The Lowdown
Alright, Rusty here. Let's take a look at what's on the menu for Gwithian over the next couple of weeks.
Right off the bat, I gotta be straight with you – it's a grim picture for a while. The first few days are a total write-off. Monday the 10th through Tuesday the 11th, we're looking at tiny, weak waves with poor surf conditions. The water's a touch warmer than usual for this time of year, sitting at 65°F, but that's about the only good news. You’d be better off finding a rock pool.
We then move into a long, frustrating stretch. From Wednesday the 12th of August all the way through to the 22nd, the surf is either too small, too messy, or the wind is just plain wrong. There are a couple of mornings where it cleans up, like the 12th with a clean 3ft swell from the W, and the 19th with some clean 3ft waves from the W, but they're just "surfable" at best. Nothing to get excited about. The combined energy might bump up a bit – you see a moderate 126 on the 12th and a 142 that afternoon – but the conditions just don't let it happen. It's frustrating because the consistency is there, but quality is lacking.
The real story, and the only time I'd even think about paddling out, is the very end of the run. On the 25th of August, Tuesday, we see a bump in size. The morning shows a 4ft swell from the W, with a combined energy of 441, which is serious. But here's the kicker: the wind is cross-onshore from the WSW at 12 mph. That's going to chop it up. By the afternoon, the swell pushes up to 5ft from the WSW, with 428 energy, but again, cross-onshore wind and choppy. At this size, it's pushing into expert territory for the crew looking for a challenge. For everyone else, it's probably more interesting for the kite surfers than for a clean paddle session.
So, to be brutally honest, I can't give you a standout session in this whole 16-day period. The best of a bad bunch is the 25th, but the wind is going to ruin it. The gaps of flat, poor surf are relentless.
Rusty, signing off.

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.
