The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming down the line for the next couple of weeks.
Honestly, it’s a bit of a waiting game. For the next week and a half, the surf at Gwithian is there, but it’s just not coming together. The wind is the main problem. It’s either blowing cross-shore or cross-onshore most of the time, which is making a mess of what swell we get. The water temp is about average for this time of year, so nothing unusual there.
Thursday the 10th kicks off with a small 4ft WSW swell, but with a 15 mph cross-wind and a short 6-second period, it’s a no-go. The combined energy is weak at 114, and the waves will be poor. We get a bump in size Friday morning the 11th – a clean 5ft W swell with a light offshore breeze from the NW. That’s the best looking window in the first week. The period pushes to 9 seconds, and the energy is moderate at 367. It’s beginner-friendly size, and with that offshore wind, it’ll be clean. That’s your best chance for a proper surf in the early run.
The wind turns bad again after that. Saturday the 12th and Sunday the 13th see more cross-shore and cross-onshore wind with messy, choppy conditions. The swell hangs around 5ft to 6ft, but it’s not worth paddling out. The rest of that week and into the next is the same story – small to moderate swell, but the wind just can’t get its act together. There are long gaps here where there’s nothing to recommend.
The stand-out on offer is way out in the long-range. Look at Sunday the 20th of September. We’ve got a solid 10ft WNW swell rolling in. The combined energy is strong at 1109. That’s a serious push of water. The morning has a 15 mph cross-wind from the N, which is going to keep it a bit lumpy, but for experienced surfers at a low tide, this is the biggest and most powerful swell of the forecast. The period is only 8 seconds though, so it’s shorter period wind swell and it will be a bit walled up. 10ft is expert territory. If you’re a beginner, stay well clear of this one.
Then on Tuesday the 22nd of September, we get another big pulse. A 8ft WNW groundswell with a long 11-second period. The combined energy is very strong at 2889. The wind is a 12 mph cross-onshore from the WSW though, which will put a chop on it. It’s a lot of power, but not the cleanest conditions.
So, the bottom line: The first week is a write-off for quality. Friday morning the 11th is your only real window for a clean, easy-going session. The real power shows up on Sunday the 20th with a big 10ft swell, but that’s only for the brave. The 22nd has more size and a long period, but the wind is a let down. The rest is poor.
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.
