The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Gwithian over the next couple of weeks. I’ll be straight with you – it’s a rough stretch ahead.
Looking at the whole 16-day window, the honest truth is there’s nothing worth getting excited about. We’ve got a long, long gap of flat, messy, or just plain horrible conditions. The first real glimmer of anything surfable doesn’t show up until Wednesday, August 12th, and even then, it’s pretty ordinary. Before that, we’re talking about a solid 10 days of virtually no surf. The water temperature is sitting at about 65°, which is a touch warmer than normal for this time of year, but that’s about the only nice thing I can say.
Let’s break it down.
Wednesday, August 12th – The Only Slight Glimmer
After a brutal run of tiny, choppy, and onshore junk, we finally get a small window on the morning of the 12th. The swell is a weak 3 ft from the west, coming in at a 10-second period. The combined energy is weak at 149. The wind is light out of the ESE, blowing straight offshore, which will keep the surface clean. It’s surfable, but it’s very ordinary. The waves will be small, soft, and unexciting. It’s a beginner-friendly wave, but don’t expect any power. For a seasoned surfer, it’s barely worth a paddle.
The Rest of the Window
The rest of the forecast is a write-off. The swell stays small, the wind is all over the place – mostly cross, cross-on, or straight onshore – and the periods are short. There’s a bit of a bump in size on August 5th, with waves hitting 6 ft, but the wind is a howling 19 mph onshore (WNW), making it a complete mess. That kind of energy (331) is just a washing machine. For the experienced guys, it’s a no-go. For anyone else, it’s dangerous.
August 16th shows a little more size, with 5 ft to 6 ft swell, but the wind is onshore or cross, and the period is a short 6 seconds. Expect bumpy, disorganized lines.
The Verdict
Honestly, for Gwithian, this is a blank run. The consistent nature of the break means it usually doesn’t stay this flat for long, but this time it has. I’d leave the board in the car for a while. If you’re desperate for a paddle, the morning of the 12th is your only real shot, but keep expectations on the floor. This setup looks more interesting for a kite surfer than a paddle surfer for most of the period.
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.
