The Lowdown

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

First off, I’ve gotta be straight with you – the start of the outlook is a real struggle. From Friday the 7th of August right through to Monday the 17th of August, there’s hardly a wave worth paddling for. The swell is tiny, mostly around 1 ft to 2 ft, and when it does bump up a little, the wind is all over the place. The water temp is sitting at 65°, which is a touch warmer than normal for this time of year, but that’s about the only good news. It’s a long, flat gap, and frustration is going to build.

Things finally start to show some life on Tuesday the 18th of August. The swell picks up to 6 ft from the west, but the wind is a light cross-onshore, and the conditions are just marginal. The combined energy is moderate at 495, but it’s not clean enough to get excited about. The break is pretty exposed, so it’s catching whatever’s out there, but the quality is missing.

The best of the bunch, if you can call it that, looks to be Wednesday the 19th of August in the morning. Swell is 6 ft from the west, period is 8 seconds, and the wind is light and cross-shore from the NNE. That’s a light cross-shore with small ripples, which is about as good as it gets in this window. Combined energy is strong at 443. It’s still a bit of a gamble, but if you’re desperate, that’s your window. For beginners, that 6 ft is starting to get a bit much, so be careful.

By Thursday the 20th of August, the swell jumps to 8 ft from the west, but it’s onshore and messy. Combined energy is very strong at 1234, but the wind is cross-onshore, and it’s a choppy mess. That’s more of a kite-surfing setup than a paddle-surfing one.

For the rest of the run into the 22nd, the swell stays solid but the wind is mostly onshore or cross-onshore, and the quality just isn’t there. The long period swells are few and far between, and the beach break setup here doesn’t help when the period is short.

Honestly, there’s no true standout here. If you’re desperate for a paddle, the Wednesday morning of the 19th is your best bet, but keep your expectations low. It’s a tough outlook, but that’s Gwithian for you sometimes.

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.
