The Lowdown
Alright, surfers, Rusty here. Let's be real with you. I've scanned the charts for this stretch, and I've got to be straight: it's a tough run for the next couple of weeks. We've got one spot on the radar, Ano Nuevo, and the models are showing a whole lot of cross-shore wind and chop, which is going to make things pretty messy.
The water is sitting at 61°, which is a touch warmer than usual for this time of year, so that's a small win if you're getting in regardless.
The first week, from Tuesday the 18th through to at least Monday the 24th, is essentially a write-off. The swell is small, the wind is cross-shore, and the surf quality is just poor. Wave heights stay around 1ft to 4ft, with some longer period energy, but it's all getting chopped up by the breeze. It's one of those times where you might be better off finding something else to do. The energy is weak to moderate in this stretch, with values in the 200-500 range.
We keep waiting for something to click, but it just doesn't happen. The following week is more of the same, with poor conditions and mostly cross-shore breezes. There are a couple of moments on the 27th where the swell kicks up to 5ft, but the wind ruins it, making it lumpy and poor. By the end of the month, on the 29th and 30th, we finally see some real energy pulse in. The combined energy jumps to over 1000, which is strong, and the morning swell on the 29th is a clean 3ft from the SSW with a 16-second period. But it's still a marginal call, with the wind staying cross-shore. It’s promising, but you'd be rolling the dice. The final couple of days slide back into the mediocre zone with moderate energy and messy winds.
Honestly, there's no standout day in this whole 16-day run. The setup is just not favorable. The winds never align to give us that glassy or offshore quality we need. There’s a glimmer of hope around the 29th and 30th, where the energy is strong, but it's far out and conditions are questionable. It's a waiting game, and the long-range looks more promising than the near-term. Keep the boards waxed, but don't hold your breath.
Rusty, out.

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.
