The Lowdown
Alright, let's get into it – this is Rusty, checkin' in for the Cornwall forecast.
Right off the bat, I gotta be straight with you, it's a tough start. We're looking at Gwithian, and for the first week, it's a proper battle. That Sunday morning (9th of August) kicks off with a tiny 1ft lump from the WNW, but the wind is a cross-on at 9 mph, making it a choppy, messy mess. The energy is weak at 36, and it's labelled as poor surf conditions. Basically, don't bother. This flat spell hangs around for a while. The whole first week is a write-off with tiny swell and rubbish wind.
We do see a little flicker on Wednesday morning (12th of August). The swell pushes up to 3ft from the west, period around 10 seconds, and the wind swings offshore from the ENE at 9 mph. The water is clean, and the energy is getting into the moderate range at 132. It's described as "surfable waves but very ordinary conditions," and honestly, with a score of 1, it's just a bit of a tease. Still, if you're desperate, that's the one window.
Otherwise, it's a long grind of cross-shore and cross-onshore winds, with the swell staying under 4ft, and the energy occasionally nudging into the low 100s. Thursday the 13th has a 4ft swell from the west, but the wind is a cross-on from the NNW at 12 mph, making it choppy. The energy is there at 279, but the quality is shot.
The weekend of the 15th and 16th gets a bit more size – 5ft from the north on Sunday morning – but it's a short-period, messy windswell with the wind howling cross-shore at 15-18 mph. That's more kite-surfing territory than paddle surf. The energy jumps to 254, but it's rough.
Honestly, the standout – and I'm using that term loosely – is the very end of the forecast. The morning of Monday the 24th of August. The swell is up to 6ft from the west, with a period of 7 seconds, and the energy is a solid 491. The wind is a gentle cross-shore from the NNE at 9 mph, and we get a "gentle cross-shore with slight cross-chop." It's a big, raw windswell, so it's not going to be a thing of beauty, but it's the biggest push of the whole period. The conditions are still marginal, but it's the only time the size and wind are close to working together. It's going to be a bit of a battle, but for the big boards and a bit of grunt, that's your window.
So, for the next 16 days, there's really only one day that looks worth a session: the morning of the 24th. Everything else is a wait-and-see or a write-off. Keep your eyes on the charts, but 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.
