The Lowdown

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

Honestly, for the first week, it’s a bit of a tough pill to swallow. The surf is small and the wind is messy. From Thursday the 6th right through to the 12th of August, we’re looking at a lot of ankle-to-knee high dribble, mostly under 3ft, with a lot of onshore and cross-onshore winds. The combined energy is weak, mostly between 16 and 102, so not much punch. It’s pretty much a write-off for a proper paddle session. There’s a brief window Saturday morning the 8th with a light cross-offshore breeze from the ENE, making it clean, but the swell is only 0.7ft with a 9-second period – that’s barely a ripple. You’d be better off with a longboard and a lot of patience.

Now, things start to get interesting around Wednesday the 12th. The swell picks up a bit, hitting 4ft from the W with a 10-second period, and the combined energy jumps to 226. Still, the wind is cross-onshore, so it’s not clean. The real standout window is Thursday morning the 13th of August. We’ve got a 4ft swell from the west, a 10-second period, and the wind goes glassy – dead calm. That’s your best bet. The water temp is about average for the time of year, nothing weird. The waves will be clean, but with a combined energy of 235, it’s moderate, not pumping. If you can get out there that morning, you’ll be in the right place.

The rest of the 13th and into the 14th, the wind swings back onshore and the swell drops. There’s a bit of a messy spell with stronger winds. Saturday the 15th and Sunday the 16th see a slight bump in size, with 4ft to 4ft from the W and WSW, but the period drops to 8 seconds, and the wind is onshore or cross-off. Sunday morning the 16th has a clean look with a cross-offshore from the south, but the 8-second period means it’ll be a bit weaker and won’t hold its shape as well as the glassy Thursday.

After that, Monday the 17th gets a bit bigger and lumpy – 5ft from the north with a short 6-second period and fresh cross-onshore winds. That’s messy and not great for a paddle. The rest of the second week fades back into small, weak conditions with onshore winds. The only other flicker of hope is Wednesday afternoon the 19th, when the swell bumps up to 3ft from the WNW with a 10-second period, but the cross-onshore wind will chop it up a bit.

So, to sum it up: the best surf on offer is the glassy Thursday morning the 13th of August. Get on it early. The rest of the 16-day window is mostly a waiting game.

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.
