St Agnes Surf Forecast and Surf Report

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

To be honest, the next week or so is looking pretty grim. We’ve got a lot of onshore and cross-onshore winds messing things up, and the swell energy, while sometimes moderate to strong, is coming with poor conditions. You’re looking at a solid stretch of days where it’s just not worth paddling out unless you’re desperate for a paddle. Friday the 11th has a 5ft west swell but with a cross-on breeze, making it choppy, and the combined energy is a moderate 417. That pretty much sets the tone for the next several days. Saturday the 12th and Sunday the 13th aren't much better, with moderate energy (267 to 509) but wafty winds and only marginal conditions at best. We’ve got a real dry spell until the middle of the following week.

Now, if you can hold out, the light at the end of the tunnel appears around the morning of Wednesday the 23rd of September. That morning is looking like a true standout. We’ve got glassy conditions – that’s a total wind shutdown – with a clean, 7ft swell from the west at 8 seconds. The combined swell energy is a moderate 534, but it’s the glass that makes this one special. That’s a solid, fun-sized wave, but at 7ft it’s pushing into that size that’s more for intermediates and up; beginners might find it a bit much. Crowds are often a factor here, so you’ll want to be sharp.

Then, the real gem might be the morning of Thursday the 25th of September. We’re looking at a 7ft west swell with a period of 9 seconds, a light offshore wind from the east at just 3 mph, and the combined energy jumps right up to a strong 1125. The forecast suggests very good surf conditions. That’s the session you circle on your calendar. Clean, offshore conditions with a powerful, long-period groundswell. For a spot like St Agnes, which is fairly exposed to the west, this is a dream setup. Just know that at 8ft in the afternoon, it gets a bit hefty for the average surfer.

A quick note on the water – for that first standout on the 23rd, it’s worth mentioning the water temp anomaly is unremarkable, so just your usual autumn wetsuit will do.

So, the takeaway? Suffer through a week of mediocrity, then pounce on the 23rd morning for clean, glassy waves. But the absolute best bet, the one to plan for, is the morning of Thursday the 25th – that’s your session for clean, strong, offshore surf.

Stay patient, and I’ll see you in the water.

Rusty.
