The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for Gwithian over the next couple of weeks.

Right off the bat, I gotta be straight with ya – it’s a tough start. We’ve got a long dry spell where the surf is just not happening. From now until the 20th of August, it’s pretty much a write-off for anything decent. The swell is tiny, the wind is all over the shop, and most of the time it’s choppy or onshore. You’ll see a few small clean windows on Wednesday morning the 12th and Tuesday the 18th, but with swell around 2 ft to 3 ft, it’s barely a ripple. The sea looks more like a washing machine than a surf break. Honestly, for paddle surfing, you’re better off finding something else to do.

Then, just when you think it’s a lost cause, things flip. Friday the 21st of August is your absolute standout. This is the one to circle on the calendar. We’ve got a proper pulse of 6 ft to 8 ft swell rolling in from the WNW, with a period of 7-8 seconds. The energy jumps right up – we’re talking a combined energy of 432 to 692 here, which is a serious shove of water. The real beauty of it is the wind: a light to gentle offshore breeze from the ESE. That’s going to keep the surface clean as a whistle. This is good, solid, surfable size, but at 8 ft it’s getting up there – probably a bit much for beginners, but for the rest of you, it’s game on. Just a heads-up, Gwithian can get crowded, and with a forecast like this, you can bet your mates will be out.

Saturday the 22nd, the wind switches back onshore from the W and that’s it – the quality tanks straight away.

So there you have it. A long, lean stretch of nothing followed by one proper golden morning. Get on it on the 21st, because the window is tight.

Rusty.

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.
