The Lowdown
Alright, folks, Rusty here. Let’s have a look at the next couple of weeks for our stretch of coast. It’s a bit of a mixed bag, so let’s break it down.
The first thing you need to know is that the start of this period is a total write-off. We're looking at a stretch of poor, unsurfable conditions with onshore and cross-onshore winds and lumpy, chopped-up surf. It’s going to be a frustrating few days for sure, but that's the way it goes. Don't even bother checking the cams until things shift.
We're talking about a gap of nearly two weeks from today, the 10th, right through to the 23rd, where there is nothing on offer. The swell is there, but the wind and the shape are just all wrong. We see a bit of a pulse on the 16th, with a solid 6ft of W-NW swell, but it's paired with a cross-onshore N wind at 15 mph, making it a messy, choppy mess. Not worth your time.
Then, the whole game changes. The 24th is where it starts to get interesting. Thursday morning is looking like the first real glimmer of hope. We've got a clean 8ft swell rolling in from the W, with that energy jumping to 781 (moderate-to-strong), and a light cross-offshore S breeze at 6 mph. This is a proper surfable wave, and a big step up from what we've had.
But it’s that Thursday afternoon that is the standout. The wind goes glassy, dropping to 3 mph from the S-SW, and the swell just lights up. We're talking a 12ft W-NW swell with a super long 15-second period. The combined energy here is massive – 6249 (very strong) – and this is the real deal. The forecast is for "very good surf conditions." Now, here's the catch: 12ft is big. This is expert territory. The long period will make it a lot for the average surfer. It’s the kind of day where you want to be watching from the cliffs if you aren't a serious charger. It will be too big for the beginners for sure.
Then we get into Friday the 25th. The wind swings to a fresh off-shore E-SE at 19 mph, which is great for keeping the surface clean. We've still got a big, powerful swell – 10ft from the W with a 13-second period and energy at 5460 (very strong). It's a bit smaller than Thursday, but still well overhead and powerful. The forecast is calling it marginal, and it's probably on account of the sheer size and power, which will make it a tough paddle. It's still only for experts.
So, if you're a competent surfer, that Thursday afternoon is your window. The combination of the glassy wind, the huge groundswell, and the perfect direction makes it the one to circle on the calendar. Friday is also solid, but the strong wind and massive swell will test you.
For the rest of us, we just gotta be patient and wait for the next window. The water temp is a touch warmer than normal for this time of year, coming in at 64°F, so we won't be freezing our backsides off while we wait.
Keep it salty.
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.
