The Lowdown
Right then, let's have a look at what's on offer for Gwithian over the next couple of weeks.
Honestly, it's a pretty grim outlook for the paddle. The whole 16-day period is a write-off for good surf. There's nothing here that's worth getting excited about. The first few days are tiny and messy, and even when the swell picks up a little, the wind is always in the wrong direction. We're looking at a solid two weeks of poor surf conditions, with no real standout windows. It's a long, flat run.
The first proper bump in size doesn't show up until Saturday the 25th of July, with a 5ft to 6ft WNW swell pushing in. But the wind is cross-onshore from the NNW, making it a choppy, lumpy mess. The combined energy jumps to 209 then 280, which is at least moderate, but it's all for nothing with that wind. Sunday the 26th is much the same, with a 5ft to 5ft swell and the same onshore breeze. That's no good for anyone on a surfboard. For a beginner spot like Gwithian, anything over 5ft is already a bit much, and with that wind, it's a total no-go. The water temperature is about average for the time of year, so nothing to write home about there.
The rest of the period is a mix of tiny swells, poor winds, and lots of cross-shore chop. Even the few days with a longer period, like the 10-second swell on the 29th of July, are ruined by onshore or cross-onshore winds. The best you can say is that the wind is light on the 27th and 28th of July, but the swell is only 4ft and 3ft, and the period is short. It's not worth the drive.
Given the persistent onshore and cross-onshore winds combined with the beach break setup, this looks far more interesting for kite surfing than any kind of paddle surfing. It's a blank run, and for this area, it's a pretty normal stretch of poor conditions.

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.
