The Lowdown

Alright folks, it’s Rusty here. Let’s have a look at what’s coming up for The Patch.

We’re in for a bit of a mixed bag over the next two weeks. The swell hangs around, but the quality is gonna be a real seesaw. The real standout window is Friday the 4th of September, especially the morning, with clean conditions and a solid 3ft of SW groundswell at a long 18-second period. The energy’s got some punch to it (742), and that light offshore cross-off breeze from the WNW will have the waves looking like glass. This is the pick of the early run, no doubt.

The water’s sitting at 60°, which is about where you’d expect for this time of year.

From Thursday the 3rd, we’ve got a bit of a slow start. Thursday morning is poor with a southerly wind messing things up, but the afternoon tries to get going with a weak 4ft W swell, though the period is a short 9 seconds and the wind is cross, so it’s a bit of a struggle.

Friday the 4th afternoon is still clean, but the swell has dropped a touch. Saturday the 5th through to Monday the 7th offer similar small surf, around 3ft to 3ft, mostly from the SSW. The morning of Monday the 7th is a highlight with glassy conditions, but it’s still small. Tuesday the 8th and Wednesday the 9th are similar, with light winds and cleanish waves, but nothing to get too excited about.

Now, looking ahead to Friday the 11th of September, we get a spike in size. The morning shows a solid 8ft of SW swell, but it’s a short period of 12 seconds, and the wind is light cross, so it’s more of a challenge than a treat. The afternoon drops to 6ft from the SW, still with a short period, and a stronger cross-off wind from the NW. This is expert territory – the size is there, but the quality is marginal.

The next promising window is the morning of Saturday the 12th and especially Sunday the 13th. Saturday morning has 4ft from the W with a short period, but the wind is clean and cross-off. Sunday the 13th morning is the real standout for the second week, with 5ft of WNW groundswell at 11 seconds, and a light cross-off breeze. The energy is moderate (580) and the conditions should be very clean. This is a solid session if you’re keen.

After that, the energy drops off significantly from Monday the 14th, with small, weak swell and poor conditions through to the end of the forecast. Thursday the 17th and Friday the 18th show a bit of a pulse from the SW with long periods (15-20 seconds), but the winds are onshore or cross-onshore, so it’s likely to be a bumpy mess and not worth the paddle.

So, if you’re watching the calendar, Friday the 4th of September morning is the clear winner, with Sunday the 13th of September morning as a solid, promising runner-up. The rest is mostly small, clean, and average, or big and messy.

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.
