The Lowdown
Alright, let's get into it. Gwithian’s not really giving us a lot to work with for the next couple of weeks. It’s a bit of a tough stretch, to be honest.
We’re looking at a long, patchy run here. After a pretty bleak start, there *might* be a little window opening up around Monday the 7th of September, but that’s a long way off and comes with its own issues.
For the first ten days or so, forget about it. The wind is just all kinds of wrong – mostly cross or cross-onshore, and often strong. The swell’s got no power behind it, a lot of short-period wind slop around 8 to 10 seconds. The combined swell energy is mostly in the weak to moderate range, struggling to get much above a few hundred (like 101), and the water's about 64°F, which is pretty normal for now. You’ll be looking at a lot of lumpy, choppy, blown-out conditions. Unless you’re into getting frustrated, stay out.
Things get interesting, but complicated, on Monday the 7th of September. The morning sees a big pulse of swell, 12ft from the WNW. The wind is light and mostly cross-on from the NW, which could clean it up a little. The combined energy is massive, hitting 1704 – that’s serious power. However, this swell is predicted to be too big for Gwithian itself for most surfers. That’s expert-only territory, and even then, the size might just make it a washing machine. The afternoon drops to a still-chunky 7ft, but that’s still big.
Into the 8th and 9th, the swell drops back but we get some cleaner windows. Tuesday the 8th has a 5ft swell from the west, with a proper 12-second period groundswell – that’s tasty energy (combined energy at 609). The wind goes cross-offshore from the SSE too, which could make for some clean, lined-up waves. This window on Tuesday afternoon is your best bet, but the forecast’s a little less certain that far out. The morning of Wednesday the 9th also looks clean with cross-offshore winds from the south, but the swell is smaller at 4ft.
Bottom line: There’s a very small, two-day window around the 7th and 8th of September. The 7th is far too big for most, but the 8th could be a proper little session if the wind plays ball. For the here and now, it’s a write-off. Keep an eye on it, these things can change.

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.
