St Agnes Surf Forecast and Surf Report

Alright, folks, Rusty here. Let's have a look at the 16-day picture for this stretch of coast, focusing on one familiar spot: St Agnes.

Right off the bat, I gotta be straight with you—it's a grim start. We're looking at a stretch of days where the surf is practically non-existent or just plain ugly. For the first week and a half, it's a washout. From the first of August all the way through to the morning of the 12th, don't expect anything worth paddling out for. There's nothing to get excited about. The winds are messy, and the swell is tiny or blown out. We're talking a solid 11-day gap where you're better off doing something else.

Now, the first real flicker of life shows up on Monday morning, the 12th of August. We see a pulse of swell pushing up to 4ft from the WSW, with a period of 8 seconds and moderate energy in the water (283). The morning offers a light cross-onshore breeze, but the surf is still rated as marginal due to questionable conditions. It’s a glimmer, but not much more.

Then, on the morning of Wednesday, the 13th of August, we get something that might make you take notice. It's not huge, with swell at 4ft from the WSW, but the wind drops right out. We're calling it glassy. That's a major positive. For that one brief window, if you can get out there, the waves should be clean and smooth. The energy is moderate (183), and with the wind like that, it's your best shot in this entire outlook. It's just one session, though, so make it count.

After that morning, the winds pick up again and the quality drops straight back into that cross-onshore chop.

Looking way ahead to the final Sunday and Monday of the outlook, the 16th and 17th, there's a bigger pulse of swell forecast—8ft to 8ft from the WNW. That's getting into serious territory, probably only for the experienced crew. The combined energy is strong (608 and 730). But the conditions are still messy, with cross-onshore and cross-shore winds. That size and wind combo looks more like a kite-surfing setup than a clean paddle session.

Water temp at St Agnes for that first mentionable window sits at 65°, which is a touch warmer than normal for this time of year.

Overall, it's a tough 16 days. The Wednesday the 13th morning glass-off is the one to aim for; everything else is a fight against the wind or a complete flat spell.

Rusty.
