The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks. Straight up, it's been a rough stretch, and the truth is, we’ve got a long gap before anything really worth getting wet for shows up. We're looking at a dry spell from now until around the 15th of September, with nothing but poor conditions and cross-onshore junk. The water's hanging around a touch warmer than normal for this time of year, so at least you won't freeze while you're sitting there watching the mess.
The first glimmer of hope isn't until Tuesday the 17th of September. Thursday the 17th, to be exact. We’ve got a morning session that almost feels like a reward for hanging in there. Swell is a tiny 3 ft from the W, with a period of 9 seconds—nothing to write home about, but the wind is glass. Absolutely glass. Calm wind, zero onshore push. For Gwithian, that is a rare treat, so if you're a beginner or just want to practice without battling the chop, this is your window. Combined swell energy is a weak 118, so it’s not powerful, but it’s clean.
Later that same day, the glassy spell fades as a light onshore wind picks up, and the swell drops to 2 ft, so the morning is your only play here.
After that, it's back to less-than-ideal conditions for the rest of the window. We get a bit of a pulse on Wednesday the 23rd of September with a 4 ft to 4 ft WNW swell and a very long period of 15 seconds, pumping the combined energy up to 717. That's a proper groundswell. But the wind is a moderate cross-shore from the NNE at 16 mph, churning it up. That long period stuff at a beach break like Gwithian tends to get a bit straight and sectiony, so don't expect perfection. It's going to be lumpy, more of a challenge for the experienced crew than a clean, rippable day.
Look, this is one of those forecasts where patience is the game. The standout is undeniably that Thursday morning on the 17th of September—it's the only time in the whole outlook where the stars align for a clean, if small, surf. Everything else is either blown out or too weak to bother with. Keep an eye on it, but don't hold your breath.

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.
