The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Gwithian over the next couple of weeks.
Right off the bat, I’ve got to be straight with you—this is a long, dry spell we’re staring down. The first real glimmer of something worth paddling out for doesn’t show up until Tuesday the 15th of September. Before that, it’s a whole lot of wind and chop. From the 7th right through to the 14th, we’re looking at a solid run of poor conditions. The wind is predominantly onshore or cross-onshore, and the surf is messy. The swell energy is moderate at best, but it’s all blown out. You’d be wasting your time.
Now, Tuesday the 15th of September morning is the one to circle on the calendar. Finally, we get a break in the weather. The wind goes glassy out of the south at 0 mph, and we’ve got a solid 6 ft swell rolling in from the WNW with a long 12-second period. That’s a proper groundswell, packing a lot of energy (1016) and it’s going to be clean as a whistle. For a spot like Gwithian, which is fairly exposed to that WNW direction, this is about as good as it gets. The water temperature is about average for the time of year, so nothing unusual there. This is the standout. It’s a beginner-friendly break, so the size is manageable, but with that long period, expect some nice, lined-up waves. Just be aware, crowds are often here, so if you can get out early, you’ll be laughing.
The afternoon of the 15th is still okay, but the wind picks up to a light cross-shore, and the swell drops a touch to 6 ft. It’s a marginal option, but nowhere near as good as the morning glass-off.
After that, things get a bit wild again. Wednesday the 16th sees strong winds, and by Thursday the 17th, we’ve got a massive 13 ft swell hitting, but with a fresh cross-onshore wind. That’s a big, messy, blown-out wall of water. The combined energy is a beastly 3950, but it’s for experts only in those conditions, and honestly, it looks more like a day for the kite surfers than paddle surfers. The wind stays strong and the swell stays big through the weekend, with the wind staying cross or cross-onshore, making it all pretty lumpy and uninviting.
So, bottom line: the first week is a write-off. The second week gives us one real gem of a session on Tuesday morning, the 15th. After that, it’s big and wild. Keep your eyes on that Tuesday morning window.
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.
