Gwithian Surf Forecast and Surf Report

Alright, let’s get into it. The surf’s gonna be a mixed bag over the next couple of weeks, but there are a couple of windows where it’ll really turn on. For the most part, we’re looking at a lot of onshore wind and messy conditions, so you’ve gotta pick your moments.

We’re starting off with a bit of a flat start. The first few days are pretty grim. Thursday the 3rd and Friday the 4th are a write-off with onshore winds and poor surf. You’re looking at 5 ft to 7 ft of short-period, weak windswell, but it's all lumpy and choppy. No good.

Then, a real standout appears. Saturday the 5th of September is your best bet early on. Gwithian wakes up with a clean 5 ft groundswell from the west, with a nice 12-second period. The wind goes glassy – zero in the morning, just a slight air in the afternoon. The water temp is about average for the time of year at 63°. The wave energy is moderate to strong (646 in the morning, 421 in the afternoon). This is the one to aim for. It’s a beginner-friendly break, but with crowds being often, expect some company for those clean waves.

Sunday the 6th through to Wednesday the 9th is a bit of a mess again. A lot of cross-onshore and onshore winds, with swell picking up to 8 ft on Monday, but it’s all wind-affected. The 8 ft on Tuesday the 8th is too big for beginners, but the wind is cross-onshore and choppy, so it’s not even that good for experts.

We get a glimmer on Thursday the 10th of September. Clean cross-offshore wind with a 7 ft swell from the WSW. The period is only 7-8 seconds, so it’s a bit soft, but it’s clean and rideable. A good consolation.

Then a long gap of poor conditions from Friday the 11th right through to Monday the 14th. Onshore winds, cross-onshore winds, and generally small, weak swell. Not much to write home about.

Now, here’s the second standout, but it’s one for the experienced crew. Tuesday the 15th of September. A very long-period groundswell from the WNW, 16 seconds. This is big, powerful energy (1124 in the morning, 1519 in the afternoon). The swell height is 5 ft to 6 ft. The wind is cross-offshore, so it should be reasonably clean. But, with a period that long, it’s going to be walled-up and shifting a lot at the beach break. It’ll favour a point or reef setup more. It’s a bit raw, so not for the faint-hearted, but if you're an expert and you know Gwithian, you might find a gem. That’s the pick of the second week, but it’s a long-range call so keep an eye on it.

The final few days from Wednesday 16th onwards fade out into small, weak swell and poor conditions. The 18th of September barely has any energy at all (20 to 36 in the energy levels).

So, to sum it up: Saturday the 5th is your clear winner for clean, fun waves for everyone. Tuesday the 15th is a promising but raw option for experts. Don’t bother with the rest unless you’re desperate for a paddle.
