The Lowdown
Right then, let’s have a look at what’s coming up for us here. I’ll be honest, the next week and a bit is looking pretty grim. We’ve got a long dry spell with hardly anything worth paddling out for. From now, right the way through until the 7th of September, it’s a write-off. The forecast is showing tiny, weak swell or messy, blown-out conditions. Just not worth the wetsuit.
The only real glimmer on the horizon, and I mean a proper glimmer, is for the 8th of September. Gwithian, which is fairly exposed to the west-northwest, is looking at a massive pulse of energy. We’re talking a solid 13ft of swell from the west-northwest, with a very long period of 16 seconds. The combined energy reading is a whopping (8522), which is serious, serious power. It’s a groundswell of real magnitude. The wind is forecast to be a fresh offshore from the south, which would groom it into perfection. Now, this is a big one – 13ft is pure expert territory, and a long-period west-northwest groundswell like this will be a proper beast. It’s a standout, but it’s one for the experienced crew only. If you’re not confident, give this one a miss. The water temp is around 63°, which feels about average for the time of year.
Before that, the only other thing worth a mention is on the afternoon of the 25th of August. We get a tiny 2ft from the west-northwest with a gentle offshore breeze. The energy is only (103), so it’s weak, but it might be the only surfable wave in a sea of flatness.
The big event is definitely Monday the 8th of September. That morning’s session at Gwithian is the one to circle. It's a clean, powerful, heavy hitter for the experts. The afternoon session on the 8th remains big at 11.5ft, but with a cross-shore wind, it won't be as clean. So, get it while it’s good.

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.
