The Lowdown
Alright folks, Rusty here. I’ve been staring at the charts for Gwithian and, well, I gotta be honest with you – it’s a tough stretch. The whole 16-day window is looking pretty barren for us. There’s not a single wave recommendation coming through for this spot, which is a real kick in the teeth. The surf is just too poor to get excited about from now through the end of the month.
The water is feeling a touch warmer than normal for this time of year, sitting at 65°F, which is about the only upside.
We start off with a few days of small, weak swell. On Saturday the 15th and Sunday the 16th, we’re looking at a tiny 1ft to 3ft swell from the west, with a short period around 8 seconds. The wind is a fresh cross-shore or cross-onshore breeze at 19 mph, so it’s gonna be lumpy and messy. The wave energy is really low.
Moving into Monday the 17th and Tuesday the 18th, we get a bit more size, maybe 3ft to 4ft, but it’s coming straight onshore from the WNW with a moderate breeze around 16 mph. The energy picks up a bit into the low hundreds, but the quality is still poor. It’s just a messy, windy mess.
Wednesday the 19th sees a similar story: 3ft swell from the west, onshore wind, and moderate energy. We get a little bump in energy on Thursday the 20th, hitting the “moderate” range, with a 5ft swell from the west. But that’s still onshore with a 16 mph wind, so it’s not going to be clean. For a beginner-friendly beach like Gwithian, that size starts to get a bit much, and the onshore wind will just chop it up.
The second week doesn’t offer any hope. There’s a tiny bump of 4ft from the north on Sunday the 23rd, but a fresh 22 mph cross-shore wind will make it a lumpy, cross-chop disaster. The end of the run gets incredibly small. From the 25th onwards, we’re looking at 0.7ft to 2ft swells. The wind does go glassy or offshore on the 27th and 28th, which is a tease, but with only 2ft of swell, it’s just not going to break with any push. The energy is pitifully low.
It’s a blank run. Gwithian is a consistent spot, so it’s a bit unusual to see a stretch this poor, but it happens. The forecasts can change, but right now, there’s nothing to paddle out for. Keep your board waxed and hope the next window brings something better.
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.
