The Lowdown
Alright, let’s get real here. I’ve looked at the charts for Gwithian and, to be straight with you, it’s looking pretty grim. The whole sixteen-day window is basically a write-off for any decent surf. We’re talking a solid run of poor surf conditions, day after day.
Right now, the water temp is sitting at 64°F, which is about average for this time of year, nothing to write home about.
We kick off on Friday the 4th with onshore wind and messy 8ft swell. That sets the tone for the next week and a half. The swell energy does get strong, hitting 1607 (moderate to strong) on Monday the 7th, but that's with a full-on onshore wind. It’s just a big, blown-out mess.
For the first week, it’s a tough watch. Saturday the 5th has some size, 5ft with a long 12-second period from the WNW, and mild cross-on wind, but the call is marginal. Not great. There’s a brief flicker on Thursday the 17th – finally some gentle offshore wind from the ESE, but the swell is tiny at 4ft and the wave comment is just "very ordinary." On Friday the 18th there’s a bit more size, 6ft, again with offshore wind from the east, but it’s short-period stuff (6 seconds) and described as "ordinary."
Honestly, there are no standouts. Not one day in the whole 16 days is worth paddling out for. It’s a big, blank run of bad conditions. For a spot like Gwithian, it doesn’t often stay this poor for this long, so forecasts can change, but right now, if you want to surf, go somewhere else.
Stay optimistic, but don’t hold your breath.
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.
