St Agnes Surf Forecast and Surf Report

Alright, Rusty here again. Gotta be straight with you – this stretch for St Agnes is a bit of a heartbreaker. We’ve got a long, frustrating wait ahead with a whole lot of messy onshore wind and pretty average conditions. But there is a little light at the end of the tunnel, so hang in there.

The outlook starts now and runs all the way through the 16-day window. The first bit of surf that’s even worth talking about doesn't show up until Monday, August 24th. From now until then, it’s a long slog of close to two weeks of choppy, lumpy, or just plain poor conditions. The winds are a problem, mostly cross-on or onshore, and the swell isn’t clean enough to do anything with.

Let’s look at the rest. Through the end of August and into early September, the wind stays mostly cross-on from the west or northwest, with a fresh breeze. Swell heights bobble around from 2ft to 5ft, but the wave energy is weak to moderate at best, with a combined energy reading between 62 and 451. The real bummer is that it’s just not clean. A lot of the time the wave comment is "poor surf conditions" or "fresh cross-onshore and lumpy". There’s one half-decent window on Wednesday, August 19th, where we see a bit of WNW swell at 5ft with 9-second period and moderate energy (360), but it’s cross-on and choppy, so it’s still not a goer.

Now for the one true standout. Monday, August 24th is your date. This is the only real glimmer of hope in the whole run. We’ve got a solid 7ft swell rolling in from the west with an 8-second period, and the combined energy jumps right up to 532 to 544, which is strong and will have some punch. But the real magic is the wind. It’s a light breeze from the southeast – that’s offshore. The wave comment for both the morning and afternoon is "clean" and "expect good surf conditions". At St Agnes (Cornwall), that offshore wind will make the waves clean and lined up. The water is 66°F, about 4°F warmer than average for the time of year, so a touch warmer than you’d expect. This is the session to point for. The crowd at St Agnes is often there, so expect company for this one.

After that, it’s back to poor form from August 25th onward. The swell drops, the wind turns onshore again, and we’re looking at cross-on chop all over again. A few smaller pulses of swell come through on the 26th and 27th, but with fresh breezes and lumpy conditions, it’s not worth the drive.

So, to sum it up: a long, painful wait, but the morning of August 24th is your absolute best bet. Mark it on the calendar.

Rusty.
