St Agnes Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a proper look at what St. Agnes has lined up for us over the next couple of weeks.

We've got a bit of a mixed bag, with some solid potential but a fair bit of wind to work through. The water is sitting at 64°, which is a touch warmer than normal for this time of year, so you can leave the thick wetsuit at home for a while longer.

The week starts off a bit of a write-off. Wednesday and Thursday are looking at a messy, lumpy 5ft to 6ft of swell, with a short period of 6-8 seconds, pushed around by a fresh 19 mph cross or cross-off wind. The wave energy is in the moderate range (241-406), but it’s just not going to be pretty. Not worth paddling out for.

That changes on Saturday the 5th. This is the standout of the first week. The morning is crystal clear with a glassy, zero wind condition. We’ve got a 4ft groundswell rolling in from the west-northwest with a long 11-second period. The energy is moderate (440), but those clean, glassy conditions will make it feel like a completely different break. The afternoon will be glassy again, with a 4ft swell from the west. The water will be clean as a whistle. This is the pick of the week for sure, but keep in mind it can get crowded here, and with conditions this good, you’ll have company.

Sunday the 6th drops right off. A tiny 2ft leftover swell with a short period, so you’ll be scratching for anything. The wind is offshore in the morning, so it’ll be clean, but there's just not enough water moving. The energy is very weak (73). This is a day to stay on the beach.

The following week is a tale of two halves. Monday through Wednesday the 9th is a no-go – strong onshore winds, mostly from the west and north-west, gusting to 22-25 mph, create a choppy, messy sea surface. The swell is actually there, 5ft to 8ft, and the energy is strong (363-1138), but the wind just ruins it. The setup is more interesting for kite surfing than paddle surfing during this stretch.

Then Thursday the 10th and Friday the 11th bring a lot of water, but it's messy. A solid 7ft to 10ft of swell with a short period, but it's hitting us with a direct onshore wind. The energy is high (578-1406), but it's for experts only, if anyone.

Now, the real standout of the entire forecast is Saturday the 12th of September. The morning offers a solid 7ft groundswell from the west, with a long 12-second period. The energy is very strong (1369). The wind is a gentle 9 mph offshore from the SSE. That’s a dream combination for a point break like this. The conditions will be clean and lined up. The afternoon stays clean with a 7ft swell and a cross-off wind. This is the one to circle on the calendar. It’s a week and a half out, so it’s not a lock, but it’s got all the ingredients for a classic session.

We get a bit more wind on Sunday the 13th, but Monday the 14th looks promising again. A 6ft west swell with a 10-11 second period, and a clean offshore wind from the SSE. The energy is strong (918). This is another solid option for a good paddle.

The final few days of the forecast, from the 15th onwards, look like they’ll get blown out again by strong cross-onshore winds from the west and north-west, with a couple of 7ft to 10ft swells that will be too messy for a good time. The energy will be there, but the quality won't.

So, to wrap it up: Saturday the 5th for a clean, glassy session, and Saturday the 12th of September for the big, clean groundswell. Those are your two best bets.

Rusty.
