The Lowdown
Alright folks, Rusty here with a look at the surf ahead for our local stretch.
Right off the bat, I gotta be straight with you – this is a tough one. The next couple of weeks are looking pretty grim, with a whole lot of flat, blown-out, or just plain messy conditions. We’ve got a solid run of days where you’re better off doing something else. From the 4th through the 6th of August, it’s all poor surf, blown out by fresh cross-shore winds. There’s a tiny window of glassy conditions on the morning of Saturday the 8th, but with the swell only 1ft, it’s barely a ripple. From there, we drift through a long stretch of tiny, weak surf until about the 12th. The most hopeful sign comes further out, towards the end of the forecast.
The only thing that catches my eye is Gwithian on Wednesday the 19th of August. We’re looking at a proper late-winter pulse here. The morning brings a solid 7ft swell straight out of the WNW, with a period of 9 seconds. The combined energy is pumping hard at 629 (moderate energy). Now, with that size, this is definitely expert territory – far too big for beginners. The onshore wind is a gentle breeze, which is a big positive, keeping things clean. It will be a raw, powerful session for those who know what they’re doing. Crowds are likely here as well, so get there early if you’re keen.
Honestly, through most of this 16-day run, the conditions are so poor that the beach setup here might be more interesting for the kite surfing crew than for paddle surfing, especially when the wind really starts howling mid-week.
Outside of that one morning on the 19th, there’s very little to get excited about. The waves are small and the winds are wrong. It’s one of those blank runs for the area. But chin up – it never stays poor forever.
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.
