The Lowdown
Alright, mate, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty grim for a proper paddle. We’ve got a long stretch of nothing but onshore and cross-shore winds, and that’s going to chop up whatever swell we do get.
The first good news doesn’t even show up until August 27th, and even then, it’s marginal. For nearly two weeks, from now until then, it’s a whole lot of nothing worth getting wet for. The swell is small, the wind is messy, and the conditions are just poor.
When we finally do get a pulse of energy around Thursday the 27th, the swell builds to about 3ft to 5ft from the south, with a period around 15-16 seconds. That long-period groundswell has some push to it, with the combined energy reading a strong 1115-1211. But it’s still a cross-shore wind, so the surface is going to be lumpy and hard to enjoy. It’s not a day for the faint-hearted.
The only spot in the mix is Ano Nuevo (Big Island). It’s a beach and reef set-up, and with this long-period S swell, the reef might be the better bet, as the beach breaks could close out. It’s an inconsistent wave, so you’ll be waiting around for sets, but when they come, there’s some power behind them. The water is running at 61°F, which is a touch warmer than normal for this time of year, so at least you won't be freezing while you wait.
Honestly, there’s no standout day here. If you’re desperate, the 27th is the pick of a bad bunch, but you’d be better off waiting for the next proper groundswell to line up with some offshore winds.
Signing off, 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.

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.
