The Lowdown
Alright, I’m looking at the next 16 days here, and I’ve gotta be straight with you – it’s been a rough stretch for Gwithian. We’ve got a run of poor surf and messy winds that starts right now and doesn’t let up for a good long while. The energy’s there in the water, but the wind just won’t play ball.
The first real chance to even get a paddle in comes on Wednesday, 2nd September. That morning we’ve got some small swell – 3 ft from the SSW, period only 5 seconds, so weak, short-period stuff. Combined energy is just 97, so barely a ripple. But the wind is glassy – dead calm – and that’s rare. It’s surfable, but ordinary. For beginners, it’s about as safe as it gets, and the lack of wind means clean, crumbly little waves. It won’t blow your mind, but it’s the only window of glass in the whole forecast.
After that, it’s back to the struggle. The wind swings onshore or cross-shore for days, and the swell is messy. Gwithian is a fairly exposed beach, so it cops all that wind. With the strongest cross-onshore gusts and that 12 ft swell on the 29th of August (combined energy 2009), it’s more of a kite-surfing setup than a paddle-surfing one. The waves will be blown out, lumpy, and dangerous for anyone but experts.
The closest thing to a standout? Honestly, I’d mark the morning of Monday, 7th September. We get a 8 ft WNW swell, period 8 seconds, combined energy 642. The wind is light, cross-onshore from the NW at 3 mph, so it’s nearly clean. That’s the biggest, most promising swell in the whole run, but it’s still only marginal. If you’re experienced and hungry, that’s your best bet in the entire 16-day window. But don’t expect perfection.
The rest of the time, it’s poor. The wind is fresh to strong, and the swell is either too weak or too blown out. The water temperature is about average for this time of year, nothing unusual.
So yeah, hang tight, keep an eye on that early September window, but don’t hold your breath. The pattern’s been stubborn, and it might take a good shift in the weather to get Gwithian firing proper.

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.
