Table - best surf conditions forecast for Gwithian over the next 16 days.


Alright folks, Rusty here. Let’s be straight with you: the next 16 days at Gwithian are a tough watch. We’re looking at a long stretch of flat, weak, and messy conditions. The energy is just not there for a proper session, and most of the time the swell is puny with poor shape.

We kick off on Sunday, 12 July, with a tiny 2 ft swell from the north, but it’s short-period windswell at 6 seconds and the combined energy is a measly 43 – that’s weak. The wind is howling out of the east at 19 mph, which is cross-offshore, so it’s clean but frankly there’s nothing to ride. This theme continues straight through the next week. Monday and Tuesday see similar 2 ft to 3 ft dribble, with fresh easterly winds keeping the surface clean but the surf is hopeless. The water temperature is about average for the time of year, nothing unusual.

There’s a brief moment on Tuesday, 21 July, where the wind goes glassy – a light southwesterly and then westerly at just 3 mph – and the ocean turns to a mirror. But the swell is only 1 ft from the west-northwest with a period around 10 seconds. The energy is still weak (58 and 36). It’s pretty, but not surfable. Kite surfers might have a slight interest on some of the windier days, but for us paddlers, it’s a no-go.

The only real standout, and it’s a long way off, happens on Monday, 27 July. A solid 6 ft swell from the west rolls in, with a period of 9 seconds. The combined energy jumps to 663 – that’s moderate to strong energy, and the first real pulse we’ve seen. However, the wind is light and onshore from the west-northwest, so it’s going to be bumpy. At 6 ft, this is pushing into the zone for beginners; it’s more of an intermediate to expert wave. But after two weeks of flatness, it’s the only time the ocean wakes up. Keep an eye on it, but it’s a long way off and the wind could easily mess it up.

So, the bottom line: the next 16 days are mostly a write-off at Gwithian. The only flicker of hope is that 27 July swell. Don’t hold your breath, but check back closer to the date.

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.
