The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Poldhu Cove. It's a bit of a mixed bag over the next couple of weeks, so we need to pick our moments.
The overall pattern shows a lot of onshore slop and choppy conditions, especially through the first week. But there are a couple of windows where the stars align for this fairly exposed SW-facing cove, and those are the ones we're chasing.
The first real chance of something rideable comes on Friday the 11th. The morning session is the pick of the early days. We've got a clean 5ft swell from the west, with a period of 9 seconds, and a light NNW breeze keeping it cross-off. The combined energy is moderate at 430. It won't be the biggest you've ever seen, but it'll be clean, and you'll get some fun ones. The afternoon goes a bit wonky as the wind swings onshore, so get your fill early.
Saturday the 12th and Sunday the 13th are a write-off with strong onshore winds, though Sunday morning does offer a 6ft cross-shore swell with a better 11-second period and a combined energy of 723. The wind is cross-shore, not clean offshore, but it’s a step up from the Saturday mess. Still, the conditions are only marginal.
We then hit a dry spell from Monday the 14th right through to Saturday the 20th. There's surf on the charts, but it's either onshore, choppy, or just too small to get excited about. The wind is a constant problem.
Now, the real standout, the one you want to circle on your calendar. It's the morning of Monday the 21st of September. After a week of frustration, this is the moment. The forecast shows a clean, glassy morning with a 4ft west-northwest swell with a solid 12-second period. The wind is a light offshore from the north-northwest, and the combined energy is a strong 727. This is a quality groundswell, and with that light offshore wind, Poldhu Cove will be clean and lined up. The swell is 4ft, so it's a friendly size for most, but the power from that 12-second period will give you some proper push. The morning is the clear winner.
The afternoon of the 21st sees the wind turn cross-on and the size bump up to 6ft, but it gets messy with a shorter period, so the morning is the only call.
The following week sees a few pulses of size, but the winds are largely cross-on or onshore. Tuesday the 22nd has a big 8ft west-northwest swell with a long 11-second period, but the cross-on wind will chop it up. That's a big, powerful swell for experts only, and even then, the conditions look challenging. The same goes for the 24th of September, with a very long 14-second period swell, but again, the onshore wind is a spoiler.
So, to sum it up: the best and most reliable surf on offer is the morning of Monday the 21st of September. Get on it. The Friday the 11th morning is a decent warm-up, but the 21st is the one. The rest of the period is a waiting game.
Rusty.

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 Poldhu Cove 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.
