The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer for the next couple of weeks.
Honestly, it's a tough stretch for the Cornwall coast. The window starts empty and stays that way for a long time. We're looking at a solid 13-day gap right off the bat with no worthwhile surf. The first real chance of anything doesn't show up until Thursday the 17th, and even then, it's a struggle.
So, the first and only real standout in this whole 16-day run is a very brief window on Thursday, September 17th. We're talking about Whitsand Bay and Tregantle. The morning session on the 17th brings a clean 3ft swell from the WSW. The wind is a clean cross-offshore from the N at 12 mph, which is a solid plus. It's a beginner plus spot and it's inconsistent, so it's not a guarantee, but for this period, this is the best you're going to get. The afternoon session is smaller, dropping to 3ft, but still with clean, cross-offshore winds from the N at 9 mph. Crowds are often an issue here, so you might have some company.
The water temperature? It's about average for this time of year, nothing unusual to report.
Before that one day, the entire forecast is a write-off. The swell is tiny, the winds are often onshore, or the period is too short to create any shape. You'll see a few days mid-week with a little bump in energy, like Wednesday the 9th with a 3ft swell, or Friday the 11th with a 4ft swell, but the wind is either cross-off or cross-on, and the reports are all "poor surf conditions" or "marginal". They just don't line up.
Then, after that small window on the 17th, it goes quiet again. The 21st of September shows a big jump in energy, with a 3ft, 16-second groundswell from the WSW, but it's being hammered by a strong 28 mph cross-shore wind. That setup is messy, and for a beach break, that long period energy will make it break too straight. That's more of a kitesurfing day than a paddle-surfing day.
So, to sum it up: wait for Thursday the 17th at Whitsand Bay. Get up early, hope the wind holds, and you might snag a few clean ones. After that, the waiting game starts again.
Rusty.
