Gwithian Surf Forecast and Surf Report

Hey crew, Rusty here. Let’s slice through the next couple of weeks in Cornwall.

Honestly, the first week and a half is a total bust. Don’t even wax up. There’s a huge gap from now until the back half of September with nothing but poor surf. The wind’s all cross-shore or cross-on, making everything lumpy and choppy. The water’s a touch warmer than normal for this time of year at 64°.

Swell shows up between 2ft and 7ft, but it’s paired with funky wind and short periods. The wave energy is moderate at best (like 570 early on), but it’s all blown out. A few days have a decent groundswell (10-12 second period), but the onshore wind ruins it. Just nasty.

Then, a huge light at the end of the tunnel. Circle Tuesday, September 23rd.

Gwithian (Cornwall) is the only spot that matters. Tuesday morning cleans up with a 8ft swell and a light offshore ESE breeze at just 6 mph. The combined wave energy is a solid 727. It’s clean but with short period (8 seconds), it’ll be a bit dumpy – better for competent surfers. But the afternoon is the real standout. You’re looking at a massive 10ft groundswell from the west with light east winds blowing offshore. The combined energy hits 1569 – that’s a heaving, powerful ocean. With a 10-second period, this is real deal, heavy beach break waves. It’s for experts only. This is the session to wait for. It’s a long way out, so keep tabs on it, but the signs are good.

Wednesday, September 24th, still has solid juice with a 8ft morning swell from the WNW and moderate offshore ESE wind. The energy is still high at 1512 and a 12-second period gives it real shape. The wind is a bit stronger at 15 mph, so it won’t be as glassy as Tuesday, but still excellent for the experienced crew.

After that, it drops off quick.

Bottom line: Forget this week. The gold is on that Tuesday. If you can wait, Tuesday afternoon is the one. Big, clean, powerful surf for the first time in ages.

Rusty, signing off.
