The Lowdown

G’day, Rusty here. Let’s take a look at The Patch over the next couple of weeks.

The first few days are pretty quiet. We’ve got some small surf, but the winds are going to mess with the quality. Not really worth paddling out for much until we get a bit more push and cleaner conditions.

Wednesday morning starts things off with a tiny 1.6ft SW swell. The water is a touch warmer than normal for this time of year, around 61.7°, and it’s glassy with no wind. It’s super clean but really small. The energy is weak (268), so you’d be on a longboard just rolling around.

Thursday and Friday stay in that small range, around 2.5ft to 3ft from the SW. Energy builds a little, up to 676 on Thursday afternoon, but the winds are cross or cross-off, so it’s only just rideable. Nothing to get excited about yet.

Then Saturday rolls in with a bigger push. Swell jumps to 5.2ft in the morning and 6.6ft in the afternoon, but it’s coming from the WNW with a short, crumbly period of 6-7 seconds. This makes it messy and a bit fat. It’s probably too big and junky for the beginners seeing as it’s over 5ft, and with that period, it’s not going to be pretty. The energy is moderate (569), so there’s power, but the shape won’t be there.

Sunday morning is the first real standout. The swell drops to 5.2ft from the NW but still has a short period. However, the wind is light and cross-off, so it’ll be cleaner than Saturday. The energy is moderate (461). This is your best bet for the weekend, but the short period will still have it closing out a bit at the beach.

After that, we go through a bit of a quiet spell. Monday through Wednesday of the next week sees waves in the 3.6ft to 4.9ft range from the WNW, but the periods are short (6-8 seconds) and the winds are onshore or cross-onshore in the mornings. Afternoons are cleaner with cross-off breezes, but the surf is unremarkable.

The mid-week starts to drop right off. Thursday the 17th and Friday the 18th, we’re looking at tiny 1.3ft to 2ft swells from the SW. The energy drops away, so it’s more of a swim than a surf.

Now, about a week out, things start to look a little more promising. Saturday the 19th shows a 4.3ft WNW swell, but the period is still short. It’s a marginal call. The real gem comes on Sunday the 20th. It’s only 2ft from the SW, but the period stretches out to 18-19 seconds. This is proper long-period groundswell. And the morning is glassy, absolutely dead flat wind. This is the standout of the whole run. The energy is moderate (377-461), but the long period means it’ll have real push and shape. This is a point break or reef kind of day. The Patch is fairly consistent, so this could be the best clean session of the fortnight.

The following week starts off okay, with some 2.3ft to 2.6ft SW swells on Monday and Tuesday, but the winds are a bit onshore or cross. Then by Wednesday and Thursday, the wind really gets up—22 to 25 mph cross-off. The swell is small (2ft), and the conditions will be blown out. It's not looking like a fun paddle.

So, the long and short of it: the first week is small and junky. The standout is that Sunday the 20th morning with the glassy, long-period SW swell. The earlier weekend offers size but with bad shape. The second week is just a waiting game for that clean pulse.

Alright, stay stoked.

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.
