The Lowdown
Alright folks, Rusty here. Let’s have a look at what the next couple of weeks have in store for us.
Right off the bat, I gotta be straight with you – it’s a tough stretch. We’ve got a lot of onshore wind and lumpy conditions making a mess of things for the first week. The real standout, and honestly the only time I’d be keen, is the morning of Saturday, September 5th.
Saturday September 5th is your window. We’ve got a glassy morning with the wind swinging light from the SW, and the water temp is sitting around 63°F, which is pretty normal for this time of year. The swell is a clean 5ft from the WNW with a lovely long period of 12 seconds – proper groundswell. The combined energy is solid (568), and that longer period means better shaped waves with more punch, though at a beach break like Gwithian it might want to jack a bit too straight. Still, with glassy conditions, this is the pick of the lot. If you’re a beginner, this is manageable size.
Saturday afternoon fades a bit with light cross-shore wind and smaller 4ft swell – still rideable but less exciting.
After that, we’re back into poor conditions. Sunday the 6th is tiny and clean but with only 2ft and weak energy (94), it’s hardly worth the paddle. Then Monday the 7th sees a big jump in swell energy (1280) with 7ft waves, but the WSW wind is howling onshore at 19 mph – that’s a blown-out, lumpy mess. That pattern of strong onshore winds continues through the whole second week. Into the second week, from around September 10th onward, we see some decent sized swell again (up to 8ft), but the wind is relentless from the west at 19 mph or more, onshore and messy.
The only other slight whisper of hope is a couple of mornings around the 11th and 12th, but the swell drops to 3ft-5ft with moderate cross-onshore chop. Not worth getting excited about.
In short: you’ve got one golden window on the morning of Saturday September 5th. Make the most of it, because the rest of the 16-day run is mostly a write-off with poor surf quality due to wind.
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.
