St Agnes Surf Forecast and Surf Report

Alright, let’s talk about what’s coming up for St Agnes over the next couple weeks. Truth is, it’s a tough run. There ain’t any real barnburners here, and the wind’s gonna be a pain in the neck most days. The best I can do is point you to a couple of windows where it’s less of a mess.

Starting Saturday the 29th of August, we’ve got a solid push of swell – 10ft to 12ft from the SW and WSW, with period around 8 to 9 seconds. That’s a decent amount of water moving, with combined energy at 984 then jumping to 2296 on Saturday afternoon. But the wind is all over it. Saturday morning it’s a cross-off from the SW at 22 mph, and by the afternoon it’s a strong cross-onshore from the WNW at 25 mph. That’s not a surf session – that’s a mess. Skip it.

Sunday the 30th sees the swell drop to 7ft in the morning, then 8ft in the afternoon, still from the WSW. Morning has rain showers and a cross-off wind from the SSW at 19 mph, which keeps the surface clean, but the combined energy is only 577 to 804, and the waves are just ordinary. The afternoon clears up but the wind swings SW at 22 mph – still cross-off, but not enough quality to bother.

Monday the 31st is another write-off. Swell around 10ft dropping to 7ft through the day, but the wind is cross-onshore from the NW then WNW, 19 to 12 mph, making it lumpy and choppy. Tuesday the 1st of September, the swell drops right off to 4ft, and the winds are light but still cross or cross-off. Poor conditions all around.

We finally get a little glimmer on Friday the 4th of September. The morning shows a 5ft swell from the west, period 9 seconds, with a light SW breeze at 9 mph that’s cross-off. The combined energy is only 384, so it’s weak, but the surface is clean. It’s marginal, but if you’re itching, that’s your best early call. Still, nothing special.

Then on Saturday the 5th of September, we’ve got the closest thing to a standout in this whole run. Saturday morning brings 6ft from the west, period 10 seconds, with a light WSW breeze at 6 mph – cross-shore, but light. The combined energy is 670, moderate. That’s okay. But the real moment is Saturday afternoon: 6ft from the west, still 10-second period, and the wind goes light ESE at 6 mph, *cross-off*. The report says it expects good surf conditions, and for this stretch, that’s as good as it gets. Clean waves, manageable size – this is the session to aim for. Not big, not epic, but surfable and clean.

After that, Sunday the 6th has 5ft to 6ft from the west, but the wind picks up again – SSW then SW at 12 to 19 mph cross-off, but the quality is only marginal. Monday the 7th through Wednesday the 9th of September sees the swell dropping steadily from 6ft down to 3ft, with winds mostly onshore from the north or cross-off from the east. The combined energy is low, under 543, and the conditions are poor overall.

There is a tiny window on Wednesday the 9th of September morning: 3ft from the west, period 7 seconds, with a light ESE breeze at 6 mph cross-off. Energy is only 58, and the waves are very ordinary, but at least the water is clean. That’s about all I can say for it.

From the 10th of September onward, the swell fizzles to almost nothing – 0.5ft to 4ft, with the combined energy under 500, and winds are mostly onshore or strong cross-shore. The long-period swell on the 13th (15 seconds) is from the west, but it’s only 3ft with an onshore wind. Not happening.

So, to wrap it up: the one session that stands out as the best of a rough bunch is Saturday the 5th of September afternoon at St Agnes. Clean, cross-off wind, 6ft west swell, 10-second period. It’s not gonna be pumping, but it’ll be the cleanest you’ll see in this forecast. If you can only paddle out once, make it then. The rest? Honestly, I’d take a long look at the wind forecast before you bother waxing up.
