The Lowdown

Alright fellas, Rusty here with the lowdown on The Patch for the next couple of weeks.

Right off the bat, the first few days are pretty quiet. Monday the 20th has some knee-high swell, but the wind is a messy cross-on and the energy is weak (414). The water’s at 58°, which is a touch warmer than usual for this time of year. The first real flicker of hope comes Tuesday morning the 21st. The wind shifts to a cross-offshore, cleaning the surface up, and we get a 3ft SSW swell with a solid 14-second period. The energy is building (446). It’s small, but it’s clean and rideable for the beginners this spot is built for.

The real standout, the one you need to mark in your calendar, is Saturday the 25th and Sunday the 26th. Saturday morning, the swell is 3ft from the SW, but the period is a very long 21 seconds, and the energy is pumping (1067). The wind is a clean cross-off from the WNW. This is groundswell, and it’s going to be glassy. Sunday morning is even better for energy (1194), with a 3ft SW swell and a 19-second period. The wind is light and cross-off. These are the two best sessions of the whole forecast. The Patch is a fairly consistent spot, so a run like this is a proper gift.

A quick note on Friday the 24th. The swell is tiny at 2ft, but the period is a massive 24 seconds, and the energy is strong (830). That’s very long-period groundswell. At a beach break, it can sometimes break a bit too straight. But the cross-off wind might still give you a few clean, peeling lines if you’re patient.

Then we get a slap in the face on Monday the 27th. The morning shows a 7ft NW swell, but the period drops to a short 8 seconds, which is just windswell. The energy is huge (1477), but it’s going to be a lumpy mess. Tuesday the 28th afternoon is a hard pass for paddle surfing—the swell hits 10ft from the WNW, with a short period and strong winds (2121 energy). That’s for experts only, and honestly, it looks more like a kite-surfing day than anything else.

The second week gets a bit messy. Wednesday the 29th morning offers a solid 7ft WNW swell with a light cross-off wind, and the energy is strong (1187). That’s powerful, but for experienced surfers only. The period is short (9 seconds), so it’ll be a bit of a wrestle. After that, the swell fades and the conditions get more marginal, with cross-shore winds and lower energy through the end of July and into August. The 3rd and 4th of August bring some mid-period swell, but it’s inconsistent and the wind isn’t cooperating.

So, to wrap it up: the best of the best is Saturday the 25th and Sunday the 26th. Get out there for the morning glass. The rest of the time, pick your moments carefully.

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.
