The Lowdown

Right then, let’s have a look at what’s cookin’ for Gwithian.

Honestly, the next week and a half is a bit of a write-off for any proper paddlin’. We’ve got a long, frustrating gap of small, messy, or just plain blown-out surf stretchin’ from now all the way through the first few days of September. There’s a few moments with clean, offshore wind, but the swell is just too weak – we’re talkin’ 0.7ft to 2ft stuff with combined wave energy barely gettin’ into triple digits (31 to 115). It’s not worth wettin’ a wetsuit for.

Now, the surf finally wakes up around the 27th of August, Thursday afternoon. The swell jumps to 6ft out of the SSW, with a modest 9-second period and combined energy of 639 – that’s moderate. The wind turns light cross-off from the south, so it’ll be clean. But honestly, the ratings are poor, so it’s not the standout. Friday the 28th gets messy with onshore wind, and the weekend is a howlin’ cross-onshore mess with chop.

The first proper standout comes on Sunday the 6th of September. After a grim run of weather, the afternoon delivers. A solid 10ft swell from the WNW with a 9-second period, and the combined energy is a hefty 1396 – that’s serious power. But the real beauty is the wind: glassy. Dead calm, perfect conditions. This is only goin’ to be for the experienced crew though – 10ft is big, and even though it’s a beach break, that kind of size will be a handful. The water temp is 63°F, which is normal for this time of year.

Then we get Monday the 7th of September. The morning sees a 6ft swell from the W with a longer 10-second period and an offshore breeze from the ESE, combined energy of 1082. That’s lookin’ clean and punchy. But the real headline is the afternoon: a massive 12ft swell from the WSW, combined energy of 1351, with a fresh offshore wind from the ESE. That’s gonna be absolutely thumping, but it’s predicted to be too big for Gwithian – that’s expert territory only and even then, it might be a battle just to get out. If you’re a confident charger, that Monday afternoon window is the one to watch, but it’s a long-range call, so keep an eye on it.

So, bottom line: the first week is a near-total blank. The true standout is the glassy 10ft session on Sunday the 6th of September. Second best is the offshore, 6ft surf on Monday the 7th morning. Don’t hold your breath for the rest.

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.
