The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the table for the next couple of weeks at Ano Nuevo. It’s a bit of a tough stretch, so I’ll keep it real for you.
Right now, and for nearly the whole 16-day window, the pattern here is messy. We’ve got swell coming in, but the wind is just ruining it. We’re looking at a solid run of cross-shore winds that are creating chop and messing up what could be nice lines. For the first week or so, from August 17th through to the end of the month, morning sessions are the only ones worth even a glance, and even then, it’s marginal at best. The surf quality is poor, with scores hitting zero across the board, and the conditions just aren’t doing us any favors. The combined swell energy is bouncing around between 337 and 520, which is moderate energy, so there’s power in the water, but with that wind, it’s a battle.
Now, the best chance to get wet comes towards the tail end of the forecast. We’re talking Monday, August 31st, in the morning. That’s the standout of the entire run. The swell is a clean 4 ft from the SSW, which is right on the money for Ano Nuevo’s optimum direction. The period is a decent 16 seconds, so there’s good energy there – it’s proper groundswell. The wind is a light NW breeze at 6 mph, and it’s cross-shore but light enough to keep things close to glassy. The combined energy is a strong 1242 (strong energy), which is the highest in the whole period. This is the one time where the waves will actually feel like they have some punch and shape.
Keep in mind, this is a long range call, so don’t bet the farm on it, but if the forecast holds, that Monday morning will be the best we see. There’s also a small glimmer on Sunday morning, August 30th, with 4 ft from the SSW and light winds, but the energy is a touch lower at 899 (strong energy again). It's an option.
The rest? No dice. Stronger winds, lumpy conditions, and cross-chop make it a write-off. For the advanced crew only: this break is for experts, especially when it gets over 8 ft, but we don’t get there here. Given the mostly cross-shore wind and beach-and-reef setup, if you’re into the idea of kiting, you might find these conditions more interesting than paddling.
Stay patient.
Rusty.

Information about the Ano Nuevo Surf forecast
The above surf forecast table for Ano Nuevo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ano Nuevo can be found by selecting the local surf guide option on the grey menu. Our Ano Nuevo 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 (Ano Nuevo) 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 Ano Nuevo 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.
