Gwithian Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what the next couple of weeks have in store for us.

The overall pattern is a bit of a mixed bag. We’ve got a lot of swell on the way, but the wind is going to be the main story for a while, making things messy more often than not. It’s a long outlook, so patience is going to be key.

We start off on Sunday the 13th with a solid 5ft to 5ft WNW swell rolling in, but it’s coming with a cross-onshore breeze, so Gwithian is going to be choppy and poor. The water temp is sitting at 64°, which feels a touch warmer than normal for this time of year. This messy pattern with cross-onshore winds and middling swell hangs around through Monday and Tuesday. On Tuesday the 15th, we see the swell bump up to 6ft in the morning and 7ft in the afternoon from the WNW, with onshore winds. It’s got some energy to it (439 and 570), but the short 8-second period and onshore wind mean it’s going to be a bit of a washing machine.

Wednesday the 16th brings some cleaner conditions with clear skies, but the wind is still cross-onshore. The swell is a solid 7ft from the west with a 10-second period, and the energy is climbing (934). Still, it’s lumpy and not really inviting. Thursday the 17th is more of the same with onshore winds and 8ft swell. It’s big enough to be expert-only territory, but the wind is just not cooperating.

Now, here’s the standout. Friday the 18th. The morning shows a serious push of groundswell: 7ft from the WNW with a long 13-second period. The combined energy is massive at 1598, so there’s a lot of power in the water. This is proper groundswell, and at a beach break like Gwithian, that long period might make it a bit straight and fat, but there will be some clean-up sets. The catch? The wind is cross-onshore, so it’ll be choppy. Still, the energy is undeniable. If you’re an experienced surfer, the morning is the time to be out there. By the afternoon, the wind cranks up to 25 mph, and it gets messy.

The following week sees the swell drop off. Saturday the 19th has clean-ish skies and onshore wind, but the swell is back to 6ft. It’s surfable but nothing special. Sunday the 20th sees a shift to a cross-shore wind and 6ft swell. The energy is moderate (592), but the conditions are just average. There’s a gap in real quality from here until the very end of the period.

We get a bit of a curveball on Tuesday the 22nd. The morning shows 8ft swell from the NW with a short 8-second period, and a gentle cross-shore breeze. It’s marginal, but that size is only for experts, and the short period will make it crumbly. By the 23rd and 24th, the swell drops right off to under 3ft. The winds finally turn offshore and clean, especially on the 24th with a gentle offshore breeze and clean conditions, but the swell is tiny (2ft to 2ft) with very low energy (81). You’ll be on a longboard, if anything.

The very last day of the outlook, Sunday the 27th, offers a glassy morning with a 2ft west swell, but it’s essentially flat. The afternoon sees a strong cross-onshore blow up again.

To be honest, there isn’t a true blue-ribbon standout in this window. The best bet for a surfer looking for power is Friday the 18th morning at Gwithian, for the sheer size and energy (1598), despite the cross-onshore wind. The cleanest conditions with the best wind will be on Thursday the 24th, but you’ll be scratching for a wave on a 2ft swell. It’s a waiting game, lads.

Rusty.
