The Lowdown

G’day, Rusty here. We’ve got a pretty mixed bag coming up at The Patch over the next couple of weeks. The water’s sitting at 17°, which is a solid 2° warmer than usual for this time of year – you’ll notice it feels like a bit of a summer holdover.

The early part of the outlook is quiet. Friday the 21st and Saturday the 22nd offer tiny, weak swell with cross-off breezes, but the energy is low (212) and the waves are barely there. It’s a slow start, but from Sunday the 23rd, things start to perk up.

Sunday morning is the first real highlight. The wind goes glassy out of the southwest, and while the swell is only 4 ft from the WNW, the period is a short 8 seconds – not a groundswell, but it’s clean and the combined energy jumps to 325. It’s a fun, small morning for the loggers and longboarders, but don’t expect much push.

The real standout is Thursday the 27th through Saturday the 29th. Thursday morning brings 5 ft of short-period NW swell (7 seconds) with light cross-off winds and clean conditions. The energy is pumping at 557 – solid moderate energy. Friday the 28th morning is even better: 6 ft from the NW, same short period, but the energy hits 813, and it’s clean with a gentle breeze. This is the pick of the first week for a rippable, punchy beach break. The short period keeps it from being too strappy, but it’s got enough juice to get you going.

Then Saturday the 29th morning – wow. The combined energy rockets to 1569, a massive jump into strong wave energy. Swell is 3 ft from the SW with a long 18-second period, and the wind is light offshore from the WNW. This is a proper groundswell, and it’s going to produce some beautifully shaped, lined-up waves. The long period means it’ll peel better than the short-period stuff, but at a beach break like The Patch, it might break a bit straight in sections. Still, for experienced surfers, this is the best session on offer – clean, powerful, and with that rare combination of light wind and long-period groundswell.

After that, the second week settles into a more consistent but less exciting groove. From Sunday the 30th through to Saturday the 5th of September, the swell stays small to moderate (2 ft to 5 ft), mostly from the SW with cross-off winds. The energy drops back into the moderate range (200-700). There’s a decent morning on Wednesday the 2nd of September with 4 ft and clean conditions, and Saturday the 5th of September morning looks good for a clean 3 ft with light wind. But nothing else matches the punch of that late August run.

For the beginner crew, the early small days are fine, but once the swell pushes over 5 ft on the 27th and 28th, it might be a bit much. The Saturday the 29th session, with its long period and clean conditions, is definitely one for the more experienced crew.

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.
