The Lowdown

Alright folks, Rusty here. We’re looking at the 16-day window for Gwithian, and I’ve got to be straight with you – it’s a tough stretch. There’s a lot of onshore wind and messy conditions in the forecast, so don’t expect too many clean lines.

The first real chance to get wet looks like Saturday morning, the 22nd of August. We’ve got a tiny 2ft swell from the north, but the wind is off the land from the east at 9 mph. That’s going to make for a glassy, clean surface. The wave energy is low though, and the period is a short 6 seconds, so it’ll be a bit weak and lumpy. It’s surfable, but you’ll be working for every little ride. The water temp is 64°F, which is just about average for this time of year, so no wetsuit drama.

After that, we hit a massive dry spell. From Sunday the 23rd right through to Tuesday the 26th, the surf is either tiny, onshore, or both. There’s a small window on Wednesday morning, the 26th of August, with a 4ft SSW swell, but it’s cross-shore wind at 16 mph, so it’ll be a choppy mess. The afternoon improves a little with a 5ft SSW swell and lighter cross-shore wind, but the energy is still moderate, and the 8-second period isn’t doing it any favours. It’s marginal, not a standout.

The next real event is further out. Saturday the 29th of August sees a bigger 8ft swell from the west-northwest, but the wind is onshore from the west-northwest at 16 mph. That’s a lot of power but it’s going to be blown out and messy. For a beginner, that’s too big and ugly. For an expert, it’s a wild, windy day. The afternoon stays similar at 7ft with onshore wind.

Sunday the 30th of August drops off fast, with only 3ft to 3ft of weak, short-period swell and cross-shore winds. Not worth the paddle.

Looking way out, there’s another pulse on Thursday the 3rd of September. A 7ft swell from the west-southwest hits with a near gale (31 mph) cross-shore wind. That’s a massive wave energy, but the wind will be shredding the surface. For the few brave souls, Friday the 4th of September might offer a cleaner, smaller 5ft swell from the west with a gentle cross-onshore wind. It’s the best of a bad lot in the second week, but still not a classic.

Honestly, if you’re a surfer, the only spot that holds any real hope is Gwithian itself, and that’s on Saturday morning the 22nd. It’s a beginner-friendly break, but it’s inconsistent and often crowded. For the rest of the 16 days, the setup is more interesting for the kite surfers than us paddle surfers. The forecasts can always change, but right now, it’s a waiting game.

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.
