The Lowdown

G’day, Rusty here. Look, I’ll be straight with you—this stretch is a bit of a mixed bag, and you’ll have to pick your moments. The Patch is our only option, and it’s fairly consistent, so there’s always a chance, but the first few days are the best of the bunch, with a gradual fade after that.

The action kicks off on Saturday morning, 1 August, with a clean 6 ft swell out of the NW, period on 8 seconds. The wind is a light cross-off, which is a nice touch, giving you some clean faces. The combined energy is 911 (moderate), so there’s some push. That’s your standout window—looks like a fun morning for anyone from beginner up, just watch the 6 ft as it’s a bit much for total beginners. The water temp is about average for this time of year, so no wetsuit worries.

By Saturday afternoon, the wind picks up to 16 mph, still cross-off from the WNW, but the swell drops to 7 ft with a period of 8 seconds and energy down to 663 (moderate). It’s a bit more windy and racy, but still clean. Sunday morning, 2 August, sees a 6 ft WNW swell with a 9-second period, light cross wind from the W, and 779 energy (moderate)—it’s marginal, with some cross-chop setting in. Sunday afternoon is a repeat of the Saturday arvo vibe, with a moderate breeze.

Monday, 3 August, the wind turns onshore from the S at 6 mph, with a 6 ft WNW swell (10-second period, 683 energy, moderate). The quality drops, and it’s a bit messy. Tuesday, 4 August, the swell fades to 4 ft, period 9 seconds, and the onshore wind from the S at 9 mph makes for poor conditions. Wednesday through Friday, 5–7 August, the surf is small and chopped, with heights around 3–5 ft and onshore winds. Not worth paddling out.

Then we get a bit of a pulse. Sunday, 9 August, morning sees a 6 ft WNW swell, period 11 seconds, with onshore wind from the S at 9 mph—marginal and messy. The afternoon is better, with a light cross-shore from the WSW and 864 energy (moderate), but still marginal. Monday, 10 August, is similar, with a 6 ft swell but onshore winds. The rest of the second week, from 11 August on, is a slow fade: 5 ft dropping to 2 ft by Thursday, 13 August, with mostly onshore or cross-onshore winds.

There’s a late shout on Saturday morning, 15 August, with a very long-period 2 ft SW groundswell (18 seconds, 435 energy, moderate). The wind is a light cross-off from the WNW, and the wave comment says “expect good surf conditions.” The small size means it’s only for the longboard or a fun cruise, and the long period will make it glassy and clean. Sunday morning, 16 August, also has a clean 3 ft SW swell (16 seconds, 408 energy, moderate), but it’s a bit more wind. These are a bit of a tease, but if you’re patient, they’re worth a look.

Overall, the standout is Saturday morning, 1 August—clean, moderate energy, and the best wind of the window. The Patch is an exposed spot, so it can get a bit of swell, but it’s also fairly consistent, so keep an eye on the forecasts.

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.
