St Agnes Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s look at what’s on the table for St Agnes for the next couple of weeks. Straight up, I gotta be honest with you – this is one of those outlooks where you might want to keep the board in the van for a while. The entire run is plagued by either strong, wonky winds or just cross-onshore junk that’s gonna turn the surface into a washing machine. There’s no standout session here, not really. We start off on Friday 28 August with rain and a moderate cross-shore chop on a tiny 4ft swell from the WSW, period a weak 6 seconds – it’s a no-go. The water’s sitting at 65°, which is a touch warmer than normal for this time of year, but that’s the only nice thing about it. The problem is the wind stays messy or too strong for days on end.

Moving into Saturday 29 August, the swell jumps up to 8ft in the morning from the SSW, with a cross-offshore wind that’s cranking 25 mph. The wave energy is moderate (720), but let me tell you, that wind speed is going to make paddling a fight, and the period is only 8 seconds – short-period wind swell. That afternoon it goes berserk with a 12ft swell from the WSW and a 28 mph cross-onshore. That’s expert-only territory and it’ll be a mess. Sunday 30 August looks a bit cleaner in the morning, with a 6ft swell from the WSW (period 9 seconds) and a moderate cross-offshore at 16 mph. The energy is moderate (475), but the combo of a solid swell with that offshore wind might just give you a few lined-up walls if you’re willing to take the risk. But honestly, the guidance still calls it poor, so don’t expect magic.

The first week of September looks bleak. Monday the 31st pumps up to 8ft from the west, but it’s cross-onshore with a fresh breeze. That’s just messy. Tuesday the 1st drops back to 4ft, but it’s still cross-onshore and choppy. There’s a gap here of several days with no real reason to paddle out. Wednesday 2 September morning has a tiny 3ft swell with clean cross-offshore wind, but it’s barely a ripple – wave energy is weak (121). Not worth the drive.

Things get a little more interesting from Thursday 3 September onward, with waist-to-chest-high swell around 7ft from the WSW, periods around 8-9 seconds. The wind goes cross-offshore on the Thursday afternoon and Friday afternoon, which is a step up. The wave energy sits in the moderate range (463-503), but the problem is every morning and afternoon still has a cross or onshore component that’ll keep it bumpy. No true glass-off here. Then Saturday 5 September brings a light onshore breeze and a dropping 4ft swell – not worth it.

We hit another lull through the second week, with swell dropping to 2ft or less, and on Sunday 6 September it’s barely breaking (energy just 85-90). There’s a brief pulse of 7ft on Monday 7 September from the west, but it’s cross-onshore again. Tuesday 8 September sees a fresh cross-shore that’s lumpy, and then it’s all downhill from there into tiny, wind-affected slop right through to Saturday 12 September. The periods get short (5-7 seconds) and the energy is weak.

So what’s the pick? Honestly, this is a tough one. If you really need to scratch the itch, your best bet is the Saturday 30 August morning session – that 6ft WSW swell with a moderate cross-offshore (clean) is the most balanced moment in the whole period. Or the Thursday 3 September or Friday 4 September afternoons, when that 7ft swell meets a cross-offshore breeze, giving you the best chance at a clean, lined-up wall. The period is 8-9 seconds, so it won’t be groundswell perfection, but it’ll be the least ugly of the bunch. Wear a hood if you can – it’ll be woolly out there.

Keep your expectations low. This is a quiet run for St Agnes, but forecasts can change, so don’t write it off completely. Stay salty.

Rusty.
