The Lowdown
Alright folks, Rusty here. Let's have a look at the outlook for Gwithian. It's a bit of a tough pill to swallow, I'm not gonna lie. We've got a long stretch ahead with some serious swell on the way, but the wind is going to be a real pain in the backside for most of it.
The water at Gwithian is sitting at 64°, which is a touch warmer than normal for this time of year, but that's where the good news starts and ends for a while.
We kick off on Monday the 7th of September, and straight away it's a write-off. There's a solid 8ft of Westerly swell, with a combined energy of 1783 (strong), but it's blowing onshore from the WNW at 12 mph. The whole day is a mess of onshore junk. Tuesday the 8th is no better, with a fresh 19 mph cross-on wind destroying a 6ft swell. This is pure frustration.
Wednesday the 9th sees the swell drop to 4ft, but it's still cross-on. The surf quality is poor. Thursday the 10th is the smallest day of the whole run, with only 2ft of weak swell (66 energy) and a clean cross-offshore wind in the morning. It's clean, but there's nothing to ride.
Friday the 11th is the first spark of hope. We get a 5ft swell from the West, with a light 6 mph cross wind. The wave comment calls it marginal, but it's the closest we get to something clean with a bit of size. By Saturday the 12th, the swell fades back to 3ft.
Sunday the 13th brings a return of 5ft of West swell, but it's back to onshore. The following week is a repetitive cycle of onshore wind and fading swell, with size dropping from 6ft on Tuesday the 15th all the way down to 2ft by Monday the 22nd of September. The wind is never favourable.
So, the honest truth? There is no standout session in this 16-day window. The closest thing to a surfable day is Friday the 11th of September, with that 5ft West swell and light winds. But even that’s a long shot. The rest of the time, the wind is just too strong and from the wrong direction. If you're a kite surfer, there's plenty of wind, but for a paddle surfer, it's a tough run. The forecast can change, but right now, it looks like a blank run.
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.
