St Agnes Surf Forecast and Surf Report

Alright folks, Rusty here, checking in on the St Agnes stretch for the next couple of weeks. Let’s be straight up, the next ten days or so are a bit of a write-off, so I’d say hang loose and don’t bother waxing up just yet. We’re looking at a long, frustrating gap before things finally turn on.

The water is sitting at 65°, which is a touch warmer than normal for this time of year, so at least the wait won’t be freezing.

We kick off Saturday the 29th with a fresh swell from the SW pushing 8 ft, but a strong 19 mph cross-off wind is making a mess of it. The energy is moderate at 606, but it’s just poor surf conditions. It stays ugly right through the weekend and into the start of next week. Monday the 31st sees a 10 ft W swell, but with an 19 mph cross-on wind, it’s lumpy and blown-out – definitely for experts only if you’re brave, but honestly, it looks more interesting for kite surfing than paddle surfing.

This grim pattern holds. We get pulses of swell, like Wednesday the 2nd with a 7 ft WSW swell, but the wind stays fresh and cross-off, keeping the quality poor. The energy peaks hard on Monday the 4th with a 7 ft W groundswell at a very long 12 seconds, giving us 1170 in energy, but the cross-shore wind ruins it; it’s lumpy and choppy. The same story plays out for most of the first week of September – moderate energy, but the wind just won’t cooperate.

After a solid ten days of garbage, the light finally appears. The standout window is Monday the 7th of September. We get a 6 ft W swell with a long 11-second period, delivering 981 in energy. But the real story is the light 6 mph SE cross-off breeze and clean conditions. For the first time in this forecast, we’ve got clean waves. This is the first genuine, high-quality option on offer.

However, the real gem is shaping up for Friday the 11th of September. This is the one to circle. We’re looking at a powerful 10 ft W swell with a very long 14-second period, cranking out a massive 5574 in energy – that’s strong, serious groundswell. The wind is light and offshore from the S at 9 mph, making for gentle, clean conditions. This is prime for experienced surfers. The only caveat is that long-period, powerful swell can break a bit straight at beach breaks, so keep that in mind, but with offshore wind, St Agnes should hold up well. Saturday the 12th keeps the good vibes going with a clean 5 ft W swell.

So the story is simple: wait out the junk until the 7th for a taste of clean surf, but hold your breath for the 11th – that’s the one worth taking a day off for.

Rusty.
