St Agnes Surf Forecast and Surf Report

Alright, Rusty here, let’s have a look at what’s on the cards for St Agnes over the next couple of weeks.

Alright, I’ll be straight with you – the next ten days or so are looking pretty grim. We’ve got a long stretch of poor surf ahead, with only a glimmer of hope right at the very end of the forecast. From now until the 21st of August, it’s basically a write-off. The swell is small, the wind is mostly onshore or cross-onshore, and the waves are choppy and messy. There’s really nothing to get excited about until the 22nd of August.

On Saturday the 22nd, we finally get a bit of a break. It’s small, with a 1ft swell from the west, but the wind goes glassy in the morning. That’s a major positive – clean, glassy conditions even if the waves are tiny. The combined wave energy is weak (57), so it’s strictly a longboard or maybe a foamy kind of session. But hey, it’s surfable, and the peace and quiet will be nice.

After that, we’re back into a flat spell with some cross-off winds and rainy weather, but nothing with any size or power. The swell direction swings around from the south, but the heights are barely a ripple.

Now, hold on to your boards, because Thursday the 27th of August afternoon is where things get interesting. We’ve got an 8ft swell from the west-southwest, and the wind is light and cross-off from the south-southwest which will keep the faces clean. The combined wave energy is a strong 848, so there’s plenty of push. This is the standout of the whole period. The water temp is about 66°, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit. The period is a short 8 seconds, so it’s a windswell, not a groundswell, but with that size and clean wind, St Agnes will be offering up some proper waves. This is one for the intermediate to experienced crew – 8ft is getting up there, and beginners might find it a bit much.

The following day, Friday the 28th, is a total monster, but it’s ruined by a screaming 25-28 mph cross-onshore wind. We’re talking 16ft to 18ft swell from the west with a long 13-second period, and the energy is a massive 8564 to 10182. That’s huge, powerful, and dangerous. The wind is just going to shred it into a mess. Unless you’re a tow-in expert or a kite surfer, this is a day to watch from the cliffs. Absolutely not for paddle surfing.

Overall, your best bet is that Thursday afternoon the 27th. It’s clean, it’s got size, and it’s the only real window of quality in the whole 16 days. The rest is a long, flat, or windblown wait.

Catch you in the water.
Rusty.
