The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for Gwithian over the next couple of weeks.
Right off the bat, we’ve got a rough stretch. Wednesday and Thursday are a write-off with onshore slop and messy cross-shore junk. Friday the 4th has some size, with 8ft of swell coming from the west, but it’s still blown out with onshore wind. Not a pretty picture for the paddle crew. The combined energy is up there (823), but it’s a messy lump.
Now, the first real glimmer comes on Saturday the 5th of September. We get a morning with light offshore wind from the southeast and only 3 mph, clean conditions, and a nice 4ft groundswell from the WNW with a period of 11 seconds. That’s a long-period groundswell – better shaped, plenty of energy – and it’s gonna wrap in nicely here. The combined energy is solid at 440. The water temp is sitting at 63°F, which is about average for this time of year, nothing wild. Gwithian can get busy (crowds are often), but with clean surf and an offshore wind, it’s worth the company.
Sunday the 6th drops right off – tiny 2ft and weak energy – so that window closes fast. Then we get a big messy pulse on Monday the 7th with 7ft but onshore winds again. The rest of the first week is a mix of blown-out conditions and onshore crud, nothing to get excited about.
Looking further ahead, the week of the 11th of September shows some promise but comes with a lot of wind and size. Friday the 11th has 10ft of west swell, but it’s onshore and marginal – big enough only for experts if the tide plays ball. Combined energy is a massive 1406, but it’s a bit of a beast with short period (8-9 seconds) and onshore wind. Not clean.
Saturday the 12th looks like the other standout. Morning has 7ft of west swell with a long period of 12 seconds, and a cross-off wind from the south at 12 mph. That’s clean and powerful. Combined energy is 1365, very strong. This is one for experienced surfers – over 8ft is expert territory. Keep an eye on that one.
After that, it fades again, with onshore winds and lumpy conditions through the middle of the month. There’s a gap of a few days with no real recommendations after the 14th, with small to moderate swell but poor quality wind. The 15th has a big period (13 seconds) and 7ft, but it’s onshore wind – not worth the paddle.
So, to sum it up: the best bets are Saturday the 5th of September for a clean, fun size, and Saturday the 12th for a bigger, more powerful session but only if you’re comfortable in the 7ft+ range.

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.
