The Lowdown
Alright, let's get this straight. The next week and a half is gonna be a tough one for us. We've got a lot of days with waves, but they're tiny, messy, and blown out. It's going to be a waiting game.
The first real chance of anything decent won't come until Monday, August 17th. Even then, it's marginal. Swell pushes up to 5ft from the WNW, but the wind is cross-shore and bumpy, so it's not going to be clean. The energy is moderate, around (346), but it's just not gonna be worth paddling out for anything but a grovel.
There's another pulse of energy mid-week, but it's all cross-shore and lumpy. The swell gets bigger, but the wind ruins it. That's a kite-surfing wind if anything.
Then, finally, things start to click. From Thursday, August 20th, the wind turns offshore and glassy. The swell is still solid, around 6ft from the W, with moderate-strong energy (426). This is when the window opens. Gwithian will be clean and the rides will be worth it.
The standout, though, has to be Friday, August 21st. The swell holds at 5ft from the W, with a moderate offshore ESE wind, and energy is solid (357). This is the one to circle. Clean, consistent, and with that offshore breeze, it's going to be proper. The crowds will be there, but for a wave this good, it's worth sharing.
The following day, Saturday, August 22nd, is still promising, but the wind is stronger and the swell backs off a touch. It’ll be a fun, punchy option, but the day before is the pick of the bunch.
So, keep your head up. The first week is a write-off, but there’s a gem waiting for us at the end of the tunnel.

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.
