The Lowdown
Alright folks, Rusty here. We’ve got a long look ahead at Gwithian, and I gotta be straight with you – it’s a tough one. The next week and a half is a write-off. The wind is just miserable, swinging from strong cross-shore to straight onshore, and the swell is either too big and blown out or just plain messy. The water’s sitting at 64°F, which is about a degree and a half warmer than usual for this time of year, so the temp is nice, but you won’t be enjoying it. The combined wave energy is all over the place, hitting a massive 2421 (strong to very strong), but it’s all wind-chop and close-outs. Don’t even think about it unless you’re a kite surfer – that setup is more interesting for them than for paddle surfing.
We finally get a glimmer of hope on the 7th of September Monday morning. It’s still only a marginal call, with a 5ft swell from the west, period at 12 seconds (a proper groundswell), but the wind is a gentle cross-onshore from the SW. The combined energy is a moderate 698, but the conditions are still choppy. It’s not great, but it’s the first sign of life.
The real standout, and the only time I’d genuinely get excited, is the 12th of September Saturday morning. The wind finally plays ball – a light cross-offshore from the east. The swell is small at 2ft from the west, but with a long 11-second period, that’s a clean, lined-up little wave. The combined energy is a weak 181, but it’s clean. This is a classic “small but perfect” session. The crowds at Gwithian can be an issue, but on a small day like this, you’ll have plenty of room. This is the best on offer in the whole 16-day window, but it’s a long way off, so keep an eye on it.
After that, we drop right back into the doldrums with nothing but small, clean, but basically flat conditions for the rest of the forecast.
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.
