The Lowdown
Alright folks, Rusty here. Let’s get straight into it. I’ve got to be honest with you, the next sixteen days are looking pretty bleak for Gwithian. Most of the time, the surf is junked up by howling onshore winds or just lacks the size and shape to be fun. The good news? There’s one standout window that’s worth locking in your calendar, but you’ll have to be patient.
Right now, we’re looking at a long stretch of poor conditions. From Monday the 27th of July all the way through to the morning of Tuesday the 11th of August, it’s a write-off. The wind is predominantly onshore or cross-onshore, ripping the surface to shreds, and the swell is either small, weak, or just messy. The water is a touch warmer than normal for this time of year at 65°F, but that won’t help you when the waves are blown out.
The only real glimmer of hope comes on Tuesday the 11th of August. The morning looks like a rare moment of calm. The wind will be glassy, with a slight air from the NE, and the waves will be rolling in at a modest 4ft from the WNW. The swell period is a short 6 seconds, so it’s a weak windswell, but with no wind on the surface, it’s the cleanest it’s going to be all forecast. The combined energy is low at 108, so it’s not going to be a big day, but for a beginner-friendly spot like Gwithian, it’s the only session that’s even remotely surfable. We’re talking “surfable waves but very ordinary conditions” – a glassy one-star day is the best we’ve got.
For the rest of the period, the wind is just too strong or in the wrong direction. The swell does try to build later in the first week of August, with a pulse of 6ft and 7ft coming through, but it’s accompanied by strong onshore winds that’ll have it looking like a washing machine. By the time the wind eases, the swell is gone. This is a tough run for Gwithian, but it’s not going to stay poor forever. Keep your eyes peeled for a change in the charts.
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.
