The Lowdown

Alright, folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

Honestly, it’s a bit of a tough stretch. The first week or so is gonna be a real grind with hardly any surf to speak of. We’re looking at mostly small, weak waves with onshore and cross-shore winds messing things up. The water is sittin’ at a touch warmer than normal for the time of year, about 64°, so that’s a nice little bonus for the paddle out, but you’ll be bobbing around more than riding.

The pattern starts to shift a little around Sunday, July 26th. The morning shows a bit of life with swell height hitting 5ft from the WNW, but the wind is a fresh cross-onshore at 19 mph, which will make it lumpy. The combined energy is moderate at 174, so there’s some push, but it’s not gonna be clean. Not a day for the beginner, that’s for sure.

The pick of the whole outlook, and I mean the only real standout, looks to be Monday, July 27th. The morning session at Gwithian is where you wanna be. We’ve got a clean-looking 4ft swell from the WNW with a decent 9-second period, giving it some shape. The wind is a light cross-shore from the NNE at 9 mph, and the combined energy is a solid 252 – that’s moderate wave energy, the best we see in this whole run. It’s not massive, but it’ll be the most fun and rideable it gets. The wind is gentle, so expect a bit of cross-chop but nothing too nasty. This is a consistent spot, so there’ll be waves to go around, though crowds are often here, so don’t expect a solo session.

After that, things drop off again. The afternoon of the 27th is smaller, and by Tuesday, July 28th, the morning has a super clean window with offshore wind from the ESE at 6 mph, but the swell is tiny at 2ft. You might snag a few little ones on a longboard if you’re desperate, but the energy is weak (43). The rest of the run into the first week of August stays small and messy, with onshore winds and choppy conditions. The afternoon of Saturday, August 1st shows a spike to 5ft from the SW, but it’s a short-period 6-second windswell with a cross-onshore breeze, so it’ll be a bit of a washing machine. The combined energy is moderate (161), but the quality won’t be there for a proper paddle session.

So, bottom line: if you’ve got a window, make it Monday morning, July 27th. The rest of the time, it’s a waiting game. The setup is so poor for most of it that if you’re into kites, the windier, lumpier afternoons might look more interesting than a surfboard.

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.
