The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.

Well, to be straight with you, it’s a tough outlook. The only real shot we’ve got is over at Portreath Harbour Wall. But I’ll be honest, it’s a real mixed bag and nothing is going to be easy. Don’t go in expecting a classic.

The water temp is sitting at 64°, which is a touch warmer than normal for this time of year, so you might get away with a slightly thinner suit.

The first chance to get wet is on Saturday, September 5th. Saturday morning is the pick of the entire 16-day window. We’ve got a solid 5ft swell from the WNW, with a decent 12-second period pushing in. The combined energy is moderate (730), so there’s a bit of push behind it. The wind is light and offshore from the WNW, so the face should be clean. That’s a real positive. The only buzzkill is that the tide or conditions might be a bit tricky, but if you’re keen, that’s your window. It’s an advanced reef break, so it’s not for learners, and the swell is getting up there, so be careful. Saturday afternoon goes cross-shore, and the energy drops off a touch.

After that, it’s a long, bleak stretch. From Sunday morning all the way through to Saturday, September 19th, the conditions are just poor. The wind is either onshore, cross-onshore, or just too strong. A big swell rolls in on Monday, September 7th, with 8ft from the W and a 13-second period, and the energy is very strong (1783), but the wind is a nasty cross-onshore, making it a choppy mess. That’s more of a kitesurfing setup than a clean paddle session. The swell size over 8ft on a few days is only for experts, but the wind just ruins it anyway.

After a long gap of nothing much, we finally get a slight glimmer on Sunday, September 20th. The morning shows a small 2ft WNW swell with a clean, light offshore wind from the ENE. The energy is weak (77), but it’s clean. The waves are described as surfable but very ordinary. For a reef break, the long period stuff can sometimes make it too straight, but with a period of 9 seconds, it’s manageable. The afternoon goes cross-onshore again, so it’s a one-session kind of day.

So, to sum it up: Saturday the 5th morning is the standout, but it’s not a classic. Sunday the 20th morning is a last-ditch option if you’re desperate. The rest of the window is a write-off.

Rusty.
