The Lowdown
Right, folks, Rusty here. Let’s have a look at what’s cookin’ for Gwithian over the next couple of weeks.
Straight off the bat, I gotta be honest with you – this is one of those stretches where the ocean just isn’t playin’ ball. The whole 16-day window is a bit of a write-off for proper surf. We’ve got nothing but “poor surf conditions” stamped all over the forecast, and the scores are all flat-out zeros. It’s a grim run, and I’d say you’re better off leaving the boards in the shed.
Looking at the first week, we start on Monday the 20th of July with a tiny 2ft swell from the north, but with a short, weak period of 5 seconds and only 35 units of combined energy – that’s barely a ripple. The wind is light offshore in the morning, so it’ll look clean, but there’s just no power behind it. The combo of a weak, short-period swell and a north direction means it’s not going to wrap in properly. It’s a flat, clean, frustrating morning.
Tuesday and Wednesday see a bit more height, up to 4ft, but it’s still from the north, with a short period and moderate to fresh cross-shore winds. That’s gonna be lumpy, choppy, and pretty much unsurfable. Thursday the 23rd offers a clean morning with light offshore winds again, but only 3ft of weak, north windswell. It’ll look pretty, but it’s a tease.
The end of the first week and into the second gets a bit bigger, but not better. Saturday the 25th has onshore winds blowing hard at 19 mph, and by Sunday the 26th, we see a 7ft swell from the west with a 7-second period and a combined energy of 483 units – that’s moderate energy, but with fresh onshore winds, it’s just a messy, blown-out wall of white water. That’s not for beginners, and for experts, it’s a washing machine. Honestly, if you’re into kite surfing, this setup might look interesting, but for a paddle surfer, it’s a hard pass.
The second week (from the 27th of July onwards) is more of the same: small to moderate swells, but always with some cross or onshore wind, and the conditions are consistently described as poor. We see a few clean moments, like the morning of the 31st of July with a light onshore breeze and a 4ft swell from the west, but the period is short and the energy is only moderate. It’s just not enough to clean up the quality.
The standout? There isn’t one. Not a single session in this 16-day stretch gets a recommendation. The water temperature is about average for the time of year, so that’s not a problem, but the lack of any decent swell window is a real bummer. This is a blank run for Gwithian, and honestly, it’s the kind of poor run that’s more normal for the area when the wind doesn’t play nice. Forecasts can change, but right now, I’d say don’t hold your breath.
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.
