The Lowdown
Alright folks, Rusty here. Let’s break down what’s on the cards for Gwithian over the next couple of weeks. I’m gonna be honest – it starts off rough, but there’s a proper session waiting for us if you can hang tight.
Right now, the pattern is messy. The first several days are all onshore and cross-shore winds, making a mess of things. The water temp is about 64°, which is a touch warmer than usual for this time of year – nothing wild, but it’s a nice little bonus.
The first real chance to get wet comes on Friday, September 11th. That morning, we get a cross-off wind from the SSE, with a 5ft swell from the WSW, 9-second period. The energy is moderate (287), and it’s looking clean. Not a huge day, but after the slop we’ve been dealing with, it’ll be a relief. Friday afternoon gets even better with a light offshore from the SE, dropping to 3ft – small but glassy.
Then it’s back to the grind. Saturday the 12th gets messy with strong cross-shore winds, and the following days are mostly onshore junk. The swell hangs around, but the wind won’t cooperate.
Now, here’s the one you’ve been waiting for. Sunday, September 20th is the standout. Gwithian is a fairly exposed beach break, and this day it’s all coming together. We’ve got a 7ft swell from the W, with an 11-second period – that’s proper groundswell. The combined energy is strong (1056). The wind is the real story: a solid ESE offshore at 15 mph in the morning, easing to 15 mph in the afternoon. That’s clean, glassy surf all day. The guidance says the best direction for Gwithian is WNW, so this W swell is right in the zone. It’s going to be firing. Just a heads up – 7ft can be a handful for beginners, but for the rest of you, this is the session to chase.
Monday, September 21st is a nice follow-up. The offshore holds from the ESE, but the swell drops to 4ft and the energy backs off to 245. It’s still clean, but not as punchy.
So, the first week is a bust unless you’re after a small, clean wave on Friday the 11th. The real prize is that Sunday the 20th – get it on your calendar. It’s a long way out, so keep checking, but the signs are looking good.
Stay stoked,
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.
