Gwithian Surf Forecast and Surf Report

Alright, let’s get into it. This stretch here for Gwithian is looking pretty average for the most part, with a couple of promising windows later on that have some real potential.

Right now, we’re kicking off on Tuesday the 25th with a small, clean 2 ft WNW groundswell coming through at 10 seconds. The wind is light and off from the ESE, so conditions are actually quite clean, even if the energy is minimal. The swell energy is weak at just 93 to 110, so there’s not much push. It’s a beginner-friendly day but nothing to get excited about. The water temp is about average for this time of year, so no surprises there.

Wednesday and Thursday are pretty lackluster, with tiny, weak swell dropping down to 1 ft to 2 ft and shorter periods of 8 seconds. Winds are cross-off or light, but there’s just no power in the water. Combined energy slips down as low as 36, so it’s really just a paddle-around kind of week.

Friday the 28th through the weekend gets a bit more size, but the wind shifts onshore and gets messy. By Saturday the 29th, we’re seeing a fresh cross-onshore breeze at 22 mph and 7 ft to 8 ft of wind-affected swell. The energy is moderate to strong at 444 to 1059, but the quality is poor. The period is only 7-9 seconds, and with strong onshore wind, Gwithian turns into a lumpy, choppy mess. If you’re kiting, maybe this is your moment, but for surfing, forget it. The same story continues through to the end of the first week of September, with strong winds and messy conditions, even as the swell fluctuates.

Now, here’s where it gets interesting. On Tuesday the 8th of September, the forecast shows a serious pulse of groundswell arriving. By the afternoon, we’ve got 7 ft of WSW swell with a long period of 14 seconds, combining for very strong energy at 2101. The wind is a light, cross-off breeze from the ENE at just 6 mph, which will keep things clean. For experienced surfers, this is the standout session of the whole run. That long period swell will be lining up nicely at Gwithian, though it can sometimes break a bit straight at a beach break like this. Still, the conditions look excellent.

Then into Wednesday the 9th of September, things get even better for the early birds. Morning brings a glassy, 10 ft swell from the west at 9 seconds. The wind is near zero, swinging into the SSW at just 3 mph, making for glassy conditions. The energy is massive at 2458, but with a short period, it’ll be a heavy, powerful wave. This one is strictly for the experienced crew, as 10 ft is expert territory. If you’ve got the skills, this will be the other top play of the outlook, with clean, powerful surf under that glassy sky.

So, to wrap it up: there’s a long gap of poor conditions from now until the second week of September. The two true standouts are the afternoon of Tuesday the 8th (7 ft, clean, long-period groundswell) and the morning of Wednesday the 9th (10 ft, glassy, huge energy). Keep an eye on those.
