The Lowdown
Alright surfers, Rusty here, let’s take a look at what’s cooking for Gwithian over the next couple of weeks.
To be honest, the first week is a bit of a struggle. We’ve got a lot of onshore wind and marginal conditions to deal with. There’s a bigger pulse of swell arriving around Monday the 7th of September, with waves hitting 7ft from the WNW and a solid period of 13 seconds, but the wind is howling onshore from the WNW at 12 mph, so it’s going to be a messy, blown-out affair. The combined energy is strong at 1632, but it’s not really one for a fun paddle. There’s a lot of cross-shore and onshore wind through the following days, with a fresh breeze from the NW on the 11th making it lumpy. The water temperature is sitting at 63°, which is about average for this time of year.
The real window of opportunity opens up on Thursday the 17th of September. That morning we’ve got a clean 6ft WNW swell with a period of 8 seconds, but the wind is light and cross-offshore from the NE at 6 mph. The combined energy is 650, so there’s moderate power in the water. The afternoon is even better: glassy conditions with the wind dropping to a slight air from the ENE, and the swell settling to a clean 4ft, also from the WNW. This is the standout session if you can get in the water. The break is fairly exposed to the WNW, so it’ll be handling that swell nicely. Keep in mind, crowds are often here, so expect some company.
After that, we trail off into smaller, more ordinary conditions. The 18th and 19th have some clean morning windows with offshore winds and knee-to-waist high waves, but nothing to get too excited about. The 20th of September has a moderate offshore breeze from the ESE at 12 mph, keeping things clean, but the swell is a modest 4ft.
So, the call is clear: if you can wait, the 17th is your best bet for some clean, fun waves at Gwithian. The rest of the forecast is a mix of waiting and hoping for the wind to play ball.
Stay wet, 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.
Gwithian is 6 km (4 miles) from Camborne. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Camborne. Camborne has rooms for a wide range of budgets as well as car hire and transport links.
