The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at San Carpoforo Creek.
Right off the bat, I gotta be straight with you – the next couple of weeks are gonna be a real grind. The swell is on the small side, and the wind is just about all wrong. We’ve got a persistent cross-onshore breeze from the WNW that’s gonna keep things choppy and messy. The water is sitting at a comfy 64° which is a touch warmer than normal for this time of year, but that’s about the only thing that’s gonna feel good.
For Monday the 17th and Tuesday the 18th, don’t even bother. The wave energy is moderate (429 to 579) but it’s all poor surf – that 3 ft SSW swell is getting torn apart by the wind. It’s a real shame because there’s some decent period in that swell, 15 to 16 seconds, but without clean conditions it’s just a waste.
Wednesday the 19th and Thursday the 20th are only marginally better. The wave energy is still moderate (452 to 595) but the swell stays small, around 3 ft to 3 ft, and that cross-onshore wind just won’t let up. There’s a morning here and there with a light breeze, and the “poor surf” comment might give you a glimmer of hope, but the score is still a 1 out of 10. It’s a tough call.
Now, Friday the 21st is a bit of a weird one. Swell height bumps up to 4 ft in the morning, but the period drops to 7 seconds – that’s short period, weak, windswell junk. The wind is light, which is a plus, but the quality is still marginal. Afternoon drops off to 2 ft. Not worth paddling out for.
The weekend of the 22nd and 23rd is more of the same. Small swell, 2 ft to 4 ft, and the wind is still an issue. On Sunday the 23rd morning the wind actually goes “on” from the WNW, which is offshore, and that’s a positive sign. But with a 4 ft, 8-second swell, it’s not gonna be a classic.
The whole next week, from the 24th to the 30th, is a flat spell. Swell heights are mostly under 3 ft, and the wave energy dips into the low 300s. There are a few mornings with a score of 1, but it’s all marginal. This spot is fairly consistent, so when it’s this quiet, it’s a bit of a bummer, but forecasts can change.
The real standout, if you can call it that, comes on Friday the 28th. The morning looks marginal with a 2 ft, 17-second SSW groundswell. That long period is promising for shape, and the wave energy is moderate (545). But the afternoon is a no-go – the swell jumps to 6 ft but with a 6-second period, so it’s just a messy, choppy wall of whitewater. Not for beginners, and not really for anyone but kites.
Saturday the 29th morning has a similar setup: 3 ft, 17-second SSW, with moderate energy (738). The wind is still cross-on, but it’s a light breeze, so it might be the cleanest we’ll see all period. The rest of the days into September are all poor surf, with the wave energy climbing into the 800s but the wind and swell mix just not coming together.
The best bet? Go for the morning of Saturday the 29th. Early, with the SSW swell at 3 ft and that long 17-second period, and hope the light WNW breeze doesn’t mess it up too much. It’s not a classic, but it’s the best of a bad lot.
Rusty out.

Information about the San Carpoforo Creek Surf forecast

A general guide to surfing at San Carpoforo Creek can be found by selecting the local surf guide option on the grey menu.

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 San Carpoforo Creek 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.
