The Lowdown

Alright folks, Rusty here. Let’s have a look at what Gwithian’s got cookin’ for the next couple of weeks. I’ll be straight with you – it’s a bit of a rough start, but there’s a glimmer of hope if you're patient.

The forecast opens with a lot of wind and junk. Friday the 28th and Saturday the 29th are a write-off. We’ve got cross-onshore breezes, some fresh to strong gusts, and lumpy, choppy surf that just ain’t worth paddling into. The water temp is sittin’ around 64°, which is about a degree and a half warmer than average for this time of year, so the water’s got a bit of extra warmth in it.

Sunday the 30th through to Thursday the 3rd of September is much the same story: strong winds, cross-shore chop, and poor conditions. We’ll see waves from 2ft up to 12ft, but it’s all messy. The bigger stuff on Monday the 31st hits 10ft with a 10-second period, but with onshore wind, it's a washing machine. Not worth your time unless you’re after a beating.

Now, Friday the 4th of September is a slight tease. We’ve got a 7ft swell from the west with a 12-second period – that’s a proper groundswell – but it’s still cross-onshore. Good energy though, moderate. It'll be choppy.

Here’s the standout: Saturday the 5th of September morning is your window. We’ve got a 4ft swell from the west, 11-second period, with a cross-offshore breeze from the northeast. That means clean, lined-up waves at Gwithian. The combined energy is moderate. The wind will be light, keeping the surface glassy. It’s a consistent spot, and while crowds are a possibility, you’ll be after the clean conditions. The swell direction is west, which matches up nicely with the optimum WNW. This is the one to aim for. It won’t be huge, but it’ll be fun and rideable.

After that, from the 6th of September onward, we drop off hard. Swell sizes get small, under 3ft, and the wind switches back to onshore or cross-onshore. There's a real flat spell from the 10th through to the 12th of September, with tiny waves and strong winds again. The 11th sees a 0.7ft swell with a 21-second period – that’s all period and no height, just a wash.

Overall, the first week is a bust, but don’t hang up your board. That Saturday the 5th morning is your best bet in this 16-day stretch. The rest is a waiting game.

Information about the Gwithian Surf forecast

The above surf forecast table for Gwithian provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Gwithian can be found by selecting the local surf guide option on the grey menu. Our Gwithian surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Gwithian) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Gwithian may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Gwithian is 6 km (4 miles) from Camborne. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Camborne. Camborne has rooms for a wide range of budgets as well as car hire and transport links.
