Gwithian Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it, and I’m not gonna lie, it’s been a tough stretch for Gwithian. There’s a lot of onshore wind and messy conditions in the first week, so we’ve got a bit of a wait on our hands.

The first decent window we see is Saturday the 5th. The morning is looking like the standout for the whole 16-day run. We’ve got a clean 5 ft swell pushing in from the WNW, and the wind is *glass* – dead calm. That’s a proper treat. The swell period is a healthy 12 seconds, so we’re talking proper groundswell with good shape and energy. The combined energy is moderate (654). Water temp is sitting at 63°, which is about average for the time of year, so no nasty surprises. It’s a beginner-friendly break, so if you’re newer to it, this is your moment. The swell direction is a near-perfect match for the break. Just keep in mind that crowds are *often* here, so you won’t be alone, but it’s worth it for those clean lines.

Now, the afternoon of Saturday the 5th is a bit of a letdown. The swell drops to 4 ft and the wind swings cross-shore, making it look a bit ordinary. We then hit a dry spell. Sunday the 6th is tiny with weak energy (95), and Monday the 7th brings a big jump in size – 8 ft on Monday morning! But it’s wrecked by a strong onshore wind, so it’s just a messy, lumpy beast. That raw energy is high (1822), but it’s not for paddling. The whole of the first week, right through to the 10th, is mostly blown out or too small to care about.

There’s a glimmer on Saturday the 12th morning. The swell is a clean 3 ft from the WNW with a 10-second period, and the wind is light and cross-shore. It’s marginal but surfable. The energy is moderate (413).

The next real highlight comes on Tuesday the 15th of September. Another morning with glassy conditions! This time we’ve got 4 ft of swell from the west, period at 9 seconds. The combined energy is moderate (290). It’s not the biggest day, but clean, small waves on a consistent break are a joy. The wind is a slight air from the east, keeping it smooth. The afternoon picks up a bit of cross-onshore wind, so the morning is the call.

Wednesday the 16th is a nice little tail-off. Morning sees 3 ft with clean cross-offshore wind, and the afternoon goes completely glassy with 3 ft from the WNW. It’s ordinary, but it’s clean and there are waves to be had.

After that, the 17th and 18th are a write-off. Strong onshore winds and tiny, weak swell. The energy drops right off (85 to 176), and it’s back to the waiting game.

So, to sum it up: the clear winner is Saturday the 5th of September, morning session. That glassy, long-period groundswell is the best on offer. For a close second, get up early on Tuesday the 15th for another glassy morning. The rest of the time, you’re fighting the wind or the small stuff.

Rusty.
