The Lowdown

Alright, Rusty here again, but this time in feet and miles for the imperial crew.

Water temp is about 60°, a touch warmer than usual for this time of year – not bad.

Let’s break it down. The Patch kicks off Monday, 27 July with a 3ft SW groundswell, 18-second period – that’s long, proper groundswell. The combined energy is 737 (moderate). Wind is cross-off from the WNW at 12 mph, so it’s clean. The Patch is a beginner spot, but that long period can make it a bit straight at a beach break. Still, it’s a clean start.

Tuesday, 28 July is much the same – 4ft, 18 seconds, cross-off wind. Energy builds to 914 in the morning, then 1198 in the afternoon (moderate to strong). Consistent, but not a standout.

Wednesday, 29 July morning is the best of the first week. Swell drops to 3ft, but the period is still 16 seconds, and the wind drops to a light 6 mph – glassy, clean. Energy is strong at 1237. The afternoon wind picks up to 16 mph, so hit it early.

Thursday, 30 July morning has a smaller 3ft SSW swell, still clean with a gentle breeze, energy at 839. The afternoon switches to a 7ft short-period WNW swell at 8 seconds, cross-off wind – lumpy and walled up, but surfable.

The real standout is Friday, 31 July morning. We’ve got a 7ft NW swell, short period of 8 seconds, but the wind is a light 6 mph cross-off. Energy is pumping at 1165 (strong). This is expert territory – over 7ft is big for most. The conditions are clean, and the energy is there. This is the call.

Saturday, 01 August morning drops to 5ft, short period, gentle breeze – clean but not as punchy. The afternoon gets a fresh 19 mph wind, so it’s blown out.

Sunday, 02 August morning is another solid option – 7ft WNW swell, 9-second period, light 6 mph wind. Energy is 923 (moderate). The afternoon pushes to 8ft, but wind gets to 12 mph, still cross-off – big and clean, but only for the experienced.

From Monday, 03 August onward, the wind shifts onshore (S and SSW), and the swell drops. Energy falls into the 300s and 400s (weak), and the wind is onshore, making for choppy, poor conditions. There’s a long gap of poor to marginal surf from 03 August through to 11 August. The last few days have some energy but the wind is wrong.

If you’re a kiter, the afternoons with stronger cross-off winds and some swell could be fun, but for paddle surfing, it’s a no-go after the first week.

So, the standout is Friday, 31 July morning – big, clean, powerful. The backup is Wednesday, 29 July morning for a glassy, long-period runner. After that, you’re waiting for a change.

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.
