clean, fun-sized wave with the wind off the water. The combined energy (362) is moderate, and it's a good option for the intermediate crew.

And keep an eye on Monday, the 31st of August. The morning has a 6ft swell from the NW, period 8 seconds, with a light cross-shore breeze. The combined energy (937) is strong, and it's shaping up to be a solid session if you're comfortable in the bigger stuff.

The Patch is a fairly consistent break, but it's not always pumping. The best windows are Thursday morning the 20th, Thursday afternoon the 27th, and Wednesday morning the 2nd of September. The long-range stuff is a bit more uncertain, but the glassy morning on the 2nd is a real standout.

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.
