The Lowdown

Gwithian’s been flat and gutless for days, and honestly, it’s a bit of a grind out there right now. The water’s sitting at 65°, which is a touch warmer than usual for this time of year, so at least you won’t need the thickest rubber.

The start of this stretch is pretty dead. From Thursday the 6th right through to the morning of Tuesday the 11th, we’re looking at dribbly little waves – nothing over 1ft, and most of it is junk. The swell’s weak as anything, with energy readings in the 20s and 30s, and the periods are short and uninteresting. You’d be fighting for ankle-biters. A few windows of glassy conditions pop up, like Saturday afternoon and Tuesday afternoon when the wind goes light and offshore, but there’s simply not enough water moving to make it worth the paddle. It’s a long flat spell, about five days of basically nothing.

Then things finally start to wake up. On Wednesday the 12th, the swell pushes up to 4ft with a period of 10 seconds, and the energy jumps into the moderate range (225). It’s still a bit onshore and lumpy, so not amazing, but at least there’s some push. Thursday the 13th is similar, maybe a touch bigger at 4ft, but the wind stays on it, making it soft and bumpy.

Friday the 14th morning is the first real glimmer. The swell has backed off to 2ft, but the wind is nearly dead and glassy. It’s clean, but the energy has dropped back to 119, so it’s small and a bit weak. Still, if you’re desperate, it’s the first time the surface isn’t a washing machine.

After that, it’s a bit of a mixed bag until the end of the window. The middle of next week, Tuesday the 17th and Wednesday the 18th, sees the swell kick up again – 4ft to 5ft – but the wind swings around and chops it up. By the 20th, there’s a bigger pulse of 5ft with a 10-second period and energy up at 424, but it’s buried under a moderate cross-onshore breeze. It’s going to be a messy, powerful close-out. Not really a surfer’s wave, more of a kite session if anything.

Honestly, there’s no standout day in this whole 16-day forecast. The waves never quite line up with the wind. If you’re going to get wet, Friday morning the 14th is your best bet just for the clean conditions, but don’t expect much. The rest is either flat or blown out. Keep the board in the car, but don’t get your hopes up too high.

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.
