The Lowdown

Alright, let’s get real about the next couple of weeks.

Honestly, it’s a grim picture for the most part. We’ve got a long stretch of nothing happening. From Thursday the 6th right through the 15th, it’s pretty much flat or junk. We’re looking at tiny waves and if there is any push, the wind’s all over it. You’d be fighting cross-onshore chop for scraps. Not worth the paddle. That’s a solid 10-day drought.

There is a tiny blip on the 12th and 13th, but it’s still not enough to get excited about. There’s a little more energy, but it’s sloppy. Forget about it.

Now, here’s where it gets interesting. The morning of Sunday the 16th. That’s your standout. It’s not huge, about 5ft, but the wind is expected to go glassy. That’s the key. Finally, some clean conditions. The swell direction is from the W, which is right in the pocket for our optimum WNW. The period is 8 seconds, so it’s not a long-period groundswell, but it’ll be enough to get some fun ones. I’d be checking that morning for sure. Sure, it’s over a week out, so don’t book the day off work yet, but it’s the first real hope we’ve got.

After that, the Monday the 17th is a write-off with fresh onshore winds at 19 mph. Then look at the 19th and 20th. The swell is going to jump up – we’re looking at 8ft. That’s solid, powerful surf. But the winds are on it. On the 19th they’re strong and cross-onshore, making it lumpy and messy. The 20th looks a bit better with lighter winds, but it’s still onshore. This is pushing toward expert-only territory with that size, and honestly, the quality isn’t there. That’s a step up from the flat spell, but it’s not clean.

The water is sitting at 66°, which is a touch warmer than average for this time of year. You’ll be alright in a shorty for the most part.

So, in the end, that Sunday morning the 16th is your one true window of opportunity. It’s a river break, known as Mawgan Porth, and it’s fairly consistent when there’s swell. Be aware, it can get a bit busy sometimes. Don’t get too hyped on the bigger stuff later in the week; it’s going to need the winds to swing around to be any good. If the wind stays on it, that larger swell on the 19th and 20th might be more interesting for the kite crew than for us paddle surfers.

Keep an eye on the forecasts, though. It’s been flat, but it won’t stay like this forever.

Rusty.
