The Lowdown
Right then, let’s talk about the surf. It’s quiet out there. I’m looking at a blank stretch of days, and I’m not gonna sugarcoat it – there’s nothing really worth paddling out for for a long while. The first few days of the forecast are a write-off with poor surf conditions, and it’s not until Saturday, 1st August that we finally see a small window of something worth mentioning.
The problem is the wind. For most of the time, we’ve got a cross-shore or cross-onshore breeze messing up the surface, and the swell is tiny with short, weak periods. The water is a touch warmer than normal for this time of year, sitting at 65°F.
Now, the only real glimmer of hope comes on Saturday, 1st August. The morning session at Mawgan Porth is the only thing that gets a tick. We’ve got a 2ft swell coming from the WNW with a period of 10 seconds. The combined wave energy is moderate (101). The key here is the wind: glassy conditions. That’s a rare treat, and it’ll keep the surface silky smooth. It’s a river break that’s fairly consistent and fairly exposed, so it can handle a bit of energy. The swell direction is WNW, which is pretty much bang on the optimum direction for this spot.
The crowd situation is listed as “sometimes”, so you might have a few others with the same idea. It’s a beginner-friendly break, so the small size of 2ft is perfect for that. Don’t expect anything special on the afternoon of the 1st – the wind swings cross-onshore and the energy drops slightly. After that, it’s back to poor conditions right through to the end of the outlook on 3rd August. The 2nd August has a touch more energy (126 and 220) but the wind is a cross-shore mess, so it’s not worth a look.
So, to sum it up: if you’re desperate, you’ve got one chance – Saturday, 1st August morning. Otherwise, it’s a long, quiet stretch. With the setup being a river break, and the wind being so dominant, if you’ve got a kite, this stretch might be more interesting for you than a paddle.
